If the ingredients are not list how would one know if the preferred spice is used?

One doesn't have to know whether the preferred spice was used to answer the question.

Premise 1: Variation ONLY in spices used creates different food preferences
Premise 2: In the future, we will see no variation in spices used (IE only 1 spice will be used)

What is required to make the connection between 1 and 2? That there is only one spice which creates food preference.

OA:
A) While this may be true, the implication of the passage is that spice makes a big difference and would lead to the selection of another dish rather than the same casserole with a different spice. B) While probably true, it is unrelated to the passage, which gives no logical basis for any inference about food value. C) While it may seem unlikely, it is indeed an assumption logically consistent with the passage. If a particular spice was preferred by the majority of the people surveyed, this would explain why the cafeteria would start using a single spice based on the survey results. This is the correct answer. D) This statement is not directly relevant to the passage. E) This is not relevant to the passage, which makes no mention of price, and provides no basis for logical inferences about price.

Choice C is the best. Shava and gmattokyo make the best case for that answer. Besides, the other options were a little strange.

I wish every gmat inference question can be as easy as this one. CHoice C is an obvious one.

Was between A and C, they seem pretty close especially when negating each. But I guess that there are other plates that people can eat, in which case A will not be really a necessary assumption

A survey of food preferences by the school cafeteria showed that casseroles, which were identical in every respect except the spice used, received very different ratings. Therefore, we can expect in the future to find no variation in the spice used. Which assumption is a logical inference from the above passage?
.
A) If the preferred spice is not used, the buyer is usually willing to accept another spice....CAN'T SAY THAT
B) Casseroles differ significantly from each other with respect to food value...CAN'T BE INFERRED
C) There is a single spice generally preferred in the casseroles tested......sounds ok....AS THIS PREFERRED SPICE FLAVOUR COULD BE THE ONLY ONE ON OFFER ...TO INCREASE RATINGS
D) Menu descriptions of this dish should list all the ingredient....CAN'T BE INFERRED
E) Shoppers give more emphasis to flavor than to price in food purchasing....SOUNDS CORRECT ..NOTE the wordings..."identical in every respect except the spice used"

"C" AND " E " SOUND OK.... BUT I PREFER "C".

EVEN "E" APPEARS TO BE A VERBATIM PREMISE..."..which were identical in every respect except the spice used, received very different ratings... WHEN TWO THINGS ARE IDENTICAL....THAT MEANS COST TOO.... BUT NOW THE ONLY DIFFERENCE IS IN FLAVOUR AND THIS SHOULD BE THE BASIS OF CHOICE........
COULD SOMEONE EXPLAIN WHY THIS CANNOT, ON ITS OWN, BE AN INFERENCE ?
