Sir, see this question,pls.
people(who're) involved, people (who're) concerned ======= related people?
I don't know when i can eliminate (who're) in my essays.
Eg: There is a beautiful girl (who is) flirted by someone. Or ......girl (who is) regareded as a hot chick.
They are just what i take for example. I'm always not sure how to eliminate (who, which, what, etc. as well as (is, are, be))
And there is another question:
eg. Female smokers saw the opposite trend. They increased from 16% in 1960 to 24% in 2000.
Can I change it to " .......trend, who increased .....?
Sometimes I'm at a lost about such organization of sentences, because I don't know their differences except one sentence or two sentences.
Pls tell me know. Thank you.
