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?

A. The student entered the Business program prior to 1995.

B. The student entered the Business program after 1990 and prior to 1995.

C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1995.

D.If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1991.

E. If the student was a candidate for the MBA in International Business, then the student entered the program after 1990 and prior to 1995.

Who is a candidate for MBA in IB? A student who has been admitted and fulfilled the course requirements, not all those who applied.

Stem is talking about candidates for MBA in IB not about MBA in Finance or marketing.

B has broader scope. In other words we only know about candidates for MBA in IB. It is very well possible that a marketing MBA candidate who might have entered the program after 1990 or before 1995 might fit this or might not fit this. We cannot apply it to the entire business program.

Hence E.

But..."If a student in the Business program described above took a seminar on Microeconomics but did not take a seminar on Applied Economics" limits the scope to only those students.

Another E. The question describes the student of the business program and not the IB.

premise one: all candidates who entered the program after 1990 took a seminar on M, and all candidates who entered the program after 1994 took a seminar on AE
premise two: the student who took a seminar on M but didn't take seminar on AE

so we can infer that the student is belong to the candidates who took a seminar on M, and that the period of the program is less than 4 years
imo, only D, the best ans

E

A and B are attractive BUT the premise doesn't say that ONLY the students of IB will be attending Microeconomics.

because the period of program is less than 4 years, and because student took a seminar on Microeconomics but did not take a seminar on Applied Economics,
so if B is true, the student should take seminar on Applied Economics, but Microeconomics.

folks sorry to add on to the already stated answers. But wanted to bring in a different perspective..hope you wont mind. see inline diag below
Attachment:

diag B.JPG [ 24.83 KiB | Viewed 2005 times ]

Question stem states that a student took MicroEconomics(ME) but not Applied Economics(AE). So the student could be in either Row 1(Intl Business) or Row2(Some other discipline). Now for the choices

A is incorrect, coz there is a possibility that a student from Row2 took ME in 96.

B is incorrect coz of the same reason. There could be a Row2 guy in 96 who took ME

C, D and E narrow the focus to Row1, by saying Intl Business..so that good. We are looking for an answer that clearly restricts us to Row1 and between 91 and 94

While C sounds good, it doesn't clearly deal with students enrolled prior to 90. So incorrect

D goes way beyond scope and talks about prior to 91, so incorrect

E clearly narrows it down to Row1 between 91 and 94. So that's my pick for answer.

~ rest of the folks, me eager to hear OA

E. If the student was a candidate for the MBA in International Business, then the student entered the program after 1990 and prior to 1995.

B. We need to be focused on "Microeconomics" and 1990-1995.

A. Out of scope:- Prior to 1995 could mean prior to 1990 and we do not know about the seminars offered before 1990.
B. Perfect.
C. Out of scope:- Pretty much similar to A.
E. Out of scope:- Similar to D.

Agree with E. I do not know why I choose B instead of E.

May be because of lots of pressure. Sorry guys.

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? ( Microeconomics + Not Applied Economics) --> ???

Candidate who entered the program in 1990 + (1991 through 1994) --> Microeconomics
Candidate who entered the program in 1994 + (1995 to the present) --> Applied Economics

If Mircoeconomics we cannot infer that it was 1991 through 1994 because this is a sufficient condition.
Not Applied Economics --> not after 1994 (1994 and before)

A. The student entered the Business program prior to 1995.
This statement could be true. However, we must eliminate this choice because we cannot ensure that a candidate for the MBA in 1975 took Microeconomics.
B. The student entered the Business program after 1990 and prior to 1995.
My choice. This follows directly from the statements above.
C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1995.
This is wrong for two reasons. This means that all candidates entered the program. Too strong! Additionally, we must eliminate this choice because we cannot ensure that a candidate for the MBA in 1975 took Microeconomics.
D.If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1991.
Eliminate. This means all students who applied attended the school. This is too strong.
E. If the student was a candidate for the MBA in International Business, then the student entered the program after 1990 and prior to 1995.
Eliminate. This means all students who applied attended the school. This is too strong.

I give! I agree with you guys and E. Is there such a thing as a negative Kudo? Give me one of those....

KUDOS
It's C. I think a lot of you guys are getting the logic backwards.

D.If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1991.

E. If the student was a candidate for the MBA in International Business, then the student entered the program after 1990 and prior to 1995.

A was my first choice until I got to C and realized that they wanted you to focus specifically on the International Business MBA.

B & E are not correct and here's why...We know for a FACT that this guy has taken the microeconomics seminar. The problem is, we don't know whether he was required to take it, or whether he just took it for the hell of it. The microecon seminar only became a required course after 1990. This guy could have entered the IB program in '89, taken the microecon seminar because he thought it was interesting, and then went on his merry way to getting his degree. You guys are right that if he entered the program between 91-94 he would HAVE to take the microecon course. But that's getting the logic backwards. We already know he took the microecon course. We just don't know whether it was a requirement or not.

C is the correct answer. If the guy hasn't taken the Applied Econ seminar, then there is no possible way that he entered the course later than 1994. If he entered after 1994, he would have been required to take that class. That's ALL we know in this problem. Just because he took the microecon course doesn't mean he did it because of a requirement.

D is wrong because, as many of you have pointed out, he could have entered the program between 91 & 94, in which case he would have taken Microecon but not Applied Econ.

In summary, I think a lot of you are getting the logic wrong for this problem. You have to start with what you know about the student: he took Micro but not Applied. Then you realize that there was a requirement for Applied, so the fact that he didn't take it means that he was not required to. That would get you to the right answer. Further, you could realize that just because he took micro does not mean he was required to take it. Basically, a requirement guarantees that you take the class...so lack of class means lack of requirement. Presence of class does not necessarily mean presence of requirement.

Hope that helps (and hope it was right, too). Good luck w/ the studying, everybody. Peace.

EDIT:

Just a little diagram:

Requirement ----> Class
Class ----/-----> Requirement
BUT
No Class -------> No requirement

Is that the contrapositive? I forget those terms...maybe somebody who remembers can enlighten us?

Why not C?

Premises:
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...but it does not say all Micoeconomics taker must be student entered the program after 1990

That student...
took a seminar on Microeconomics
-->the student may take micoeconomic due to the complusory requirement or take it as an elective
but, did not take a seminar on Applied Economics--> must be prior 1995

C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1995.

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
