Passage Summary: Researchers gave one group extra calories via alcohol and gave another group alcohol instead of some of their usual food. Even though the first group ate more total calories, both groups gained the exact same amount of fat.

Reasoning: One group added alcohol to their diet (increasing total calories), while another group replaced some food with alcohol (keeping total calories the same); both groups ended up with the same amount of new body fat.

Analysis: This is a Most Strongly Supported scenario, so we need to find a deduction based strictly on these results. The surprising part is that the group with the higher total caloric intake didn't gain more fat than the group whose total calories stayed the same. This implies that the extra calories from the alcohol in the first group didn't contribute to fat gain in the way we would expect, or that alcohol's effect on fat gain is somewhat independent of the other calories consumed. Look for an answer that addresses this discrepancy in how calories from alcohol are processed.
