The correct answer is "Option 3'.

Key Points

• In indirect speech, we report what someone said without using their exact words. The key points to consider when converting direct speech to indirect speech are:
• Pronouns: The pronouns need to be changed to reflect the perspective of the speaker in the reporting clause.
• In this case, since the student is speaking, the pronouns "I" and "her" need to be changed accordingly.
• The options that use "he/she" are correct in this regard.
• Tense changes: The tense of the verb in the reported speech needs to be shifted back.
• The verb "do not remember" in the direct speech should be changed to "did not remember" in the past tense in the indirect speech.

Therefore, the correct sentence is: 'The student told her that he/she did not remember her name.'

Additional Information

• Now, let's examine why the other options are incorrect:
  • Option 1 is incorrect because it uses "I" in the reported speech, which doesn't match the perspective of the student who is speaking.
  • Option 2 is incorrect because it uses "cannot remember" in the reported speech, which doesn't match the tense of the original statement.
  • Option 4 is incorrect because it uses "do not remember" in the reported speech, which doesn't match the tense of the original statement.

The correct answer is 'might'.

Key Points

• In this context, 'might' is used to express a possibility or uncertainty.
• 'Will' would suggest certainty, which contradicts the fact that he has not worked hard.
• 'Can' refers to ability, not to possibility in this context.
• 'Do' is not a modal verb and is not used to express possibility.

Therefore, the correct answer is Option 2.

The correct answer is 'urging'.

Key Points

• The word 'Prodding' means stimulate or persuade (someone who is reluctant or slow) to do something (किसी ऐसे व्यक्ति को उत्तेजित या राजी करना जो कुछ करने के लिए अनिच्छुक या धीमा हो)
  • Example - They attempted to prod the central bank into cutting interest rates.
• The word 'Urging' means the act of strongly advising or encouraging someone to do a particular thing (किसी को किसी विशेष कार्य को करने के लिए दृढ़ता से सलाह देने या प्रोत्साहित करने की क्रिया)
  • Example - With their dad's urging, the girls started playing football.
• Thus, the word 'prodding' means 'urging'.

Hence, the correct answer is option (3).

Additional Information

• Let's explore the meaning of other words:
  • sermonising: deliver an opinionated and dogmatic talk to someone (किसी से एक राय और हठधर्मिता की बात करें)
    • Example - She's a teacher who can talk to her students about serious subjects without sermonizing.
  • torturing: cause great mental suffering or anxiety to (बड़ी मानसिक पीड़ा या चिंता का कारण)
    • Example - She was tortured by grief.

The correct answer is: 'a little of'.

Key Points

• 'A little' is means not much. It is used in affirmative sense.
  • Ex. I enjoy a little sugar in my coffee.
• The context of the sentence tells us that the person ate only a small amount of the soup because it was very spicy.
• So, 'a little of' is the most suitable to fill in the blank.
• Here, preposition 'of' will be used as it is followed by an object.

Hence, the correct sentence is: The soup was very spicy so I only ate a little of it.Additional Information

• 'Little' means not much. It is used in negative sense.
  • Ex. I have got little money left in my wallet.
• 'The little' means not much but all.
  • Ex. The little she did for me was very helpful.

The correct answer is 'after'.

सही उत्तर 'बुढ़ापा' है।

Key Points

• 'बुढ़ापा' शब्द पुल्लिंग है।
• स्पष्टीकरण- उसका अब बुढ़ापा आ गया है- इस वाक्य से स्पष्ट होता है कि 'बुढ़ापा' पुल्लिंग शब्द है,
• 'बुढ़ापा' आ गयी है- ऐसा कहना अनुचित होगा क्योंकि 'बुढ़ापा' शब्द का प्रयोग स्त्रीलिंग में करना वाक्य को गलत कर रहा है।

अन्य शब्द स्त्रीलिंग हैं।

'दया' आयी, 'सुबह' हो गयी, 'अध्यापिका' कक्षा से बाहर चली गयीं। इन वाक्यों से स्पष्ट होता है की 'दया', 'सुबह' और 'अध्यापिका' स्त्रीलिंग के रूप में प्रयुक्त किये जाते हैं।

The correct sentence is: My teacher said to me, "If you don't work very hard, you may fail the end-term exam."Key Points

• There are a few rules to remember when changing a sentence from indirect to direct speech.
  • ​​When the reporting verb is in the past tense in indirect speech, the tense of the sentence in direct speech will change.
  • The given sentence is in the future conditional tense in the indirect speech so it will change to the present conditional tense in direct speech.
  • We use modal verbs to express emotions such as permission, possibility, and certainty in a sentence.
  • The modal verb 'might' in indirect speech changes to 'may' in the direct speech of the given sentence.
  • Also, 'didn't work very hard' should be changed into 'don't work very hard'.
  • The first person pronoun "I" in indirect speech changes to the second pronoun person "you" in the direct speech of the given sentence.

The correct sentence is: My teacher said to me, "If you don't work very hard you may fail the end-term exam."

Hence, the correct answer is option 3.

Checking Statement I:

Code for the word dove cannot be found.

Hence data in statement I is sufficient to answer the question.

Checking Statement II:

Code for the word dove cannot be found because it is not mentioned in statement II.

Hence data in statement II is sufficient to answer the question.

Checking Statement both statements I and II together:

The code for dove is 'hv'.

Hence data in statement I and II together is not sufficient to answer the question.

Hence option D is correct.

Hydrological Cycle

• The process of circulation of water within the hydrosphere of Earth in different forms such as liquid, solid and gaseous states are called the Hydrological Cycle of water.
• It starts with the Evaporation of water from the surface of the water bodies and further, it includes Transpiration, Sublimation, Condensation and Precipitation.

'Hydrological cycle' steps

• The first step of the water cycle is evaporation from water bodies means the part of the Hydrosphere.
• The second step of the water cycle is condensation, which takes place in the atmosphere.
• The third step of the water cycle is precipitation and runoff means the part of the lithosphere.
• The final step of the water cycle is in the Biosphere. 
• It is the zone where all the spheres interact and work together.
• It includes processes like water uptake and transpiration by plants.

​

Thus, in the 'Hydrological cycle' the order of the source in which they connected from each other is first Hydrosphere, second Atmosphere, third Lithosphere and fourth Biosphere.

Additional Information

Processes during a hydrological cycle:

​​Evaporation

• When waters convert from liquid to gas stage as it moves from the groundwater into the atmosphere, this phenomenon is called Evaporation.
• Mainly Solar radiation is the source of energy for evaporation. 

Transpiration

• When plant uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

Condensation

• The Process of conversion of water vapour to liquid water droplets in the air is called Condensation.
• It is responsible for the formation of fog and clouds.

​Precipitation

• When the condensed water vapour falling to the surface of the Earth is known as Precipitation.
• It occurs in the form of rain, snow, and hail.

Key Points

Trees as a shelter for animals:

• Trees provide shelter and food for a variety of birds and small animals, such as squirrels and beavers.
• Enhancing growth diversity, trees create an environment that allows the growth of plants that otherwise would not be there.
• Flowers, fruits, leaves, buds, and woody parts of trees are used by many different species.
• Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. 

Deforestation can lead certain tree species to permanently disappear, which affects the biodiversity of plant species in an environment.

Hence, the reason is also correct.

Important Points

Human activities that influence the extinction and endangerment of wild species fall into a number of categories:

• ​Land use practices like Deforestation, Projects in urban and suburban development, agriculture, and water management projects that encroach upon and destroy natural habitats.
• Unsustainable hunting and harvesting result in higher rates of death than new individual recruitment.
• Ecological damage caused by water, air, and soil pollution.
• Anthropogenic (human-caused) global climate change.
• ​According to the India State of Forest Report (ISFR) 2019, The forest and tree cover in the country is estimated at 80.73 million hectares, which is 24.56 percent of the total geographical area.​
