TASK DEFINITION: In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.
PROBLEM: Passage: Steve MacKendrick, nicknamed "Canada" because he claims he is from there, volunteers in 1940 for the British military's parachute training facility. He obviously has a good deal more experience and leadership skills than he lets on. Canada tries to become better acquainted with a pretty parachute rigger named Penny Gardner. She is initially put off by his attitude, but they eventually start dating. Both Penny and his new commander, Major Snow, see potential (and a mystery that does not add up) in him, despite his strong efforts to avoid assuming any responsibility. Canada turns down Snow's offer to send him to officer school.
After completing parachute school, Canada's unit goes on a raid on the German radar station at Bruneval. An RAF radar expert, Flight Sergeant Box, accompanies the raiders to retrieve a key component to take back to Britain. The mission is a success, but Corporal Dawes, one of the men in Canada's outfit, hurts both his legs in the drop. 
Back in Britain, after visiting Dawes, Canada is recognised by an American airman. He tells Penny that he resigned his commission from the USAAF after ordering his best friend and co-pilot to parachute out of their bomber when an experimental rocket got stuck. His friend was killed when his parachute did not open properly. Canada blamed himself and refuses any responsibility that might endanger anyone's life. When Snow confronts Canada with what he has learned (from a security investigation that he has ordered), Canada wrongly assumes that Penny told what she learned, and he breaks up with her. 
Question: Who does Canada believe the parachute rigger tells his USAAF story too?

SOLUTION: Major Snow.

PROBLEM: Passage: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?

SOLUTION: Broderick.

PROBLEM: Passage: Libby's original exchange reservoir hypothesis assumed that the 14C/12C ratio in the exchange reservoir is constant all over the world, but it has since been discovered that there are several causes of variation in the ratio across the reservoir.Marine effect
The CO2 in the atmosphere transfers to the ocean by dissolving in the surface water as carbonate and bicarbonate ions; at the same time the carbonate ions in the water are returning to the air as CO2. This exchange process brings14C from the atmosphere into the surface waters of the ocean, but the 14C thus introduced takes a long time to percolate through the entire volume of the ocean. The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven. The main mechanism that brings deep water to the surface is upwelling, which is more common in regions closer to the equator. Upwelling is also influenced by factors such as the topography of the local ocean bottom and coastlines, the climate, and wind patterns. Overall, the mixing of deep and surface waters takes far longer than the mixing of atmospheric CO2 with the surface waters, and as a result water from some deep ocean areas has an apparent radiocarbon age of several thousand years. Upwelling mixes this "old" water with the surface water, giving the surface water an apparent age of about several hundred years (after correcting for fractionation). This effect is not uniform – the average effect is about 400 years, but there are local deviations of several hundred years for areas that are geographically close to each other. These deviations can be accounted for in calibration, and users of software such as CALIB can provide as an input the appropriate correction for the location of their samples.  The effect also applies to marine organisms such as shells, and marine mammals such as whales and seals, which have radiocarbon ages that appear to be hundreds of years old.Hemisphere effect
The northern and southern hemispheres have atmospheric circulation systems that are sufficiently independent of each other that there is a noticeable time lag in mixing between the two. The atmospheric 14C/12C ratio is lower in the southern hemisphere, with an apparent additional age of about 40 years for radiocarbon results from the south as compared to the north. This is because the greater surface area of ocean in the southern hemisphere means that there is more carbon exchanged between the ocean and the atmosphere than in the north. Since the surface ocean is depleted in 14C because of the marine effect, 14C is removed from the southern atmosphere more quickly than in the north.  The effect is strengthened by strong upwelling around Antarctica.Other effects. 
Question: What is lower in atmosphere of the southern hemisphere?

SOLUTION:
14C/12C ratio.
