Question

Simplify the underlined part of the given sentence (if necessary):
Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

• A. pollinating banana, breadfruit, and mango trees; and indirectly help produce
• B. pollinating banana, breadfruit, and mango trees; and indirectly helping to produce
• C. pollinating banana, breadfruit, and mango trees; and they indirectly help to produce
• D. they pollinate banana, breadfruit, and mango trees; and indirectly help producing
• E. they pollinate banana, breadfruit, and mango trees; indirectly helping the producing of

Answer 1

The correct option is B pollinating banana, breadfruit, and mango trees; and indirectly helping to produce

This sentence is again based on parallel structure. There are three actions that we know that the bats are doing - 'aiding' in the dispersal of cashew and other nuts, pollinating bananas and indirectly helping in creating tequila by pollinating the agave plants. These three actions need to be in parallel. Since 'aiding' already exist in the question, the rest of the actions need to follow this structure (-ing form). On the basis of this we can eliminate all other options but B. So, B is the correct answer.
