GWD7-33 我的问题好象没讨论到

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.

1. in addition to its possibilities for preventing and inhibiting

2. in addition to its possibilities to prevent or inhibit

3. besides the possibility that it prevents and inhibits

4. besides the possible preventing and inhibiting of

5. besides possibly preventing or inhibiting

看了前面的讨论，说A,B中its错。知道了in addition to的用法，我知道这里its只能指代the brewed leaves of Camellia sinensis 。我的问题是分号后面的句子中的代词可不可以指代前一句中的词，在这题中就是：如果不考虑in addition to，ITS可不可以指代前句中的TEA？

跟in addition to没有关系。这里的分号割裂的是2句独立的句子，its无法指代另一句句子中的对象。
