Restaurant manager: In response to requests from our patrons for vegetarian main dishes, we recently introduced three: an eggplant and zucchini casserole with tomatoes, brown rice with mushrooms, and potatoes baked with cheese. The first two are frequently ordered, but no one orders the potato dish, although it costs less than the other two. Clearly, then, our patrons prefer not to eat potatoes.
Which one of the following is an error of reasoning in the restaurant manager’s argument?
(A) concluding that two things that occur at the same time have a common cause
(B) drawing a conclusion that is inconsistent with one premise of the argument
(C) ignoring possible differences between what people say they want and what they actually choose
(D) attempting to prove a claim on the basis of evidence that a number of people hold that claim to be true
(E) treating one of several plausible explanations of a phenomenon as the only possible explanation

Which one of the following is an error of reasoning in the restaurant manager’s argument?
(A) concluding that two things that occur at the same time have a common cause
(B) drawing a conclusion that is inconsistent with one premise of the argument
Conclusion is consistent to the premise - no one orders the potato dish
(C) ignoring possible differences between what people say they want and what they actually choose
(D) attempting to prove a claim on the basis of evidence that a number of people hold that claim to be true
There is only a single claim and it is not explained. rest of the sentences are facts/observation.
(E) treating one of several plausible explanations of a phenomenon as the only possible explanation
People may dislike potato or cheese, its not certain that they do not order the dish just because of the potatoes
Ans: E

Reasoning: As none of Patrons order the potato dish, they do not prefer potatoes.
Pre thinking: Can there be other reasons??
(A) concluding that two things that occur at the same time have a common cause
Irrelevant.
(B) drawing a conclusion that is inconsistent with one premise of the argument
The conclusion is consistent.
(C) ignoring possible differences between what people say they want and what they actually choose
People actually chose ' an eggplant and zucchini casserole with tomatoes, brown rice with mushrooms' . We can not conclude that patrons did not want/want potato.
But, we need a perfect reasoning error and this option may/may not serve our purpose. Let's keep it for time being.
(D) attempting to prove a claim on the basis of evidence that a number of people hold that claim to be true
'Which claim' . Out of scope
(E) treating one of several plausible explanations of a phenomenon as the only possible explanation.
This is better than 'option C' .explains the flaw in a better way.
Our answer is E.
