I am asking this question because I have seen that OG clearly explains that an answer choice is wrong because " and also" is redundant. However, I have also seen the appearance of " and also" in their own words. I mean they write things with this phrase but at the same time say it is redundant in the explanations( which means it is not the right usage?). The same case is for" comma, which". I studied some grammar prep book saying "comma, which" cannot refer to the preceding clause in the GMAT. Is that true?
In addition, for some other OG problems, some choices include " and also' but this time OG says NOTHING about it. Does it mean it is generally ok to use " and also"? I am really confused.
So "and also" is definitely wrong? Whenever you see it appear in the answer choice, you should eliminate that choice? Or it is just redundant but grammatically
right and we should keep it as the right answer if no other better choices appear?
Thanks a lot!
You're currently using the wrong definition of "wrong". In SC, an option is correct if it is the
best of the 5 options (it doesn't have to be perfect).
Although the correct option needs to be grammatically correct, concepts like redundancy do not lead to a yes/no decision in isolation. You
must consider the other options before removing an option on the basis of redundancy.
