Posting my notes for when I get it right or wrong. Just started today, Thankfully, this one went well. Hopefully my notes help maybe 1 person.

First, I believe the hypo is saying: "Most of the total # of students in Spanish 101 attended every class session. But, each student who got lower than a B- missed 1 or more classes  (their would be in the minority of the total # students)

Rules:

MAJORITY GROUP

• B- or higher ->> Never missed a class

  • B+ ->> never missed

  • A -/+ ->> never missed

MINORITY GROUP

• Lower than a B- ->> missed 1 or more classes

Answer A: Some students who received A- or higher attended every class session (Fails to meet the majority group conditions. It would need to be all of them.

Answer B: "Most if not all" = "The vast majority" who missed at least 1 class got lower than a B-. Wrong, everyone got lower than a B- if they missed at least 1 class.

Answer C: The answer parallels the logic of the majority

Answer D: At least (can be more) 1 student (can be more than 1 student) -- who got a B- or higher missed one or more class sessions. That doesn't make any sense.

Answer E: More that 50% of the # of students got a B- or higher. Hm.... "most of the student.... every class" "however...." does the however imply less than 50%? I think so. Ah, I see, in contrast to answer C, it specifies both the B- and above. Question C scopes in on all grades above B-. Meaning, the answer is E.
