Argument: "A recent study showed that children who regularly eat breakfast perform better in school than those who frequently skip it. Therefore, schools should implement mandatory breakfast programs to significantly improve students' academic performance." Which of the following, if true, most weakens the argument?

A Many children who eat breakfast consume unhealthy sugary cereals.
B The study did not control for socioeconomic factors, where wealthier families might provide breakfast more consistently and also have more resources for academic support.
C Some students skip breakfast because they are not hungry in the morning.
D A balanced diet, not just breakfast, is essential for overall child development.

✓ Correct Answer: Option B

The argument assumes a causal link between breakfast and performance. Option B suggests a confounding variable (socioeconomic status) that could be the true cause of both consistent breakfast eating and better performance, weakening the school's proposed solution.
