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.



Nothing is mentioned of that possibility, nor can we assume by the argument that some international business students might have taken microeconomics prior to 1990. Why can't it be equally assumed that some student might have taken AE before 1990. I think E is far better. On top of that , C should not have sad prior to 1994.



I think you need to go through the entire thread. I have explained in detail why (E) is incorrect. This is a very conceptual issue so try to ensure that you understand it well.

All 1990 candidates--> took MicroEconomics Seminar
Negate: Not Microeconomics seminar-->not 1990 candidate
Similarly
All 1994 candidates-->took AE Seminar
Negate: Not AE Seminar--> Not 1994 Candidate

C: Correct. Because If candidate took Micro and( NOT AE --> Not 1994 candidate)
Hence, C is correct.

C.

Let's assume that a student admitted in MBA 1-yr program in 1989. He will complete the course in 1990 and will take microeconomics. students admitted in 1990 will complete it in 1991 will take the same. students entered in 1991 will graduate in 1992 and will take the same. Students in 1992 & 1993 will do the same.
Students entered in 1994 will graduate in 1995 and will take the applied economics.

Let's evaluate the answer choices:

I go with E, as option C says prior to 1994(highlighted in red), it can be in 1980, but the premise says after 1990. option E completely justifies the premise.

What if the student entered in 1985. There is no sufficient information given in C. So it should be E

Enjoyed solving this one , so posting my explanation -

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

Prior to 1995 can include period prior to 1991 as well , further the option talks about student who entered Business program ( our scope is candidate for the MBA in International Business ), hence totally incorrect....

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

I would have selected this option had the question stem mentioned about candidates for the MBA in International Business , here we are talking in general ( about student of Business Programme ) , so this is out of scope ....

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 can mean 1989 as well , hence incorrect...


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 micro economics was not there, hence incorrect.

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.

That's it , this is perfect...

Hence Correct answer will be (E)

:-D

The answer is E
This question is not as tough as many people have made it here.

Here's the logic. Microeconomics and Applied economics were taught at different years in the university.
Ok ask yourself, is there a possibility that before 1990 all student attended some other seminar such as Economic Theory, Econometrics, International trade etc etc.. There may or may not be a possibility , but we have to be careful and follow the stimulus closely by limiting and using only that informations that matches with given years. This gives us three categories

A) TILL 1990 :- we don't know .. no info is given:- WE DONT KNOW
B) FROM 1991 to 1994 all student attended MicroEconomics:- 1991,1992,1993,1994, MICROECONOMICS
C) From 1995 onwards all student attended Applied Economics:- 1995,1996,1997,1998,1998,1999,2000.... APPLIED ECONOMICS

If you want to visualise in a linear fashion
(Before 1990 NO INFO) (1991MICROECONOMICS) (1992 MICROECONOMICS) (1993MICROECONOMICS) (1994 MICROECONOMICS) (1995 APPLIED ECONOMICS)--->

Now the question being asked to us is :-
If a student in the Business program described above took a seminar on Microeconomics but did not take a seminar on Applied Economics what must be true.
Match it with the info chart.

He must fall in the category B) AFTER 1990 but BEFORE 1995 (--1991,1992,1993,1994---)

This matches with option E.
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.


Done :-D


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, and all candidates for the MBA in International Business who entered the program after 1994 took a seminar on Applied Economics.

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 1994.
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.

Please explain why it is C.

This question is same to the following:

Moreover, the answers of the above two questions are highly controversial. Experts are divided in their reasoning.

Explain plz...


Okay. I would argue against E being the correct answer, and for C being the correct answer.

The argument states that

1. ALL MBA IB students after 1990 took Micro Econ.

2. ALL MBA IB students after 1994 took App Econ.

Does 1 mean that NO MBA IB STUDENT TOOK MICRO ECON BEFORE 1990?

Certainly not. Yes, we know for certainty that each and every MBA IB student took Micro Econ after 1990, but we cannot conclude the above. This similar reasoning goes for statement 2 also.

And thus, we cannot say for certainty that the student entered between 1990 and 1994, inclusive. But, we can certainly say that the student entered before 1994 because he/she did not take App Econ, because we know that each and every MBA IB took App Econ.

What's the source?

Expert comments welcomed.

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.

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.


I agree with karishma, even i had answer (A) in my mind before scrolling down to other explanation.

I think one main point to note -> it is mentioned that all who joined after 1991 took ME course, but this does not mean ME course was offered only after 1991, may be it was offered before 1991 but not mandatory. May be the student in the question had joined before 1991 and took ME course. So all choice with 1991 - 1995 need not be true.
