This Question is Easy if one knows the meaning of Harvesting .i.e. is cutting the trees. So the question gave a relationship that both wild mushroom and a tree are mutually beneficial .So dont cut them.and we have to weaken it that is to state that removing mushroom actually helps.one way to think of it is that cutting the mushroom plant has other benifits to the Host tree,like wild mushroom attracts bacteria ,or to state what option D has said that is if we remove mushroom then it attracts even more mushrooms to grow .since the question has given a positive relationship between mushroom and host tree so it is easily inferable.
good catch. it is easy to find correct answer if he /she knows the meaning of harvesting

Q1. Brothers Inc, a construction company, spends significant time and money to dismantle older houses piece by piece in order to reuse the wood. Although the company does earn a net profit despite these expenditures, the company could earn even more by adopting a new policy. Brothers’ new land contains hundreds of trees that are already slated to be razed; the company should use those trees for wood instead of the old houses Which of the following, if true, most strongly supports Brothers’ policy to reuse wood? (A) It is a waste of resources for a company that needs wood to chop down hundreds of trees but not use the wood. (B) There is virtually no difference in quality between wood reclaimed from older houses and wood processed from newly-chopped trees. (C) Sawmills can reshape previously used wood much more quickly and cost-effectively than it can shape whole trees. (D) It would cost the company less to use the trees it already owns than to pay to dismantle homes for previously used wood. (E) The number of older houses available for dismantling is growing steadily

Q2. The chanterelle, a type of wild mushroom, grows beneath host trees such as the Douglas fir, which provide it with necessary sugars. The underground filaments of chanterelles, which extract the sugars, in turn provide nutrients and water for their hosts. Because of this mutually beneficial relationship, harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree. Which of the following, if true, casts the most doubt on the conclusion drawn above? (A) The number of wild mushrooms harvested has increased in recent years. (B) Chanterelles grow not only beneath Douglas firs but also beneath other host trees. (C) Many types of wild mushrooms are found only in forests and cannot easily be grown elsewhere. (D) The harvesting of wild mushrooms stimulates future growth of those mushrooms. (E) Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments.
CR Questions March - 6 :Q1. Pharmaceutical manufacturers have long claimed that one of the main reasons they give doctors free drug samples is so that doctors can pass the medicine along to poor patients. However, a new study shows that high-income, well-insured individuals receive considerably more prescription drug samples than do low-income, poorly insured individuals. This is because doctors favor affluent people with health insurance.
Which of the following, if true, most seriously jeopardizes the validity of the explanation for why high-income individuals receive more free prescription drug samples than low-income individuals do?
(A) Independent medical clinics not affiliated with large hospitals receive only a small percentage of the free drug samples distributed by pharmaceutical manufacturers.
(B) Because of the associated costs, low-income people see doctors less often, if at all.
(C) Some medical offices refuse to treat individuals for conditions that are not critical or life-threatening if the individual does not have the means to pay for the treatment.
(D) Once the free drug sample supply in a doctor’s office is gone, the patients are forced to pay for their prescriptions.
(E) Though they claim to give doctors free drug samples in order to help poor patients, the real reasons pharmaceutical companies do it are to increase brand awareness and to influence the doctor to prescribe these drugs more often.
Q2. Studies show that families in which both the husband and the wife are working normally tend to be single-child families. It is commonly understood that
such partners prefer to have only one child because of the lack of time on their hands to raise more than one child. However, other studies have shown that in households that have both the husband and wife working but that have more than one child, the partners married each other in their early twenties. Since
majority of the working parents in single-child households marry post the age of thirty-five, it is clear that the real reason such families have only one child is the age of the parents that does not biologically allow them to have more than one child.
