hi there,
is there any OE for this question?
Is it really an official GMAT question? if yes, what year?
I know E is correct, but why C is not? dont tell me that otherwise the number of food poisoning for restaurants would be great too.
cuz what if the food restaurants serve for their indoor customers and the food they serve in banquets differ in their quality?
then the food poisoning cases are in direct relation with the restaurants, while caterings may be considered responsible for them (since it happened in a banquet).
how can we be sure that C is incorrect plz????

Hi Omraan.

Your thinking is right. But that's why C is wrong.

Basic knowledge of Resolve the Paradox question in GMAT

Just a small remind about resolve the paradox question in GMAT. According to "Power Score CR Bible - Resolve the Paradox question", to solve this kind of question, you must select the answer choice that contains a possible cause of the situation. So, when examining answers, ask you self if the answer choice could lead to the situation in the stimulus. If so, the answer is correct. If the answer is HALF RIGHT, HALF WRONG, the answer is INCORRECT.

Let examine C:

Before examine C, I just want to repeat "your thinking is right". C does not assume the qualities of catering services and of restaurants are the same (that's the case everybody assumes and concludes C is wrong, but that's only half of the answer). Definitely, there's a possibility that qualities of two services are different.

If qualities are the same. What happens? if the number of food poisoning of catering services is high, that of restaurants would be high too --> The paradox couldn't be solved.
If qualities are different. if the number of food poisoning of catering services is high, that of restaurants maybe not high --> The paradox could be solved

That's why C is half right, half wrong. Hence, it's clearly not the answer.

Takeaway:

1. The right answer in Resolve the Paradox question could lead to the situation in the stimulus.
2. The answer that is half right, half wrong, is always wrong.


I hope my post helps you.
