In light of the part I have made bold I still feel E should be the answer

If a student in the Business program described above took a seminar on Microeconomics but did not take a seminar on Applied Economics, which of the following must be true?
In C
C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1995.

There is no information given in the argument about requirements of an international MBA student prior 1990. Hence the must criteria will not be satisfied by C

No man, you're still mixing it up. The must criteria are completely satisfied by C. The must criteria is NOT satisified by E. If the candidate in question entered the program prior to 1990, he could have chosen to take Microecon and chosen not to take Applied.

If he didn't take the Applied seminar, then he could not have entered the program after 1994. Period.

If he took the Micro seminar, that does not automatically mean he took it because it was required. Look at it like this:

Entered program in:

1995 - He takes Micro and Applied because they are both required.
1993 - He takes Micro because it's required. He doesn't take Applied because it doesn't interest him.
1985 - He takes Micro because it interests him. He doesn't take Applied because it doesn't interest him.

Late response but it has to be E!

E - choice clearly boundaries the input conditions

Ok, this is my last stab at this.

Imagine this were the question:

In the Business program at a university, all candidates for the MBA in International Business who entered the program after 1990 took a seminar on Microeconomics.

If a student in the Business program described above took a seminar on Microeconomics, which of the following must be true?

A. The student entered the Business program prior to 1990.

B. The student entered the Business program after 1990.

C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1990.

D. If the student was a candidate for the MBA in International Business, then the student entered the program after 1990.

E. None of the above.

If you did not answer E, you are wrong. Just because you take a course in Microecon does not mean you entered the program after 1990. We know that if you entered the program after 1990, you must have taken a course in Microecon. We DO NOT know if the reverse is true. A student who took microecon could have entered the program at any time. All we know is that, if he had entered the program after 1990, he would have been required to take microecon. If he had entered prior to 1990, he would not have been required to take microecon, but he could have taken it if he had wanted to.

I'll try and come up with an analogous question:

In the NFL Hall of Fame, since 1995 all candidates for induction had played in the league for a minimum of 7 seasons. Since 2000, all candidates had played in the league for a minimum of 9 seasons.

A Hall of Fame inductee has been selected at random. He played in the NFL for 8 seasons. Which of the following must be true?

(A) He became a candidate for induction to the Hall of Fame before 1995.
(B) He became a candidate for induction to the Hall of Fame after 1995.
(C) He became a candidate for induction to the Hall of Fame before 2000.
(D) He became a candidate for induction to the Hall of Fame after 2000.
(E) He became a candidate for induction to the Hall of Fame after 1995 but before 2000.

The answer is C. All we know is that the guy did not play in the league for more than 9 seasons. Therefore he could not have been up for indiction after 2000, because all the candidates that went up for induction after 2000 had played for at least 9 seasons. Therefore he must have been a candidate for induction before 2000.

Do we definitively know whether he was a candidate for induction after 1995? No. Just because he played more than 7 seasons in the league does not mean he was inducted after 1995. We know that all the players who actually WERE candidates after 1995 played more than 7 seasons, but it is also very possible that prior to 1995 there could have been players inducted who had played for at least 7 years. So we don't know anything about whether he was inducted prior to 1995.

As a last word, it's like the "All squares are rectangles. A randomly selected quadrilateral is a rectangle. Is it a square?" question.

Alright that's my last stab at it yall. Good luck.

As I went on reading the choices, I found E is better than B.

HI guys, I have a very different doubt...
A says that the student entered the business program prior to 1995, and C also says the same thing.
Isn't it implied, that the student theyare talking is student of MBIM????
I thinkthat it should be implied.

what is the OE for this?
Not sure how the OA can be C.

C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1995. - if this is true, what if the student entered the program in 1994.

C according to me.

Necessary --> Sufficient
Premise 1: 1990+ --> Microeconomics. Contrapositive : ~Microeconomics --> ~1990+
Premise 2: 1994+ --> Applied Economics. Contrapositive ~Applied Economics --> ~1994+
Conclusion: Microeconomics
~Applied Economics

We can only conclude ~Applied Economics --> ~1994+ (from contrapositive of Premise 2).
Taking Microeconomics, does not guarantee that student graduated after 1990 (Invalid Reasoning).

why can't it be E.

Think E is more precise in considering after 1990 & prior to 1995

I also thought it was E. Kaplan gave the same reason for why it can't be as Crick.

I go with E as well. The premise doesn't specify anything about prior to 1990. So C can't be true if that seminar was not part of program in 1989 or earlier.
