Logic Breakdown
Passage Summary: Everyone who joined the contest got a T-shirt; Juan has the T-shirt, so the author assumes Juan joined the contest.
Conclusion: Juan must have entered the software company's logo contest.
Reasoning: The contest rules stated that everyone who entered would receive a T-shirt with the new logo, and Juan possesses such a T-shirt.
Analysis: This argument is a classic case of 'confusing a sufficient condition with a necessary one.' The rule says: If you enter, then you get a shirt. It does *not* say: If you have a shirt, then you must have entered. Juan could have bought the shirt, found it, or received it as a gift from an actual entrant. The flaw is assuming that the contest was the *only* way to obtain that shirt. Look for an answer that identifies this 'mistaken reversal' of the logic.

Correct Answer
B
The argument takes a sufficient condition (entering) as necessary for the outcome (having the T-shirt). This is the classic mistaken reversal/affirming the consequent.
