Hi,
Following sentences I came across magazine kindly clear my doubts. Please note that it's better to say 'answer my questions' rather than 'clear my doubts'.
1. The annual earnings have be pegged at $3.86 billion. In the above sentence we are speaking about a annual so should it be the annual earnings has been pegged.. No, earnings is treated as a plural word.
2. Vir Sanghvi, reputed as one of the youngest editor(or editors) in the Indian media terrain. 'Editors', because you are saying 'he is one of a group'. This sentence is not correct. For example, it has no main verb.
3. The country is witnessing a sea change in the lifestye, mindset, aspirations and attitudes of its people. In the above sentences it aspirations..attitudes but then mindset and lifestyle are singular without 's' is any structural error or if I add 's' to all the words(i.e including lifestyle & mindset) then is it will be wrong please explain I'd make all these words plural, because you are speaking of so many people.
4. No one should suffer because he happened to be born in a certain race, class or economics condition. (is using economics conditions in the end will be wrong) It's OK, but say the singular 'economic condition'. If you are making a general statement that is true for past, present and future, it's better to say 'happens' rather than 'happened'.
5. Everything about Crompton Greaves is (a) world class. (aticle should come or it can be omitted) You need to omit it. The phrase is used adjectivally.
Best wishes, Clive
