Answer: Is the fertilizer supporting the growth of beetles?
Explanation:
Here, Kyle wants to get rid of beetles in his garden but he observes that in an area where there is fertilizer there are more beetles. Thus, Kyle can frame the hypothesis that, "Is the fertilizer supporting the growth of beetles?". This hypothesis is forming the basis of experimental trials that can be done on beetles who were exposed to fertilizer and those who were not in laboratory conditions to check whether fertilizer is effective in supporting the growth of beetles. If the fertilizer is useful in supporting the growth then it should not be used in the garden.
