One should always capitalize the main words and the first and last words of a title. But one should never capitalize articles, or prepositions and conjunctions with fewer than in the middle of a title.
What this question is testing
The Rules
Two rules in the stimulus. Rule 1 says some words always get capitalized (main words, first/last words). Rule 2 says some words never get capitalized in the middle of a title — articles, and prepositions or conjunctions with fewer than five letters.
Evaluate
The trick on Must-Be-True questions is to combine the rules to draw a tight inference. If a middle-of-title word should be capitalized, then it cannot be in the never-capitalize category. That is, it cannot be an article, and it cannot be a short conjunction or preposition.
Goal
Find the answer that exactly captures this contrapositive. Watch for answers that switch directions, overstate, or stray from the rules.
