For pollinating certain crops such as cranberries, bumblebees are far more efficient than honeybees. This is because a bumblebee tends to visit only a few plant species in a limited area, whereas a honeybee generally flies over a much broader area and visits a wider variety of species.

Summary

Bumblebees pollinate a smaller number of plant species in a more limited area than do honeybees. This makes bumblebees more efficient at pollinating some crops, including cranberries.

Strongly Supported Conclusions

Cranberries are more efficiently pollinated by pollinators who focus on a narrow range of species in a small area.

When a pollinator visits many species of plants, it decreases that pollinator’s efficiency in pollinating cranberries.

A
If a honeybee visits a wider variety of plant species than a bumblebee visits, the honeybee will be less efficient than the bumblebee at pollinating any one of those species.

Unsupported. This is too broad a claim. The stimulus doesn’t suggest that visiting a small number of plant species makes bumblebees more efficient at pollinating any species—it only makes them more efficient for “certain crops such as cranberries.”

B
The number of plant species other than cranberries that a bee visits affects the efficiency with which the bee pollinates cranberries.

Strongly supported. The difference in efficiency between the two kinds of bee is due to a difference in the geographic range and number of plant species visited by each kind of bee. This suggests that the number of additional plant species visited may affect efficiency.

C
The broader an area a bee flies over, the smaller the number of plant species that bee will be able to visit.

Anti-supported. Honeybees fly over a broader area than bumblebees do, and yet honeybees also visit a larger number of plant species.

D
Cranberries are typically found concentrated in limited areas that bumblebees are more likely than honeybees ever to visit.

Unsupported. The stimulus doesn’t suggest any reason why bumblebees would be more likely than honeybees to visit cranberries. If anything, honeybees visit a broader area and encounter more kinds of plants than bumblebees do.

E
The greater the likelihood of a given bee species visiting one or more plants in a given cranberry crop, the more efficient that bee species will be at pollinating that crop.

Unsupported. Bumblebees are more efficient at pollinating cranberries, but there’s nothing to suggest that this is because they’re somehow more likely to visit cranberries. If anything, honeybees visit a broader area and encounter more kinds of plants than bumblebees do.
