Logic Breakdown
Passage Summary: Hana said she wasn't inviting her brothers, but she ended up with a gift they intended to buy her, so the author assumes they showed up after all.
Conclusion: At least some of Hana's brothers must have attended her birthday party despite her earlier claims.
Reasoning: Hana received a specific recording at her party that her brothers had planned to give her.
Analysis: The author is making a massive leap by assuming that the brothers are the only possible source of that recording. Perhaps Hana's brothers have excellent taste and a friend of hers simply bought the same popular album, or maybe the brothers mailed the gift because they were, in fact, not invited. To find the flaw, look for an answer choice that points out the author fails to consider alternative ways that recording could have ended up at the party. It's a classic case of assuming a single cause for an event when other explanations are perfectly plausible.

Correct Answer
D
D correctly describes the error: the argument fails to show that a fact true of some people (the brothers planned to give the recording) is true only of those people, so it wrongly infers the brothers’ presence from the mere presence of the recording.
