Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 45. PHOBIAS CONTROL THE EYES People with an overpowering fear of something may not be able to consciously control the direction of their gaze when faced with a picture that provokes that fear. Those with a fear of spiders, or arachnophobia, may not be able to avoid looking toward a spider in the grass, while those without the fear can. To reach this finding, 26 college students - half of whom had arachnophobia - were outfitted with a device that tracks eye movements. The participants were then shown a four-by-four grid of flowers on a computer screen, where a picture of a grey-brown spider and a grey-brown mushroom each occupied one space on the grid. In one trial, the students were asked to press the spacebar when they spotted a mushroom, but to ignore any spiders. In a second, the students were asked to press the key when they saw the spider, but to avoid looking at mushrooms. When instructed to ignore the spider and spot the mushroom, the students with arachnophobia could not avoid looking at the spider - causing them to notice the mushroom three-tenths of a second more slowly than the control group. Additionally, when the students were asked to search for the spider, the arachnophobic students found the spider and pressed the space bar about three-tenths of a second more quickly than the non-phobic students. These findings show that the attention processes of people with a powerful fear of spiders may be beyond their conscious control. This suggests that treatments that focus on conscious thought processes may not work for such phobias. Instead, therapists could focus on treatments such as systematic desensitization. What was the function of the spacebar?

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions that follow.   Under certain circumstances, the human body must cope with gases at greater-than-normal atmospheric pressure. For example, gas pressures increase rapidly during a drive made with scuba gear because the breathing equipment allows divers to stay underwater longer and dive deeper. The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth in seawater, so that at 39 meters in seawater a diver is exposed to pressure of about 4 atmospheres. The pressure of the gases being breathed must equal the external pressure applied to the body, otherwise breathing is very difficult. Therefore all of the gases in the air breathed by a scuba diver at 40 meter are present at five times their usual pressure. Nitrogen, which composes 80 percent of the air we breathe, usually causes a balmy feeling of well-being at this pressure. At a depth of 5 atmospheres, nitrogen causes symptoms resembling alcohol intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct effect on the brain of the large amounts of nitrogen dissolved in the blood. Deep dives are less dangerous if helium is substituted for nitrogen, because under these pressures helium does not exert a similar narcotic effect.   As a scuba diver descends, the pressure of nitrogen on the lungs increases. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues The reverse occurs when the diver surfaces, the nitrogen pressure in the lungs falls and the nitrogen diffuses from the tissues into the blood, and from the blood into the lungs. If the return to the surface is too rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles are formed. They can cause severe pains, particularly around the joints.   Another complication may result if the breath is held during ascent. During ascent from a depth of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend and even rupture. This condition is called air embolism.   To avoid this event, a diver must ascend slowly, never at a rate exceeding the rise of the exhaled air bubbles, and must exhale during ascent. It can be inferred from the passage that which of the following presents the greatest danger to a diver?
