Problem: Background: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. Paragraph: Two farms were situated on opposite banks of a large river flowing into the ocean. Hill farm practiced conventional agriculture, while Dew farm practiced permaculture design within the context of organic farming. Given the paragraph above, please answer correctly the following question: Which farm generated fewer marine dead zones because of fertilizer and chemical use?

A: Dew

Problem: Background: White blood cells also make chemicals that cause a fever. A fever is a higher-than-normal body temperature. Normal human body temperature is 98.6F (37C). Most bacteria and viruses that infect people reproduce fastest at this temperature. When the temperature is higher, the pathogens cannot reproduce as fast, so the body raises the temperature to kill them. A fever also causes the immune system to make more white blood cells. In these ways, a fever helps the body fight infection. Paragraph: Stephanie is a nurse at the local high school. Recently, the flu has been going around and she has had many students come into her office feeling ill. When a student comes in, the first thing she does is check their temperature to test for a fever. A research facility is testing the immune response of patients with immune deficiency who are infected with a virus. Some of the patients are given a trial of a new medication that is supposed to increase their immune system's response to illness while others are in the control group. Given the paragraph above, please answer correctly the following question: If a patient taking the medication has a higher white blood cell count than a patient in the control group is their body temperature higher or lower?

A: higher

Problem: Background: The benefits provided by no-tillage to predators may lead to larger predator populations, which is a good way to control pests (biological control), but also can facilitate predation of the crop itself. In corn crops, for instance, predation by caterpillars can be higher in no-till than in conventional tillage fields.In places with rigorous winter, untilled soil can take longer to warm and dry in spring, which may delay planting to less ideal dates. Another factor to be considered is that organic residue from the prior year's crops lying on the surface of untilled fields can provide a favorable environment to pathogens, helping to increase the risk of transmitting diseases to the future crop. And because no-till farming provides good environment for pathogens, insects and weeds, it can lead farmers to a more intensive use of chemicals for pest control. Other disadvantages of no-till include underground rot, low soil temperatures and high moisture.Based on the balance of these factors, and because each farm has different problems, agroecologists will not attest that only no-till or complete tillage is the right way of farming. Yet, these are not the only possible choices regarding soil preparation, since there are intermediate practices such as strip-till, mulch-till and ridge-till, all of them just as no-till categorized as conservation tillage. Agroecologists, then, will evaluate the need of different practices for the contexts in which each farm is inserted. Paragraph: Two farmers, Tom and Brad, applied different farming methods. Tom tilled his land, while Brad applied the no-till gardening method. Given the paragraph above, please answer correctly the following question: Which farmer had a soil that took longer to dry in spring?

A: Brad

Problem: Background: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. Paragraph: A scientist studied the effects of alcoholic beverages on the human body during severe weather exposure. He decided to experiment on himself. He stood in -30 degrees weather for 2 hours and called it experiment A. He then repeated the experiment, the only difference being that he consumed a pint of hard liquor before and during those two hours, and that was called experiment B. Given the paragraph above, please answer correctly the following question: When did the scientist's blood vessels dilate less, during experiment A, or during B?

A:
experiment A
