Hello deepti_bagga,

I'm afraid I don't understand your question. I can see that this is a transformation exercise but I don't understand what you are trying to do. We will be happy to try to help but you'll need to explain it a little more clearly. Also, please try to post your question on a related page, rather than just any page. This will help others to find your question and our answer, which may be of use to them.

Hello, wanted to ask about third sentence. Why it is using "gets", as I understood the sentence time is present simple = -s ending only adds to he/she/it. Or it is some another rule for this expression?

And wonder about 6th sentence . Can I use instead of "this holiday" - these holidays. Or that would be incorrect?

Hello DiaLuna,

In 3, 'gets' is indeed the verb in a third-person singular form, which means that the answer, i.e. the subject of the verb, must be 'one'. This third-person singular form is used not only with the subjects 'it', 'she' and 'he' - it is used with any singular subject that is not 'I' or 'you'.

In 6, you could say 'these holidays' if you were referring to more than one holiday. If you did this, then the answer would of course be 'ones' instead of 'one'.

Please explain this point: If we have 6 pens and I want to ask "which one of these pens are red? Should I use plural noun and verb like "these pens " and "are"?or use singular N and V and ask "which one of this pen is red?" and also if instead of pen we have pants which form of question should be used?

Hello shadyar,

In the case of pens, the correct sentence is 'Which one of these pens is red?'. The singular verb 'is' is used because it is essentially a question about one pen ('which one'), i.e. one pen among many.

'pants' is grammatically plural, whether it refers to one item of clothing or many. Since it can be ambiguous, we often speak about 'a pair of pants' to refer to one item of clothing - note that since 'pair' is grammatically singular, singular verbs are used. So you could say 'Which pants are red?' or 'Which pair of pants is red?'
