[Q]: Background: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. Paragraph: Tim and Dan both studied reproduction in college. Dan studied plant reproduction while Tim studied fish reproduction. Given the paragraph above, please answer correctly the following question: Which person studied less about the way fish reproduce?
****
[A]: Dan

[Q]: Background: The brains of all mammals have a unique layer of nerve cells covering the cerebrum. This layer is called the neocortex (the pink region of the brains in Figure above ). The neocortex plays an important role in many complex brain functions. In some mammals, such as rats, the neocortex is relatively smooth. In other mammals, especially humans, the neocortex has many folds. The folds increase the surface area of the neocortex. The larger this area is, the greater the mental abilities of an animal. Paragraph: Two students read about brains in the animal kingdom. Tom read more about the brains of mammals, while Reed learned more about the brains of amphibians. Given the paragraph above, please answer correctly the following question: Which student learned more about the neocortex of rats?
****
[A]: Tom

[Q]: Background: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3) and phosphates (PO4) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally). Paragraph: Two dairy farms were supplying milk and other milk products to the surrounding counties. Sunny farm practiced organic farming and produced organic milk, while Cloud farm was into conventional milk production. Given the paragraph above, please answer correctly the following question: Which farm reduced their pesticide utilization?
****
[A]: Sunny

[Q]: Background: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection. Paragraph: Two bird islands experienced different levels of rainfall. West island experienced a lengthy drought that lasted several years. Many birds were affected by this drought. East island had several normal years as far as rainfall was concerned. Given the paragraph above, please answer correctly the following question: Which island had more birds with smaller beaks die in the drought?
****
[A]:
West
