Summary
Among adults in country X, most consume an increasing amount of fat as they get older. For example, at 30, they eat less fat than at 40, and at 40, they east less fat then at 50. But for almost all adults in country X, the percentage of fat in a person’s diet stays the same throughout adulthood.
Strongly Supported Conclusions
If the amount of fat increases with age, but the percentage of one’s diet that is fat stays the same, that implies the overall amount of food eaten must increase with age. For example, let’s say fat is 10% of one’s diet. If you eat 200 grams of fat at 30 years old, that means you’re eating 2000 grams overall. Let’s say at 40 years old you eat 300 grams of fat; that means you’re eating 3000 grams overall.
A
They generally consume more fat than do people of the same age in other countries.
Unsupported. We don’t know anything about other countries besides country X.
B
They generally eat more when they are older than they did earlier in their adulthood.
Strongly supported. If the amount of fat eaten increases with age, but the proportion of fat in one’s diet stays the same, that means the overall amount eaten must increase.
C
They generally have diets that contain a lower percentage of fat than do the diets of children in country X.
Unsupported. We don’t know anything about children in country X.
D
They tend to eat more varied kinds of food as they become older.
Unsupported. Although the stimulus implies that the adults eat more food as they get older, that doesn’t mean they’re eating different kinds of food. They might just eat the same foods, but more of it.
E
They tend to lose weight as they become older.
Unsupported. We can infer that adults in the country eat more as they get older, but that doesn’t imply they lose weight as they get older. If anything, that could suggest they gain weight as they get older.
