Pay close attention to this statement
"the more bitter a food tastes, the less children like it". Apparently, this is the main premise on which the argument depends.
There is a classic solution for GMAT assumption questions.
If A caused B, only and only A caused B; C/D/E did not cause B.
Basically, only A is sufficient to cause B and A causing B is not affected by any other factor.
Coming back to our question, the author has made an implicit assumption
'How strongly children 'Dislike' some food depends on how bitter it is'Please note, how strongly children 'like' food is totally irrelevant.
Lets find the answer by process of elimination :
(A) Supertasters like mild cheddar cheese more than do regular tasters. -
INCORRECT. How strongly children like something is irrelevant.(B) The age of the child is the most important factor in determining whether that child is a nontaster, a regular taster, or a supertaster. -
INCORRECT. Age is irrelevant for this argument.(C) The sweeter a food tastes, the more children like it.
INCORRECT. Again, how strongly children like something has no relevance.(D) Bitterness is the only factor relevant to how strongly children prefer sharp cheddar cheese to mild cheddar cheese. -
CORRECT. (E) Nontasters tend to like a wider variety of foods than do regular tasters, who in tum like a wider variety of foods than do supertasters. -
INCORRECT. Wide variety of food is not relevant; Argument is about cheddar.
Say Cheeeeeese!!
