Question

Read the passage and answer the question that follows.

People from Asia tend to live on a vegetable and fruit diet while eating meats low in fat such as fish. They eat very little bread-wrapped foods such as sandwiches, hamburgers, bagels, paninis, etc. Few of them suffer from obesity, and obesity for them does not increase with age. However, some immigrant families who do move to America and adopt American bread-based foods, like morning bagels and lunchtime sandwiches, do start showing signs of obesity - more weight, higher blood pressure, and higher cholesterol. Though suggestive, these facts do not establish bagels and sandwiches as the culprit in obesity, however, because ___.

Which of the following most logically completes the argument?

• A. genetic factors could account for the lack of increase in weight with age among such people
• B. people eating bagels and sandwiches and living from birth in more urban societies generally have a tendency to have more weight and higher blood pressure
• C. it is possible to have a low bagel-sandwich diet upon moving to America
• D. there are changes in other aspects of diet when immigrants move to America
• E. carbohydrates (the foundation for bagels and sandwiches) are a necessity for human life, and death can occur when the body is deficient in carbohydrates

Answer 1

The correct option is D there are changes in other aspects of diet when immigrants move to America

In this kind of question (always tough) generally if you see at the end words such as since because, then we have or an assumption or a strengthen question

Between options A and D: A talks about genetic factors but if you look closer at the conclusion is stated
However, some immigrant families who do move to America and adopt American bread-based foods
D makes more sense and hence the answer.
