Algebra Book Chapter Problem Sets - Lack of answer choices?

by athenalux Tue Jul 14, 2015 9:17 pm

Does anyone else seem to be missing possible answer choices to questions in the problem sets?

For example, according to the Algebra Guide 1 Chapter 3 Problem Set Solutions, the answer to question # 11 is (D).

Yet, on my Problem Set page, question 11 doesn't have a (D) answer choice. In fact, no answer choices at all are listed. The formula is provided (x^2 - 2x -15 =0), as well as Quantity A and Quantity B, but no (A), (B), (C), (D) answers.

Questions 12 and 13 do not have possible answer choices listed either.

Any explanation to this situation or helpful information would be extremely appreciated.

Thank you!

Hey Athena,

Uh-oh. You need to go back to the beginning of your studies! These are called Quantitative Comparison questions. They make up a significant portion of the quant section of the GRE. They have four answer choices: A, B, C, and D. They always mean the same thing.

A - Quantity A is always bigger
B - Quantity B is always bigger
C - The two quantities are equal
D - The relationship cannot be determined

If you don't have our QC book, I'd recommend picking it up! :)
