Studies of test scores show that watching television has a markedly positive effect on children whose parents speak English as a second language, as compared to those whose native language is English.
A to those whose native language is English
B with children whose native language is English
C with those who are native English speakers
D to children whose parents do not
E with children whose parents are native English speakers
Can any one suggest why is A wrong
Those is a possessive pronoun should refer to preceeding noun in number which it is refering to parents and should logically refer to.
E is more wordy though its straight fwd.
I always mess up with Comparisons.... Pls suggest me whats wrong in my approach.
