The Case of The Missing water Summary in English and Tamil

The tank in Divya’s village was almost dry. Ammachi began to pray for rain. Amma collected all the buckets and pots and vessels in the house and filled them up.. “We need to store as much water as we can,” she said. Appa collected tools to dig a little deeper. “We just need enough until the rains arrive,” he said.

திவ்யாவின் கிராமத்திலிருந்த குளம் பெரும்பாலும் வறண்டு விட்டது. அம்மாச்சி மமை வரவேண்டுமென பிரார்க்கனை செய்தார். வீட்டிலிருந்த வாளிகள், பானைகள், பாத்திரங்கள் எல்லாவற்றையும் எடுத்து, அவற்றில் நீரை நிரப்பி
வைத்தாள் அம்மா. “நம்மால் முடிந்த அளவுக்கு தண்ணீரை சேமிக்க வேண்டிய தேவை ஏற்பட்டுவிட்டது”, என்றாள் அம்மா. கொஞ்சம் ஆழமாகத் தோண்டு வதற்கான கருவிகளை அப்பா சேகரித்தார். “மழை வரும் வரையில் நமக்கு இது தேவை”, என்றார் அவர்.

Divya got out her notebook and pencil. She put on her thinking cap and followed her parents to the tank. She examined the tank bed closely. It was cracked and dusty.

திவ்யா ‘ தனது நோட்டு புத்தகத்தையும் பென்சிலையும் எடுத்துக் கொண்டாள். தனது பெற்றோரை பின்தொடர்ந்தபடி குளத்திற்குச் சென்றாள். வெகு அருகிலிருந்தபடி குளத்தை அவள் ஆய்வு செய்தாள். நிலத்தில் பிளவு ஏற்பட்டு, தூசி படிந்திருந்தது.

Divya wondered, “Where did the water in the tank go? Did it run away? Was it stolen? This is a mystery!” Divya loved solving mysteries: Like the time Ammachi couldn’t find her reading glasses. Divya had found them in her book, marking the page she was reading. “I’ll find that water,” Divya muttered to herself.

திவ்யா ஆச்சர்யப்பட்டாள். “குளத்திலிருந்த தண்ணீர் எங்கே போனது? அது ஓடிவிட்டதா? திருடப்பட்டுவிட்டதா? இது ஒரு மர்மம்”, என்றாள். மர்மங்களுக்கு தீர்வு காண்பதை திவ்யா விரும்பினாள். படிப்பதற்கான கண் கண்ணாடியை அம்மாச்சி கண்டுபிடிக்க முடியாமல் போன சமயத்தில் நடந்ததைப் போல.

அவருடைய புத்தகத்தில், படித்த பக்கத்தை குறிப்பிட வேண்டி, அது வைக்கப்பட்டிருந்ததை திவ்யா கண்டுபிடித்துக் கொடுத்தாள். “அந்த தண்ணீரையும் நான் கண்டுபிடிப்பேன்,” என திவ்யா தனக்குள் முணுமுணுத்துக் கொண்டாள்.

Divya walked to the other side of the tank, past dead fish and dried reeds. “Do you know where the water could have gone?” Divya asked a fisherman. “Downstream?” the fisherman suggested. Divya followed the dry stream bed down the hill. At the bottom was another tank. It had lots of goats, but no water.

திவ்யா குளத்தின் மறுகரைக்கு நடந்தாள். இறந்து போன மீன்களையும், காய்ந்து போன நாணல்களையும் கடந்தாள். “தண்ணீ ர் எங்கே போயிருக்க முடியுமென உங்களுக்கு தெரியுமா?” என ஒரு மீனவரைதிவ்யா கேட்டாள்.

“கீழ்மட்டத்திற்கு போயிருக்கலாம்,” என்றார் மீனவர். குன்றின் அடியிலிருந்த, வறண்டு போன நீரோடையில் திவ்யா நடந்தாள். கீழே இன்னொரு குளம் இருந்தது. அங்கு பல ஆடுகள் மேய்ந்த படி இருந்தன, ஆனால் நீர் இல்லை.

Divya asked the goatherd, “Do you know where the water might be?” “Upstream,” the goatherd suggested. I “That’s where I came from,” Divya said. “No water there.” “Further up, then?” the goatherd said. “That’s where your water comes from.”

திவ்யா ஆடு மேய்ப்பவரிடம், “தண்ணீ ர் எங்கே போயிற்று என உங்களுக்குத் தெரியுமா?” என கேட்டாள். ஆடுமேய்ப்பவர், “மேல் மட்டத்திற்கு போயிருக்கலாம்” என்றார். “அங்கிருந்து தான் நான் வருகிறேன், அங்கு தண்ணீர் இல்லை” என்றாள் திவ்யா. “அதற்கும் மேலே. அங்கிருந்துதான் தண்ணீர் வருகிறது”, என்றார் ஆடு மேய்ப்ப வர்.

Divya climbed up to the tank. Then she climbed up some more to a tank further up the hill. There was no water, no birds. There was only one person there. “Rani, I can’t find any water. Any idea where it’s gone?” Divya called to her. She knew Rani from school.

“Downstream,” Rani called back. Divya was suddenly angry. She stomped her foot. “No!” she shouted. “It’s not. I
have searched and searched. It’s not upstream or downstream. Got it?”.

திவ்யா குளத்தை நோக்கி குன்றின் மேலே ஏறினாள். அங்கு இருந்த ஒரு குளத்தில் தண்ணீ ரும் இல்லை, பறவைகளும் இல்லை. ஒரே ஒரு பெண் மட்டும் இருந்தாள். “ராணி, தண்ணீரையே பார்க்க முடியவில்லை. அது எங்கே போயிற்று என்று ஏதாவது ஐடியா இருக்கிறதா?”

என திவ்யா அவளைக் கேட்டாள். பள்ளியிலிருந்தே ராணியை அவளுக்குத் தெரியும். “கீழ் மட்டத்தில்”, என்றாள் ராணி. திவ்யா திடீரென கோபப்பட்டாள். தரையை காலால் தட்டினாள்.

“இல்லை” என கூச்சலிட்டாள். “அங்கே இல்லை. நானும் தான் தேடினேன்-தேடினேன். அது மேல்மட்டத்திலும் இல்லை, கீழ்மட்டத்திலும் இல்லை. புரிந்ததா?”

“How about up there?” Rani suggested. Divya and Rani looked up at the sky.” The sun glared back at them. Everything was white-hot and dusty. “No,” they agreed together. “No water there. Divya collapsed into the boat with Rani and gnawed on a lotus stem. She was hot and tired.

அது இன்னும் உயரே சென்றிருக்கலாம்,” என்றாள் ராணி. திவ்யாவும், ராணியும் வானத்தைப் பார்த்தனர். சூரியன் அவர்களின் மீது ஒளியை பாய்ச்சியது. எல்லாமே வெள்ளையாக-வெப்பமாகவும், தூசியுடனும் இருந்தன. “இல்லை, அங்கே தண்ணீர் இல்லை”, அவர்கள் இருவருமே ஒரு சேர ஒப்புக் கொண்டனர். திவ்யா, ராணியுடன் படகில் சாய்ந்தபடி, ஒரு தாமரைத் தண்டை கடித்தாள். அவள் உடம்பு வெப்பத்தால் தகித்தது. அவள் களைப்படைந்தாள்.

“Manju’s parents left the village, “Divya said. “They went to the city” where they have water. Maybe we should all go.” “You go,” Rani snapped. “No one asked you to be here.” “Fine,” Divya said. And she stomped back home. But it wasn’t fine! There was still no water, still no rain.

மஞ்சுவின் பெற்றோர் இந்த கிராமத்தை விட்டுச் சென்று விட்டனர். நகரத்துக்குப் போய் விட்டனர். அங்கு அவர்களுக்கு தண்ணீ ர் கிடைக்கும். நாம் எல்லோரும் போக வேண்டி வரலாம்”, என்றாள் திவ்யா. “நீபோ, இங்கேயே இருக்கவேண்டுமென உன்னை
யாரும் கேட்டுக் கொள்ளப் போவதில்லை”, என்றாள் ராணி. “நல்லது” என்றாள் திவ்யா. அவள் வீட்டுக்குத் திரும்பினாள் ஆனால் அங்கு சூழ்நிலை சரியில்லை. இன்னும் அங்கு தண்ணீர் இல்லை, மழையும் இல்லை.

The next day, Divya brushed her teeth with muddy tank water in a tiny glass. “Thooo!” she spat. In school, the class was half-empty. More families had left the area. She missed all her friends! In the middle of Environmental Studies class, she turned and ran out of school. She ran and ran until she was panting. She finally sat at the side of the road.

அடுத்த நாள். சேறுகலந்த குளத்து நீரை ஒரு சிறிய கிளாஸில் வைத்துக் கொண்டு, திவ்யா பல் துலக்கினாள். “த்தூ!” என அவள் துப்பினாள். பள்ளியில் பாதி வகுப்பு காலியாக இருந்தது. அந்தப் பகுதியிலிருந்து மேலும் பல குடும்பங்கள் சென்று விட்டிருந்தனர்.

அவள் தன் எல்லா நண்பர்களையும் இழந்தாள். வகுப்பில், சுற்றுச்சூழல் பாடத்தின் நடுவே, அவள் எழுந்து, பள்ளியை விட்டு ஓடினாள். மூச்சிறைக்கும் வரை அவள் ஓடினாள். இறுதியில், சாலையின் ஒரு புறத்தில் அவள் அமர்ந்தாள்.

“I have to find the water!” she huffed. “Can I help?” said a voice. It was Rani who had seen Divya running away” from school. Divya beamed. “Yes!” “We have to do this properly,” Rani said. “Like real Sanitary Engineers.” “Like who…?” Divya asked. “Sanitary Engineers build pipes and tanks and drains. I am going to be one when I grow up,” Rani said. Divya and Rani decided to draw a map of their village and all its tanks and streams, showing all the places where the water might have flowed.

தண்ணீர் எங்கே போனது என நான் கண்டுபிடிக்க வேண்டும்”, என்று ஒரு வித கோபத்துடன் “உனக்கு உதவட்டுமா”, என்றது ஒரு குரல், அது ராணி தான். பள்ளியிலிருந்து திவ்யா ஓடிவந்ததை அவள் பார்த்தாள். “சரி”, என்றாள் திவ்யா.”சுகாதாரப் பொறியாளர்களைப் போல, நாம் இதை சரியாகச் செய்ய வேண்டும்”, என்றாள் ராணி. “யார் அவர்கள்?”, என்று திவ்யா கேட்டாள்.

“குழாய்கள், தொட்டிகள், வடிகால் வாய்க்கால்களை கட்டுகிறார்களே அவர்கள் தான். நான்பெரியவளாக வளர்ந்த பிறகு சுகாதாரப் பொறியாளராவேன்,” என்றாள் ராணி. அவர்களின் கிராமத்தின் வரைபடத்தை அவர்கள் இருவரும் வரைய தீர்மானித்தனர். மேலும் தண்ணீர் செல்லக்கூடிய வழித்தடங்கள், குளங்கள், ஓடைகள் எல்லாவற்றையும் வரைபடத்தில் குறிக்கவும் முடிவு செய்தனர்.

Where could the water possibly have gone? Finally, they sat back and pored over the map. “We haven’t seen that tank yet,” Divya pointed to one of the tanks they had drawn. “Let’s go,” Rani agreed. Divya and Rani began climbing up the hill. The stream here was dry as well.

தண்ணீ ர் எங்கே போயிருக்க கூடும்? இறுதியாக, அவர்கள் தரையில் அமர்ந்து, வரைபடத்தை கூர்ந்து ஆராயத்தொடங்கினர். “அந்தக் குளத்தை இதுவரை நாம் பார்க்கவில்லை, அவர்கள் வரைந்த குளங்களில் ஒன்றை சுட்டிக்காட்டியபடி, திவ்யா இவ்வாறு கூறினாள். “நாம் போகலாம்”, ராணி சம்மதித்தாள். ஏறத் தொடங்கினர். அந்த ஓடையும் வறண்டு திவ்யாவும், ராணியும் அந்தக் குன்றின் மீது போயிருந்தது.

“Maybe we shouldn’t have missed school. This tank is probably dry as well,” Rani said sadly. When they reached the tank, Divya” and Rani realised they were wrong. This tank was full! Rani pointed at a small pump at the end of the lake. There was a tanker just below the bund, collecting water as it flowed. A man stood by, guiding the tanker. “Mystery solved,” said Divya angrily.

நாம் பள்ளிக்குச் செல்வதை தவற விட்டிருக்கக் கூடாது. இந்தக் குளமும் வறண்டிருக்கிறது”, என்றாள் ராணி வருத்தமாக. குளத்தை அவர்கள் அடைந்தபோது, திவ்யா, ராணி இருவருமே தங்களது யூகம் தவறு என உணர்ந்த னர். அந்தக் குளத்தில் தண்ணீ ர் நிரம்பியிருந்தது.

அங்கு ஏரியின் முடிவில் ஒரு சிறு பம்ப் இருந்ததை ராணி சுட்டிக்காட்டினாள். கரைக்குக் கீழே ஒரு டேங்கர் (நீர் ஏற்றிச் செல்லும் வாகனம்) இருந்தது. அதில் தண்ணீர் நிரப்பப்பட்டுக் கொண்டிருந்தது. அதனருகில் ஒரு மனிதன் நின்றிருந்தான். “மர்மம் தீர்க்கப்பட்டது”, என்றாள் திவ்யா கோபத்துடன்.

“Where are you taking our water?” Divya wanted to know. “The city,” the man said. “I need to supply nine-thousand litres today!” “That’s not fair!” Rani said. The man shrugged, “That’s how it is.” “My friend is a Sanitary Engineer, Divya yelled. “She knows what’s fair.” The man laughed.” Sanitary Engineer it seems! You’re just children!” Rani said quietly, “Yes, but I know you can’t just take our water away.”

“எங்கள் தண்ணீ ரை எங்கே எடுத்துப் போகிறீர்?” என்று திவ்யா கேட்டாள். “நகரத்திற்கு, இன்றைக்கு நான் 9,000 லிட்டர் தண்ணீ ரை சப்ளை செய்தாக வேண்டுமே”, என்றான் அந்த மனிதன். “அது நியாயமல்ல”, என்றாள் ராணி.” “அது அப்படித்தான்,” என்றான் அவன் தன் தோள்பட்டையை உயர்த்தியபடி, “என் நண்பர் ஒரு சுகாதாரப் பொறியாளர்.

அவருக்கு எது நியாயமெனத் தெரியும்,” என்று திவ்யா சத்தமிட்டாள். அந்த மனிதன் சிரித்தான். “துப்புரவாளர் என்று தோன்றுகிறது. நீங்கள் எல்லாம் குழந்தைகள்தான்,” என்றான் அவன். “ஆம். ஆனால், நீங்கள் எங்கள் தண்ணீ ரை எடுத்துச் செல்ல முடியாது,” என்று ராணி அமைதியாகச் சொன்னாள்.

“Go home,” the man said. “You can’t change anything!” Divya had an idea. She hugged the pump. “You can’t turn it on now!” Rani ran up to hug the pump too. “Hey!” said the man. Now he was really angry. “Just go home,” he said.

“வீட்டுக்குப் போங்கள், உங்கள் இருவரால் எதையும் மாற்றிடவிட முடியாது”, என்றான் அவன். திவ்யாவுக்கு ஒரு யோசனை தோன்றியது. அவள் அந்த “பம்ப்”-ஐ கட்டி அணைத்துக் கொண்டாள். “இப்போது உங்களால் இந்த பம்ப்-ஐ திருப்ப முடியாது.” ராணியும் ஓடிச்சென்று’ பம்ப்-ஐ அணைத்துக் கொண்டாள். இப்போது அந்த மனிதன் உண்மையிலேயே கோபப்பட்டான். “வீட்டிற்குப் போய் விடுங்கள்”, என்றான்.

That was when the clouds broke, and rain poured. “The ‘monsoon is here!” Divya shouted. “I’m going home, even if you aren’t, the tanker man said. It rained and rained. WOOSH, the bund overflowed, and the stream rushed down, splashing them.

அப்போது மேகங்கள் உடைந்து, மழை பெய்தது. “பருவமழை இங்கே ஆரம்பம்”, திவ்யா சத்தமிட்டாள். “நீங்கள் போகாவிட்டாலும், நான் வீட்டிற்குப் போகிறேன்”, என்று அந்த டேங்கர் மனிதன் கூறினான். மழை தொடர்ந்து பெய்தது. ஊஷ், குளம் நிரம்பி வழிந்தது. நீரோடையில் தண்ணீர் பாய்ந்து அவர்கள் மீது, தெறித்தபடி, கீழ்நோக்கி ஓடியது.

“The water has been found! Mystery solved!” Divya said. “WOOOOOO!” They yowled with joy.

“தண்ணீர் கண்டுபிடிக்கப்பட்டுள்ளது! மர்மம் தீர்ந்தது”, என்றாள் திவ்யா. “ஊ…” அவர்கள் மகிழ்ச்சியுடன் குரல் எழுப்பினர்.

Question 5.
Write about the types of markets and their functions.
Answer:
On the Basis of Geographic Location:

  1. Local Markets: In such a market the buyers and sellers are limited to the local region or area.
  2. Regional Markets: These markets cover a wider are than local markets like a district, or a cluster of few smaller states
  3. National Market: This is when the demand for the goods is limited to one specific country. Or the government may not allow the trade of such goods outside national boundaries.
  4. International Market: When the demand for the product is international and the goods are also traded internationally in bulk quantities, we call it an international market.

On the Basis of Time:

  1. Very Short Period Market: This is when the supply of the goods is fixed, and so it cannot be changed instantaneously. For example the market for flowers, vegetables. Fruits etc.
  2. Short Period Market: The market is slightly longer than the previous one. Here the supply can be slightly adjusted. Example: The demand of fish, milk or egg,
  3. Long Period Market: Here the supply can be changed easily by scaling production. So it can change according to the demand of the market.

On the Basis of Nature of Transaction

  1. Spot Market: This is where spot transactions occur, that is the money is paid immediately. There is no system of credit.
  2. Future Market: This is where the transactions are credit transactions. There is a promise to pay the consideration sometime in the future.

On the Basis of Regulation:

  1. Regulated Market: In such a market there is some oversight by appropriate government authorities. For example, the stock market is a highly regulated market.
  2. Unregulated Market: This is an absolutely free market. There is no oversight or regulation, the market forces decide everything.

On the basis of Nature of competition:

  1. Monopoly: Monopoly refers to a market structure in which there is a single producer or seller that has control over the entire market. This single seller deals in products that have no close substitutes.
  2. Monopolistic Competition: Monopolistic competition refers to a market situation in which there are a large number of buyers and sellers of products.

Question 13.
The number of solutions of x2 + |x – 1| = 1 is
(1) 1
(2) 0
(3) 2
(4) 3
Answer:
(3) 2

Explanation:
The given quadratic equatiuon is
x2 + |x – 1| = 1 ——– (1)

Case(i)
By the definition of mod function if x – 1 ≥ 0, then
|x – 1| = x – 1
∴ (1) ⇒ x2 + x – 1 = 1
x2 + x – 2 = 0
x2 + 2x – x – 2 = 0
x(x + 2) – 1 (x + 2) = 0
(x – 1)(x + 2) = 0
x – 1 = 0 or x + 2 = 0
x = 1 or x = – 2
Since x – 1 ≥ 0
x = – 2 is not possible. ∴ x = 1

Case (ii)
Again by the definition of mod function if x – 1 < 0 then
|x – 1| = – (x – 1)
∴ (1) ⇒ x2 – (x – 1) = 1
x2 – x + 1 = 1
x2 – x = 0
x (x – 1 ) = 0
x = 0 or x – 1 = 0
x = 0 or x = 1
Since x < 1, x = 1 is not possible
∴ x = 0
∴ The required solution set is {0, 1}
Number of solutions = 2

(2) 3x2 + 5x – 7 = 0
(3) 3x2 – 5x + 7 = 0
(4) 3x2 + x – 7 = 0
Answer:
(2) 3x2 + 5x – 7 = 0

Explanation:
The given quadratic equation is
3x2 – 5x – 7 = 0 ——— (1)
Let α and β be the roots of eqn (1)
Sum of the roots α + β = \(-\left(\frac{-5}{3}\right)\)
α + β = \(\frac{5}{3}\)
Product of the roots α β = – \(\frac{7}{3}\)
The quadratic equation whose roots are – α and – β is
x2 – (sum of the roots) x + Product of the roots = 0
x2 – (- α – β)x + (- α)(- β) = 0
x2 + (α + β)x + αβ = 0
x2 + \(\frac{5}{3}\) x – \(\frac{7}{3}\) = 0
3x2 + 5x – 7 = 0 is the required equation.

(1) 1, 2
(2) -1, 1
(3) 9, 1
(4) -1, 2
Answer:
(3) 9, 1

Explanation:
Given that 8 and 2 are the roots of the equation
x2 + ax + c = 0 ———- (1)
Sum of the roots 8 + 2 = \(-\frac{a}{1}\) ⇒ a = -10
Product of the roots 8 × 2 = \(\frac{c}{1}\) ⇒ c = 16
Also given 3 , 3 are the roots of

∴ The origin (0, 0) satisfies the inequality x + y < 6. Hence, the inequality x + y < 6 represents the half plane that contains the origin bounded by the straight line x + y = 6. Since x + y ≤ 6, this region contains all the points on the straight line x + y = 6.
Samacheer Kalvi 11th Maths Guide Chapter 2 Basic Algebra Ex 2.10 36
Thus the required region is the region common to 2x + y ≥ 8, x + 2y ≥ 8, x + y ≤ 6

The Seven Seeds Summary in English and Tamil

Long ago, there was a kingdom at the foothills of Anaimalai. The kingdom flourished in trade and arts under the rule of their king’s rule. He was respected and revered by all. It has been thirty years under his rule now. One day, the ageing king woke up worried. He was getting very old and had no heir to take his place. He decided to adopt and raise a child as the heir, but he knew that the adopted child must be honest.

வெகு காலத்திற்கு முன்னர், ஆனைமலையின் அடிவாரத்தில் ஒரு ராஜ்ஜியம் இருந்தது. அரசரின்ஆட்சியில் அந்த ராஜ்ஜியம் வியாபாரத்திலும் கலைகளிலும் செழித்தது. அந்த அரசர் அனைவராலும் மதிக்கப்பட்டு, மரியாதையும் செய்யப்பட்டார். அவர் அரசாள ஆரம்பித்து முப்பதுவருடங்களாகிவிட்டன. வயதான அந்த அரசர் ஒருநாள் கவலையுடன் எழுந்தார்அவருக்கு வயதாகிக் கொண்டே போவதாலும், வாரிசுகள் இல்லாததாலும் ஒரு குழந்தையை வாரிசாக தத்தெடுத்து வளர்க்க எண்ணினார். ஆனால் தத்தெடுக்கப்படும் குழந்தை நேர்மையாக இருக்க வேண்டும் என்பதும் அவருக்கு தெரியும்.

To find the child, he held a competition in his kingdom that was open to all. The competition had many levels and spanned for nearly six months. At the end of it, five boys and five girls made it to the very last round. There seemed little to separate them; each one of them was intelligent, strong and capable.

சரியான குழந்தையை கண்டுபிடிப்பதற்காக, எல்லாரும் பங்கேற்கக்கூடிய ஒரு போட்டியை அவர் நடத்தினார்.அந்த போட்டி, பல நிலைகளை கொண்டதாகவும், ஆறு மாதங்களுக்கு நீண்டதாகவும் இருந்தது. அதன் முடிவில், ஐந்து சிறுமிகளும், ஐந்து சிறுவர்களும் கடைசி சுற்றுக்கு தேர்வு பெற்றனர். ஒவ்வொருவரும் புத்திசாலியாகவும், வலிமையானவராகவும், தகுதிபெற்றவராகவும் இருந்ததால், தேர்ந்தெடுப்பது மிகவும் சிரமமாக இருந்தது.

The kina said, “I have one last test for you all. The one who passes this test will be the winner. As you all know the winner will be the heir to my throne.” He continued, “Our kingdom depends on agriculture, so the new leader must know how to grow plants. Here are seven seeds of wheat for each of you. Take them home. Plant and nurture them for six weeks. At the end of the sixth week, we shall see who has done the best job of nurturing them. That person will be the heir to the throne.”

“உங்கள் அனைவருக்கும் ஒரு கடைசி பரீட்சை உள்ளது, இதில் வெல்பவரே வெற்றியாளர் ஆவார்” எனக் கூறிய அரசர், “அவரே என் அரியணைக்குவாரிசு” என்றும் கூறினார். மேலும் “நம் ராஜ்ஜியம் விவசாயத்தை நம்பியுள்ளது, எனவே புதிய தலைவர்பயிர்களை பற்றியும்) வளர்ப்பது பற்றியும் தெரிந்திருக்க வேண்டும்” என்றார். “உங்கள் அனைவருக்கும் ஏழு கோதுமை விதைகளை அளிக்கிறேன். அவற்றை வீட்டிற்கு எடுத்துச் சென்று, நட்டு ஆறு வாரங்கள்பராமரிக்க வேண்டும். ஆறு வாரங்களின் முடிவில், யார்சரியாக அவற்றை வளர்த்து பராமரிக்கிறாரோ அவரே அரியணைக்கு வாரிசாவார்” என்றார்.

The children took their seeds and hurried home. They all got a pot, prepared some soil and sowed their seeds. The entire kingdom was excited. They were all anxious to see who the next king would be.

குழந்தைகள் விதைகளை எடுத்துக் கொண்டு வீட்டிற்குவிரைந்தனர். அனைவரும் ஒரு தொட்டியை எடுத்து,சிறிது மண்ணை இட்டு, விதைகளை விதைத்தனர். தமது அடுத்த அரசர் யார் என அறிய மொத்த ராஜ்ஜியமும் ஆவலாக இருந்தது.

One of the finalists was Ani. The days stretched into weeks. but the seeds failed to sprout. Ani didn’t know what had gone wrong. Ani and her parents were heartbroken. She had selected the soil with care, put the right manure, and very dutifully watered it. She had even prayed over it, day and night, and yet her seeds hadn’t grown at all.

ஓர் இல்லத்தில், அனி என்ற சிறுமியும் அவளுடைய பெற்றோரும் மனமுடைந்து இருந்தனர்.நாட்கள், வாரங்களாக நீண்டன. ஆயினும், விதைகள் முளைக்கவில்லை. தவறு எங்கே நேர்ந்ததென, அனி; க்கும் புரியவில்லை . ஏனெனில், சரியானபடி மண்ணை தேர்ந்தெடுத்து, சரியான உரத்தையும் இட்டு, கடமை தவறாது நீரை ஊற்றியும் வந்தாள். அவள் இரவும், பகலுமாக பிரார்த்தனை செய்து வந்தும்அவளுடைய விதைகள் வளரவே இல்லை .

Some of her friends advised her to go and buy new seeds from the market and plant. After all, they said, “How can anyone tell if they were the same seeds?”Ani’s parents had always taught her the value of honesty. They reminded her that if the king wanted them to plant just any wheat, he would have asked them to get their seed.

அவளுடைய சில நண்பர்கள் கடைவீதிக்கு சென்று புதிய விதைகளை வாங்கி பயிரிடும்படி கூறினர். ஏனெனில் யாராலும் விதைகளை குறிப்பாக அது, இது எனகண்டுபிடிக்க இயலாது. அனியின் பெற்றோர் அவளிடம் நேர்மையின் மதிப்பை பற்றி அவளுக்கு போதித்து இருந்தனர்.

“If you use anything different from what the king gave, that would be dishonest. I Maybe you’re not destined for the throne. If so, let it be, but it would be wrong to cheat the king,” they told her. Ani agreed.

அவர்கள் அனியிடம் “குழந்தைகள் ஏதாவது ஒரு கோதுமையைபயிரிடட்டும் என அரசர் நினைத்திருந்தால், அவர், விதைகளை நீங்களே ஏற்பாடு செய்து கொள்ளுங்கள் என்று கூறியிருப்பாரே” என்பதையும் அவளுக்கு நினைவுபடுத்தினர். “அவர் அளித்த விதைகளுக்கு மாறாக, வேறு ஒன்றை உபயோகப்படுத்தினால் அது நேர்மையற்ற செயலாகிவிடும். அரியணைக்கு நீ தேர்வாகாவிட்டாலும் பரவாயில்லை, ஆனால் அரசரை ஏமாற்றுவது தவறாகும்” என அவர்கள் கூற, அனியும்அதை ஏற்றுக்கொண்டாள்.

It had been six weeks now. The muchawaited day had come. The children returned to the palace, each of them proudly carrying a pot of healthy seedlings. It was obvious that the other nine had great success with their seeds.

ஆறு வாரங்களும் முடிந்துவிட்டன. எதிர்பார்க்கப்பட்ட நாளும் வந்தது. குழந்தைகள் அனைவரும்அரண்மனைக்கு திரும்பினர். ஒவ்வொருவரும் கையில் ஆரோக்கியமான பயிர்களை, தொட்டியில் வைத்திருந்தனர். இதன் மூலம் (அனியைத் தவிர மற்ற ஒன்பது பேரும் தங்கள் விதைகளை நடவு செய்வதில் வெற்றியடைந்திருந்தனர்.

The king arrived. He was beaming looking at the children and their pot of healthy seedlings. He began walking along the line of pots the children had kept. He asked each of them, “Is this what grew from the seeds I gave you?” And each of them responded, “Yes, your majesty.” And the king would nod and move down the line.

அவைக்கு வந்த அரசர், குழந்தைகளின் தொட்டிகளில் ஆரோக்கியமான பயிர்கள் இருப்பதை கண்டு புன்னகைசெய்தார்! குழந்தைகள் வரிசையாக வைத்திருந்த தொட்டிகளை பார்வையிட்டவர், ஒவ்வொருவரிடமும் “நான் கொடுத்த விதைகளிலிருந்தா இவை வளர்ந்தன?” என்று கேட்டார். ஒவ்வொருவரும் “ஆம், மாட்சிமை பொருந்திய அரசே” என கூறவும், அரசர் தலையசைத்து சென்றார்.

Samacheer Kalvi 4th English Guide Term 3 Prose Chapter 1 The Seven Seeds

The king finally got to the last one, Ani. The girl was shaking. She feared that the king might have thrown her into prison for wasting his precious seeds. “What did you do with the seeds I gave you?” the king asked. “Your majesty, I planted them and cared for them every day. I am sorry but, they failed to sprout,” Ani said. She hung her head in shame. “Boo!” jeered the crowd.

கடைசியாக இருந்த அனியிடம் அரசர் சென்றார். அந்த சிறுமி நடுங்கிக் கொண்டிருந்தாள். அரசர்கொடுத்தமதிப்புமிக்க விதைகளை வீணாக்கிவிட்டதற்காக, ” தன்னை அரசர் சிறையில் போட்டுவிடுவாரோ என அவள் பயந்தாள். “நான் கொடுத்த விதைகளை நீ என்ன செய்தாய்?” என அரசர் அவளிடம் கேட்டார். “மாட்சிமை பொருந்திய அரசரே, நானும் விதைகளை பயிரிட்டு தினமும் பராமரித்தேன். ஆனாலும் அவை முளைக்கவில்லை என்பதற்காக வருந்துகிறேன்” என்று அனி கூறிவிட்டு தலையை கவிழ்த்துக் கொண்டாள்.கூடியிருந்த கூட்டமும் அதற்கு தன் அதிருப்தியைக் காட்டியது.

But the king raisedhis hands and signalled for silence. Then he said “Dear people behold my heir. The next leader of our kingdom!” The people were confused, “Why that girl? How can she be the right choice?”

தன் கைகளை உயர்த்தி கூட்டத்தினரை அமைதியாக இருக்கும்படி சைகை காட்டிய அரசர், அன்பு மக்களே,இதோ நம் இராஜ்ஜியத்தின் அடுத்த தலைவர்” எனக் கூற மக்கள் குழப்பமடைந்தனர். “யார் இவளா? எப்படி இவள் சரியான தேர்வாக ஆனாள்?” எனக் குழம்பினர்.

The king took his place on his throne with Ani by his side and said, ‘I aave each of them, seven seeds. This test was not for growing wheat. It was a test of character, a test of honesty. If a leader must have one quality, it must be that he or she should be honest. People should be able to trust the leader. Only this girl passed the test. I gave boiled seeds and boiled seeds cannot grow.”

தன் ஆசனத்தில் அமர்ந்த அரசர், அனியை தன் அருகில் அமர்த்திக்கொண்டு இவ்வாறு கூறினார். “நான்ஒவ்வொருவருக்கும் ஏழு விதைகளை கொடுத்தேன். இது கோதுமை விளைவிப்பதற்கான போட்டியல்ல. இது குணத்திற்கும், நேர்மைக்குமான பரீட்லைகுணத்திற்கும், நேர்மைக்குமான பரீட்சையாகும். ஒரு தலைவர் யாராக இருப்பினும் அவருக்கு வேண்டிய தகுதி, அவர் நேர்மையானவராக இருக்க வேண்டும்என்பதே. மக்கள் நம்பும்படியாக தலைவர் இருக்க வேண்டும். அந்த தேர்வில் இந்த சிறுமியே தேறினாள். நான் (அவர்கள் அனைவருக்கும்) கொடுத்தது, வேகவைத்த விதைகள். அவை எவ்வாறு வளரும்?”.
