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 1994. D. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1991. E.

+1 C

Inside the group of students, there is a subset: the candidates for the MBA in international business. So, A and B are not clear with that. Because we don't know in which year the course of microeconomics began to be taught to all students, we cannot infer anything related to D and E. _________________

The crucial factors here are; 1. Students should join a business program in MBA International Business. 2. Prior to 1991, there is no hint that microeconomics was necessary. Prior to 1995 does not mean, it is after 1991.

A. The student entered the Business program prior to 1995…. It could be even before 1991, in which case, he need not have taken even microeconomics. Wrong B. The student entered the Business program after 1990 and prior to 1995. …. It is just not Business Program; it should be Business Program of MBA in International Business. Wrong C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1994…. Prior to 1994 does not imply, the joining was after 1991. So C is gone D. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1991….. Prior to 1991, there was no need for microeconomics seminar 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. --- Precisely fixes the joining between the two ends; correct choice.

Here goes the explanation:

After 1990 means 1991 onwards and after 1994 means 1995 onwards

1990 ---1991 ME 1994---- 1995 AE

(ME - Microeconomics , AE Applied Eco) Student took a seminar on ME , so he was there in 1991 but cant be sure about other years , only choice C fits in . Try to fit in the diagram . I got this question wrong first time but was hell bent to solve it next time without looking at explanation _________________

Some of the posts above seem not to capture the logic of the question. The only relevant fact is this: if someone joined the International Business program after 1994, they took Applied Economics. So (taking the contrapositive) if someone didn't take Applied Economics, they didn't join the International Business program after 1994. So the answer is C (though C needs to say 'prior to 1995', and not 'prior to 1994' to be perfectly correct).

All of the detail about Microeconomics is simply irrelevant. It is certainly possible that some International Business students took Microeconomics prior to 1990, which is why E is wrong. _________________

But the question asks:

Quote:

Can we see miss the reference to Microeconomics in the question? On the contrary, the question is not mentioning anything Applied Economics. I think AE is not part of the concern of the question, while ME is very much

Let us look t the temporal order.

Before 1991: neither ME nor AE 1991 to 1194: only ME 1995 onwards: Only AE

Now where can you fix a person with ME? You can’t anywhere other than between 1990 and 1995. That is the reason E prevails.

C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1994. This simply means that if a student took MBA in International business, he should have entered before 1994. Does that imply that the University stopped its program of MBA in International Business after 1994?

C has too many logical holes, while E can be sustaned. _________________

No, the answer is not E, and the information about Microeconomics is indeed irrelevant. There is nothing at all stated in the question about what courses people took prior to 1991. Maybe they took Microeconomics, maybe they took Applied Ecomonics, maybe they took both or maybe they took neither. You seem to be assuming they took neither - that information is not found anywhere in the question. _________________

I chose 'E'.Can someone just help clarify. I somehow feel 'c' is not the correct answer. The lack of consensus between the verbal expert and the gmat tutor has added to my confusion. Someone please help with this!

Re: In the Business program at a university, all candidates for [#permalink]

I think E is the correct option.

In option C, it's mentioned the student entered the university prior to 1994. Case 1 - Say student entered in the year 1992, it satisfies the argument. Hence true. Case 2 - Say student entered in the year 1988. The argument gets false.

Please explain why it is C.

Responding to a pm:

What we know from the argument: - All candidates who entered the program after 1990 took a seminar on Microeconomics (we don't know anything about candidates who entered in 1990 or before. Just that those that entered after 1990 definitely took Microeconomics. So if someone entered after 1990, we can say that he took a seminar on Microeconomics. But if we know that someone took a seminar on Microeconomics, can we say that he entered after 1990? No. Someone could have taken this seminar in 1990 or before too.)

- All candidates who entered the program after 1994 took a seminar on Applied Economics (same logic as above)

A student took Microeconomics seminar but not Applied Economics.

C. If the student was a candidate for the MBA in International Business, then the student entered the program prior to 1994. Had he entered in 1994 or after, he would have taken the Applied Economics seminar. He did not take it means he entered prior to 1995. The option needs to say 1995, not 1994. So I don't like this as the answer.

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. Can we say that he entered after 1990? Not necessary, right? As we discussed above, if someone took the Microeconomics seminar, it doesn't mean he entered after 1990. He could have entered at any time. This is not correct for sure.

So, if I had this question in the exam as is (which I don't like), I would have gone for (A). Note that the question says "If a student in the Business program described above" - I would take it to mean "MBA in International Business". Option (A) correctly uses prior to 1995 and I would hence take it to be true. _________________

Thanks for explanation, Karishma. So, here are we assuming unstated assumption that there was Seminar on Microeconomics even before 1990 and seminar on Applied Economics before 1994 ? As this is not stated in whole stimulus anywhere..this is really a confusing one

Again, thanks for your help !

No. Look, here is the important point - We don't know. We cannot infer anything about Microeconomics and that is why it cannot be a part of our conclusion.

Take another example: If you go to Danny's place after 5:00 pm, you will find him dancing.

This tells us that after 5, you will definitely find him dancing. Does it mean that you CANNOT find him dancing at 4:00 pm? No, it doesn't. We don't know anything about 4:00 pm. He may or may not be dancing at that time. So say you went to Danny's place and saw him dancing. Can you say that you went after 5:00 pm? Not necessary, right? We don't know at what all times he dances. All we know is that he certainly dances after 5:00 so if you go to his place after 5:00, you will see him dancing. He could be dancing at other times also, we don't know.

The argument is exactly the same here: After 1990, everyone must have taken the Microeconomics seminar. But do we know whether they took it in or before 1990 too? No, we don't know. So can we say whether he entered after 1990 or before? No, we don't know. Hence, your conclusion should not have the 1990 part and hence (E) is wrong. _________________

Answer should be C. Key to the answer holds in reading the question with all conditions applied on students. Statements are said about those students who entered in Business program for " International Business". So, the answer is C. _________________
