Real Estate Agent: Next year, the occupancy rate for residential rental properties in Riverton will increase despite projections of decreasing population in the city.

Q. The boldfaced statements (underlined) in the argument above play which of the following roles?
A careful review of hospital fatalities due to anesthesia during the last 20 years indicates that the most significant safety improvements resulted from better training of anesthetists. Equipment that monitors a patient’s oxygen and carbon dioxide levels was not available in most operating rooms during the period under review. Therefore, the increased use of such monitoring equipment in operating rooms will not significantly cut fatalities due to anesthesia.
Q. A flaw in the argument is that
College football recruiting services rank incoming players on a scale of 1-star (not a highly sought-after prospect) to 5-star (considered to be the best players). Recently a service attempted to validate its rankings by assigning star ratings to players upon completion of their careers to determine the accuracy of the initial rankings. The survey averaged the post-career ratings of each player and found that 5-star players’ final average was 4.46, compared with 3.98 for 4-stars and 3.11 for 3-stars. This suggests that the rankings services do not effectively judge high-end talent as well as they judge players in the middle of the range.
Q. Which of the following identifies a problem with the service’s attempt to validate its rankings?
A severe illness which affects the red blood cell count has been found to be hereditary. Fifty percent of those who are diagnosed with the illness have a parent who suffers from it.

Q. Which of the following, if true, would most weaken the conclusion drawn by the known scientist?
Passage
Film scholars agree that Hollywood portrayals of America at war follow a cyclical pattern. During and immediately after a conflict, important films trumpet glory and sacrifice. Ten to fifteen years later, questioning and sometimes pacifistic movies about the conflict dominate. In the late 1960’s, “the raging bulls” of Hollywood—the young trendsetters rising to prominence—proclaimed this pattern obsolete. However, the passage of time has demonstrated this cultural pattern to be more resilient than it seemed in those days of social change.
Throughout the majority of the last century, evidence of the cyclical portrayal of war in film abounds. After America declared war against Germany during World War I, the still infant film industry glorified the fight against “the Hun.” By the early 1930’s, major releases had changed their tone; for example, All Quiet on the Western Front put forth an anti-war message by displaying the horrors of combat. After World War II began, the industry shifted gears. Suddenly, important pictures again portrayed glories and courage without the questioning or despair. For example, Guadalcanal Diary, produced during the war, showed “the ultimate sacrifice” as a noble and undoubted good. Once again, though, by 1957, films such as The Bridge on the River Kwai won awards for depicting the moral confusion of war.
Those who later declared this pattern dead based their conviction on their hearts rather than their minds. During the Vietnam War, the only major film about that conflict was The Green Berets, starring John Wayne and far closer in tone to Guadalcanal Diary than to The Bridge on the River Kwai. Similarly, years went by before more complex visions of war, such as Apocalypse Now, and then Platoon, emerged.
While today’s film industry is more diverse and its audience more culturally fragmented, this cycle largely continues. Jarhead, a layered depiction of the first gulf war, premiered more than ten years after that conflict. Further evidence of this pattern can be seen in the release of Apocalypse Now Redux, which contained additional footage that the producers originally thought would repel audiences. Thus, the famous aphorism “The more things change, the more they stay the same” certainly applies to this aspect of the film industry.
Q. According to the passage, Apocalypse Now Redux differed from Apocalypse Now in which of the following ways?

Q. What is the main point made by the author?
A survey of charitable giving in the state found that the average dollar amount contributed annually by residents of urban areas to programs for the homeless was $15 greater than the amount contributed by residents of rural areas.

Q. EACH of the following, if true, casts doubt on the conclusion of the survey’s creators EXCEPT
A small percentage of dogs are believed to be able to detect the onset of seizures in their owners. A dog with this ability will display characteristic behaviors, such as staring intently at its owner, just before a seizure occurs. Observations of epilepsy patients do not reveal any noticeable change in odor, behavior, or appearance before a seizure. However, seizure-detecting dogs can predict a seizure even when the patient is in another room.
Q. If the statements above are true, which of the following is most strongly supported by them?
