Complete Question Explanation
Strengthen-CE. The correct answer choice is (A)
The conclusion of this argument can be found in the first sentence: being near woodlands promotes the health of crops. Why? Because bees visit flowers far from woodlands less often than they visit flowers close to woodlands. The question remains as to why the number of visits by the bees would have any effect on the plant's chance of being pollinated. Answer choice (A) provides the missing link between the premise and the conclusion.
Answer choice (A): This is the correct answer choice. If the likelihood of pollination is directly proportional to the number of visits by the bees, and bees typically visit flowers close to woodlands more often, it follows that being near the natural habitat of bees is beneficial to the plants.
Answer choice (B): This answer does the exact opposite of what is needed: it weakens the argument by stating that bees can be found elsewhere, and therefore plants may not need to be near woodlands to have a high chance of pollination.
Answer choice (C): If some pollinators are found outside of woodlands, this could weaken the argument in the same way answer choice (B) would. This answer choice is incorrect.
Answer choice (D): As with answer choices (B) and (C), this one weakens the argument by suggesting alternate ways for plants to get pollinated. If some pollinators tend to travel far, then perhaps it is not necessary that plants are situated close to the natural habitat of bees.
Answer choice (E): The fact that many crops that are not near woodlands depend on pollination is irrelevant to this argument, as it is unclear whether they receive sufficient pollination. Perhaps they do, which would weaken the argument here.
