Question

In line 71427, the authors state that a certain hypothesis can best be tested by a trial. Based on the passage, which of the following is a hypothesis the authors suggest be tested in a trial?

• A. Honeybees that are exposed to both pyrethrums and mites are likely to develop a secondary infection by a virus, a bacterium, or a fungus.
• B. Beekeepers who feed their honeybee colonies a diet of a single crop need to increase the use of insecticides to prevent mite infestations.
• C. A honeybee diet that includes pyrethrums results in honeybee colonies that are more resistant to mite infestations.
• D. Humans are more susceptible to varroa mites as a result of consuming nutritionally deficient food crops.

Answer 1

Answer: (C)

A honeybee diet that includes pyrethrums results in honeybee colonies that are more resistant to mite infestations.

In the second and third sentences from the third para, the speakers suggest that the problem could be a diet deficient in pyrethrums that fight mite infestations. Without feeding on plants with pyrethrum, the bees could become more susceptible to mite infestations. This means that a diet with pyrethrums can make bees more resistant to mite infestations. Hence, C is correct.

The passage doesn't provide information given in the other options. They can thus be ignored.
