Question

read the rough - draft paragraph.
since popcorn is a whole grain, it is high in dietary fiber,
which helps in the regulation and maintenance of the
digestive system. to maximize the healthful benefits of
eating popcorn, be sure to only munch on either air -
popped popcorn or kernels that have been popped using
little oil. in addition to providing dietary fiber, popcorn is
also a source of antioxidants. this means that like fruits
and vegetables, popcorn contains compounds that can
reduce or prevent certain cancers. so, not only is
popcorn a tasty treat, it is also a nutritional powerhouse.
which topic sentence should be added to this body
paragraph?
foods loaded with fiber have been known to lower the
risk of heart disease.
recent studies prove that popcorn is one of the
the healthiest snack choices.
antioxidants are sought after by many health -
conscious people.
air - popping and microwaving are two methods of
preparing popcorn.

Explanation:

The paragraph discusses the health benefits of popcorn (high in dietary fiber, antioxidants, etc.) and how to prepare it healthily. The topic sentence should introduce the main idea of popcorn being a healthy snack.

• The first option focuses on fiber - related heart disease risk reduction, which is too narrow as the paragraph has more about popcorn's benefits.
• The second option "Recent studies prove that popcorn is one of the healthiest snack choices" encompasses the overall content of the paragraph (fiber, antioxidants, healthy preparation) as it makes a general claim about popcorn's health - promoting nature.
• The third option is about antioxidants in general, not specifically related to popcorn as the main subject.
• The fourth option is only about popcorn preparation methods, which is just a part of the paragraph's content.

Answer:

Recent studies prove that popcorn is one of the healthiest snack choices.
