The phrase ‘almost terrible as’ needs to be replaced with ‘almost as terrible as’ to make the sentence correct. This is because, ‘As...As’ is the pair of words that needs to be used together. Thus, the correct sentence would be, ‘For young Donald, peace in Vietnam was almost as terrible as war’.

'Are’ needs to be replaced with ‘is’ to make the sentence contextually correct. This is because, ‘in subject verb agreement, we match the subject with the nearest verb or the verb with the nearest or the first subject. But the verb should be matched with the main subject of the sentence’. Here the main subject is ‘Ignorant’ which is singular and so is followed by a singular verb.

If some action has started in the past and is still continuing, then present perfect continuous tense should be used instead of present continuous tense. So, the phrase ‘am living’ needs to be replaced with ‘have been living’ to make the sentence contextually correct. Thus, the correct formation would be, ‘I have been living in Bombay for the last ten years’.
