Though ice cream is an excellent source of calcium, dairy farmers report that during the past ten years there has been a sharp decline in ice cream sales. And during the same period, sales of cheddar cheese have nearly doubled. Therefore, more and more people must be choosing to increase their intake of calcium by eating cheddar cheese rather than ice cream.
The reasoning above is most vulnerable to criticism on the grounds that it
(A) fails to produce statistical evidence supporting the dairy farmers’ claims
(B) fails to consider alternative explanations of the decline in sales of ice cream
(C) relies solely on the testimony of individuals who are likely to be biased
(D) presumes, without providing justification, that ice cream is a better source of calcium than is cheddar cheese
(E) presumes, without providing justification, that people who eat cheddar cheese never eat ice cream
EXPLANATION FROM Fox LSAT
What the **** is this? Patently ridiculous. People do
not choose to eat either ice cream or cheddar cheese because of the goddamn calcium content. People eat ice cream and cheese because of the taste, and that’s pretty much it!
A) This would almost never be the answer. You’re not required to provide “statistical evidence” that backs up your premises. If you were, then every argument would be encyclopedic in length.
B) If by “alternative explanations” this answer might mean “taste,” then this could be a good answer. Maybe people decided they like the taste of cheese more than they like the taste of ice cream, so they’re eating cheese over ice cream and it has nothing to do with calcium. That’s my case for this answer.
C) The argument doesn’t do this. We’re not given any reason why the dairy farmers would lie about increases and decreases in the sales of their dairy products.
D) It doesn’t do this either. The argument says that ice cream is an excellent source of calcium, and it assumes that cheddar cheese also has calcium in it. The argument never presumes that cheddar cheese is a better source of calcium.
E) It certainly never says this, or assumes it.
The only plausible answer is B. If we read “alternative explanations” to mean the obvious taste explanation, it’s a terrific answer.
