Question

look at these details from a paragraph about the same topic:

• bees pick up pollen when they visit flowers, looking for nectar.
• bees transfer some of the pollen they pick up to other flowers that need it.
• bees carry some of the pollen they collect back to their hive to feed other bees.

choose the main, or central, idea that ties all the details together.
bees take pollen from some flowers and give it to others.
bees can carry pollen to places over two miles away.
flowers produce nectar to attract insects like bees.
bees play an important role in transferring pollen.

Explanation:

The details mention bees picking up pollen, transferring it to other flowers, and carrying it back to the hive. The first option only focuses on transfer between flowers. The second option talks about distance (not in details). The third option is about flowers (not bees' role). The fourth option encompasses all - bees' role in pollen transfer (picking up, transferring, carrying back).

Answer:

Bees play an important role in transferring pollen.
