Sentence Correction

The health benefits of tea have been the subject of much research; in addition to its possibilities for preventing and inhibiting some forms of cancer, the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke.
A. in addition to its possibilities for preventing and inhibiting
B. in addition to its possibilities to prevent or inhibit
C. besides the possibility that it prevents and inhibits
D. besides the possible preventing and inhibiting of
E. besides possibly preventing or inhibiting

First, it's a good idea to identify the subject of the sentence containing the underlined words: the brewed leaves of C. (plural) . After a semicolon, you always find a complete sentence, unless it is used in a complex list

Thus A, B and C can be quickly ruled out.

Looking at D and E, the former contains an unidiomatic expression: the possible preventing.

Choose E

A, B and C are also complete sentence.

Kevin,

When you say that "After a semicolon, you always find a complete sentence", do you mean that we can't have pronouns referring to subjects in the phrase before the semi-colon?

Also, can you give examples of "complex lists"?
