sentences improvement section 2 Detailed Explanation And More Example

Answer: (a)

When two actions are in the past tense, first action is expressed in past perfect tense i.e. had + past participle of be (been)

Answer: (a)

The real intention of writing the given sentence is to express a hope that he will become successful in the forthcoming examination, ie, he will prove his merit. Therefore, for the phrase written in bold the correct alternative is given in (c). Now, let us consider other options also for their validity.

After ‘be’ V₃ is used, but, in option (b), after ‘be’ V₁ has been used. Therefore, this option is ruled out. Option (a) has ‘will have to prove’ which means he is bound to prove, but the real intention is to express a 'hope' not a binding.

Therefore, (a) cannot be a correct choice. Now, when option (d) is placed in place of the phrase in bold, the sentence becomes a mixture of present and past tense. Such type of structure is not preferred. Hence, reject it.

Answer: (b)

Answer: (a)

Answer: (c)

First of all let us know the meaning of all the phrases used here.

Look at = to examine something closely; to think about; to consider

Look about = to try to locate someone or something.

Look in = to make a short visit to a place; especially somebody’s house when they are ill/sick or need help.

Look into = to enquire into something.

Now, it is clear that ‘at’ should be replaced with ‘into’.

Answer: (c)
