AFTER LOOKING AT IT AGAIN,,,,,,THE IDIOM IS REQUIRED TO....SO PAUL MAY BE CORRECT HERE...AS TO SURVIVE IS COMPLETELY WRONG...

paul:

REGARDING THE THIRD QUESTION, IT IS AN OG QUESTION AND I DID IT JUST YESTERDAY..AND I ALSO SELECTED THE SAME B AS THE ANSWER BUT IT IS WORNG, BUT I STILL COULD NOT UNDERSTAND THEIR EXPLAINATION...

paul:

CAN U EXPLAIN WHY E IS CORRECT IN THE SECOND QUESTION....
AND WHY NOT OTHERS.....

I by no means want to imply that my answer is correct, far from there. Actually, as you are bringing it up, I think D makes more sense now. E uses a passive form which is not ideal on the GMAT. I originally took E because it seemed more clear that "but many of them can be harmful to health, especially if they are used improperly." "them" and "they" refered to the main clause's subject, "household products". Upon re-analysis, I can now say with confidence that D's active form is more concise. Furthermore, in D, "a consumer" singular form makes it clear that "them" and "they" both refer to the plural form "household products"

So final answers should be B,D,C,B

I like B.

The energy source ........is not a nuclear reactor,............, but rather....

Thats how i see it.

D for survival is the best option here.
D even though may not is introduced, idiom is still think of X as Y. Ignore the not part if it confuses you. D is best here. E distorts the idiom.
C: we need WAS for the singular The Adventures of Huckleberry Finn.
B: Not X but rather Y
