Question

Which of the following is the basis for one concern regarding the broad planting of BT-toxic crops?

exposure to BT may turn insects into super insects, resulting in things like BT-toxic bee stings

BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops

pollinating species will come to prefer BT-modified crops, and will leave non-GMO crops unfertilized

species of beneficial pollinators will develop a natural immunity to the BT toxins

Answer 1

BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops

Step-by-step explanation:

The correct answer is BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops. People would prefer that beneficial pollinator species become BT-immune. There is little concern about cross-genus exchanges of genetic material leading to BT-toxic bee stings, or that pollinating species will come to prefer BT-modified crops and ignore natural, unmodified crops.
