Answer with Explanation

Ans (2): but if someone asks a wave question, it ought to give a wave answer

It is a fragmented sentence or we can say a comment. Here Abdul Kalam Azad is explaining about the nature of a particle, and not emphasizing something. So, the error is in part 2 as in the sentence instead of ought to, we must add it will, as it emphasize something which has to happen.

Ought to is a model verb while ‘will’ is an expression of the future tense.

The correct sentence will be ‘Abdul Kalam Azad in his autobiography explained if someone asks a particle question, it will give a particle answer, but if someone asks a wave question; it will give a wave answer through the proper description and the interplay of our goals’.

Answer with Explanation

Ans (3): is due to fact that

If you read the sentence carefully, you will find that something is missing. It is a definite artice ‘the’. Article ‘the’ is used in front of the noun, to express something a speaker is absolutely about. This makes part 3 of the sentence wrong.

The correct sentence will be ‘Why I have not been able to pay our rent on time is due to the fact that I had not yet received my salary’.

Answer with Explanation

Ans (3): a number of colourful frames was displayed

The sentence is in the past tense, so we need to check whether a subject is singular or plural. We take a singular verb if the subject is singular else we opt for a plural verb. In the second part of the sentence, it is clearly mentioned that there were not one or two but many colourful frames, here the error is in sentence 3. Instead of was we should add were.

The correct answer is “When I went to the market, I saw a number of colourful frames were displayed in the store window”

Answer with Explanation

Ans (4): and this hamper their daily life

The sentence is not singular but plural. Many Indian suffers. Verb agreement with complex subject can be complicated as many times simple subject is singular, but we have to use another plural noun for modifying the simple subject.

Error is in part 4 of the sentence

The correct sentence is “During my visit to India I observed that most of the Indians suffer because they are incapable to control their emotions, and the hampers their daily life’.

Answer with Explanation

Ans (2): or is fascinated by the project

In this sentence, the conjunction is wrongly used. Correlative conjunctions are neither, nor, either, and, and or Conjunction neither is always followed by nor. In the same way, either is followed by or. So, the error is in part 2 of the sentence.

So the correct sentence will be, ‘He neither has enough time nor is fascinated by the project, as he is running his own business, which often takes him out of the station’.

Answer with Explanation

Ans (1): He was to about say something

‘to’ will be used after ‘about’ because “Subject + To be (is/am/are/was/were)+about+to+V1” is ideal sentence structure. For example: He was about to leave for office.

Answer with Explanation

Ans (4): On dissident republicans
