Question

which set of central ideas can be found in both articles?
to perform well, the human body needs a variety of nutrients.
and
the types of nutrients the human body needs have changed over time.
the nutritional needs of an omnivore are different from those of a vegan.
and
a variety of plant - based foods can offer adequate nutrition.
seeking out nutritious food options can be stressful. and
the digestive system functions more effectively when the majority of the foods consumed come from plants.
a balanced diet should be based on a healthy lifestyle.
and
people should opt for a diet that can give them the best nutrition possible.

Explanation:

• Option a: The second part “The types of nutrients the human body needs have changed over time” is not likely to be a common central idea in both articles as there is no indication of time - related change in the given text snippets.
• Option b: The first part “The nutritional needs of an omnivore are different from those of a vegan” is about a contrast between two types of eaters. The second part “A variety of plant - based foods can offer adequate nutrition” is about plant - based nutrition. These two ideas do not seem to be connected in a way that would be common central ideas for both articles.
• Option c: The first part “Seeking out nutritious food options can be stressful” has no basis in the given text snippets. The second part “The digestive system functions more effectively when the majority of the foods consumed come from plants” also has no support.
• Option d: “A balanced diet should be based on a healthy lifestyle” and “People should opt for a diet that can give them the best nutrition possible” are general statements about diet and nutrition that can be inferred from the text snippets. The left - hand snippet talks about getting nutrients (implies best nutrition) and the right - hand snippet mentions a healthy lifestyle (from “a healthy lifestyle” in the text).

Answer:

D. A balanced diet should be based on a healthy lifestyle. AND People should opt for a diet that can give them the best nutrition possible.
