Change the degree of comparison of the following sentence.

The fruit fly is often used to study genetic mechanisms, because it reproduces rapidly scientists can observe the effects of experiments on several generations.

• A. Mechanisms, because it reproduces rapidly
• B. Mechanisms, since it reproduces rapidly,
• C. Mechanisms, since, with its rapid reproduction,
• D. Mechanisms; because it reproduces rapidly,
• E. Mechanisms; then rapid reproduction allows

Answer 1

The correct option is D Mechanisms; because it reproduces rapidly,

The underlined part of the sentence has a punctuation error. It should be replaced with option D as semicolon should be used to join two complete thoughts (The fruit fly.... mechanisms and Because.... generations).

Rest of the options do not use correct punctuation and verb forms.

Thus, option D is the correct answer.
