"Surprising" Phenomenon
Nuts are high in calories, which increases the chance of becoming overweight—yet people who eat nuts are less likely to be overweight than people who never eat nuts.
Objective
The correct answer will be a hypothesis that explains how people consuming a certain high-calorie food can gain less weight than those not consuming that high-calorie food. The explanation could be because nut-eaters mitigate their caloric intake with exercise, or because people who never eat nuts eat a higher-calorie diet overall.

The likelihood of ████████ ██████████ ███████ ███ ████ ██ ███ ████ ████████ ███ ████████ ███ ████ ██ ███ ███████ ███ █████ █████ ████████ ███████ ████████ █████████
This seems like a component of the explanation we’re looking for. However, we need to know that the nut-eaters are actually getting more physical activity. Without that element, this doesn't help.
b
Due to the ████ ████ ████ ███ ████ ██ █████████ █████████ █ ████████████ █████ ████████ ████████ █ ███████ ██ ██████████
This is missing a comparative aspect. How do we know that people who never eat nuts aren’t reaching the same feeling of satiation with foods? Without the comparison, this isn't useful.

If people who █████ █ ███████ ████ ██ ████ ███ ████ ██████ ██ ██ ██████████ ████ ██████ ███ ███████ ████ ████ ██████████ ████ ████ ████ ██████ ███ ██ ███████ ███ ██████ ████ █████████
It doesn’t matter whether a food should or shouldn’t be avoided. We need to know why eating high-calorie nuts seems to in fact prevent weight gain, and this doesn't tell us that.
d
On average, people ███ █████ ███ ████ ███████ ███ ████ █████ ████████ ███ ███ ██ ██████ ███ █████████ ███ █████
If both groups are eating the same amount of calories, then why are the nut-eaters less likely to be overweight? We need more information on how the two groups differ, rather than how they’re similar.
e
Most people who █████████ ███ ████ ███ ███████████████ ████ ██ █████ █████ ██████ ██████ ████ ██ █████ ██████████ █ ██████ █████████
People who eat nuts are more satisfied after eating. People who don’t eat nuts eat foods that make them feel hungry, which leads to overeating. This explains why eating nuts prevents weight gain.
