can someone explain how the OA is A. i chose B just as majority of those who answered also chose B but it turns out that B is wrong

Hi gvvsnraju@12!

Carolyn from Magoosh here -- I can step in for Mike

Choices A and C are very similar:

A) No funds obtained through the Education Surcharge on gasoline can be utilized for any other purpose, unless the amount far exceeds those (amounts) that are necessary to fully satisfy all the education programs.

C) No funds obtained through the Education Surcharge on gasoline can be utilized for any other purpose, unless the amount far exceeds those (amounts) necessary to fully satisfy all the education programs.

In both of these, "those" is correctly in parallel with "the amount". The only difference between the two options here is the extra "that are" following "those" in option A. The "that are" makes choice A clearer, and therefore a better option, than choice C. It specifies which "amounts" we're talking about -- it tells us that "those (amounts)" are the amounts that are necessary to satisfy the education programs. While the meaning still comes through in choice C, it isn't as explicit. So A is the better choice

Hope that helps!
