Logic Breakdown
Passage Summary: A person eating four doughnuts gets about 680 calories, while a person eating one bagel gets 500 calories unless they add cream cheese or butter, so the two meals are basically the same.
Conclusion: There is very little difference in total calorie intake between a typical doughnut eater and a typical bagel eater per sitting.
Reasoning: A typical sitting of four doughnuts contains 680 calories, while a single bagel contains 500 calories but can reach the 680-calorie range if spreads are added.
Analysis: The author is trying to equate 680 calories with 500 calories by relying on the 'spreads' exception. For the conclusion to hold that they are 'very similar,' the author must assume that typical bagel eaters actually do use enough spreads to close that 180-calorie gap. If the typical bagel eater consumes it plain or with light spreads, the 180-calorie difference—which is nearly a 30% increase—would likely be considered significant. Look for an answer that confirms bagel eaters typically add those high-calorie spreads.

Correct Answer
D
The conclusion relies on the doughnut eater’s total staying at 680. If typical doughnut eaters add extra calories, the gap with a typical bagel eater could be large, undercutting the “very little difference” claim. Negation test: if typical doughnut eaters do add caloric substances, then their totals exceed 680, and the conclusion that the totals differ very little can fail.
