In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed, choose 'No improvement'. Coming here uninvited wasn't a good idea - you must have thought about it more carefully. A. should have B. have to C. ought have Correct Answer Only A
The sentence uses the form ‘must have’ which is incorrect and needs to be improved.
We use 'must’ when we want to say that it is necessary or very important that something happens in the present or future. The auxiliary verb 'should’ which is used to give recommendation or even an opinion has to be used in the sentence. You should have... = you made a mistake/you did something wrong. Only choice A is correct.
Choices C and B are incorrect as they make the sentence grammatically wrong. ‘Ought’ expresses ideas such as duty, necessity and moral obligation.
Hence the correct answer is option 2.
