Confused

Hello, I can not tell the difference between answer choice C and D. I chose C but I can see how D can be right too.

Check the wording, they tricked you by leaving out the specific grade of B minus. In the question it says "lower than a b minus" c says "higher than b minus", and e correctly stated "b minus or higher".
So imagine "most" in the question was 55%, and 7% of the people in the class got a b minus (plausible), then C is wrong, and E is still right.
Don't fret, i only got 2 wrong this entire section, and this one was one of them...so it's a tough question...

@shylahmarieg@gmail.com,

Happy to help.

@Deke, great participation and analysis. Keep up the hard work!

Let's look at (C), (D), and (E). However, before we do, let's look at
the stimulus. We're looking for the answer that we can infer based on
the information we've been given. This is essentially a must be true
question. When doing this question, I actually predicted the correct
answer before looking at the answer choices by forcing myself to infer
what I could from the facts that we've been given.

We know that most of the students who took Spanish 101 went to every
class. We also know that if someone got a grade lower than B minus,
they didn't go to every class. What does this mean? Well, let's think
about it. If most kids went to every class, and if kids who got below
a B- missed at least class, then this means that most kids in the
class had to have gotten a B- or better in the class because most kids
didn't miss a single class.

(E) says, "More than half of the students received a grade of B minus
or higher."

"More than half" means "most," so (E) is saying exactly what we
anticipated the correct answer saying. When we combine the facts, this
is the inference we can make, so (E) is the correct answer choice.

(C) says, "Most of the students received a grade higher than B minus."

As @Deke mentioned, the stimulus discusses kids who got lower than a
B-. The negation of this is B- or higher. We do know that most of the
students got a B- or higher, not that they received grades higher than
B-. Maybe most of them actually got B- grades. Because of this, (C) is
out.

(D) says, "At least one student who received a grade of B minus or
higher missed one or more class sessions."

The problem with (D) is that it's possible that all of the students
who got grades of B- or higher had perfect attendance. We don't have
enough information to know for sure, so (D) is out.

Does this make sense? Let us know if you have any more questions!
