The correct answer is option 4 i.e. at least 43 people killed.

• In the given sentence passive voice ‘were killed’ will be used in place of ‘killed’ because the given sentence means that the people were killed and not that people killed someone else.

• Hence, people received the effect of the verb i.e. kill.

So, the correct sentence will be: At least 43 people were killed in a fire that broke out in a house at Anaj Mandi on Delhi’s Rani Jhansi road early Sunday morning.

The correct answer is option 1 i.e. By the time the delegation arrived, the experts had already compiled a comprehensive report detailing the catastrophic effects of deforestation on biodiversity.

The sentence shows two consecutive events of the past.

For the former action: Past perfect tense i.e. Had + V3

For the following action: Simple past tense i.e. V2

According to the sentence, the report was created first and then the delegations arrived.

So "had already created" and "arrived" should be used.

The correct answer is option 1 i.e. and recognized Jerusalem as the Israeli capital.

The use of the verb ‘recognized’ in the given sentence is wrong.

In the given sentence the preposition ‘to’ is used for ‘overturn’ as well as for ‘recognize’.

When the same preposition is to be used for two verbs one is before the ‘and’ and another is after ‘and’, then the preposition is used only with the verb before ‘and’.

Hence, in the given sentence ‘recognize’ will be used because V1 is used after ‘to’.

So, the correct sentence will be: Mr. Trump opened his speech by talking about his decision to overturn long-standing American foreign policy and recognize Jerusalem as the Israeli capital.

The correct answer is option 4, i.e. as high as.

The phrase must be replaced with ‘as high as’ since ‘as high as’ is used to ‘to emphasize an amount/price’.

Since there is a discussion of the rent of the house, ‘as high as’ will be used.

The word "as" after "as high" represents a comparison of data with some other thing.

Hence, the chosen option is correct.

The correct answer is option 3 i.e. needn’t have bought.

Explanation:

The sentence implies that the subject is asking the person not to get such an expensive gift and we use 'need not' to show that.

So, ‘needn’t have bought’ will be the correct phrase to replace ‘need no buy’.

Hence, the chosen option is correct.

The correct answer is option 2, i.e. no improvement.

1. Option 1, seeing will appear right after 'going' and two verbs in their continuous tense cannot appear consecutively in a sentence unless we use commas to express something different, unlike the given sentence.
2. Option 2, no improvement is the correct answer as all the other given options are grammatically incorrect.
3. Option 3, to saw is incorrect. The correct way to write it is 'to see' which denotes a present tense. 'Saw' can appear after first/second/third persons or after nouns to indicate past tense.
4. Option 4, to seeing is wrong because only 'see' can appear after 'to'. 'Seeing' changes the tense and hence will require more parts of speech, such the verb 'be'.

The correct answer is option 2 i.e. Agitated.

• In the given question, we need to select the SYNONYM of the given word.
• A word that has the SIMILAR meaning of another word is its synonym.

Let's have a look at the meaning of the underlined word:-

• Distraught means "extremely worried, nervous, or upset".
• Synonym of distraught is 'agitated' which means worried or angry.

The chosen option expresses the nearly similar meaning of the given word hence, it will be the correct choice.

The correct answer is option 2 i.e. Ridicule.

Admire means to like or appreciate/praise something. The opposite of it will be to dislike or mock something.

Hence, Ridicule is the correct answer.

The correct answer is option 2 i.e. Lenient.

Antonym: a word opposite in meaning to another.

Stern means very serious.

Lenient is the correct antonym that means not as strict as expected.

Meaning of other words:

Flippant: not serious enough about things.

Desolate: very unhappy.

Noxious: harmful.

The correct answer is option 2 i.e. To the best of one’s ability.

The phrase "to the best of one’s ability" means doing something as well as possible, which fits perfectly with the meaning of "replied as well as was possible for anyone in the situation."
