• Question 142:

  One reason researchers have long believed that Mars never enjoyed an extensive period of warm and wet climate is that much of the surface not covered by wind-borne dust appears to be composed of unweathered material. If water flowed for an extended period, researchers reasoned, it should have altered and weathered the volcanic minerals, creating clays or other oxidized, hydrated phases (minerals that incorporate water molecules in their crystal structure).

  It turns out. though, that the scientists were not looking closely enough. New high- resolution mapping data and close-up surface studies have revealed clays and other hydrated minerals in many regions The clay deposits are scattered all over, in ancient volcanic surfaces and heavily cratered highland regions, some of which have apparently been exposed by erosion only recently.

  Consider each of the choices separately and select all that apply.

  The passage indicates which of the following about the clay deposits an Mars?

  A. They are widely distributed.
  B. They are not the only hydrated minerals on Mars.
  C. They have only recently been detected.
  A. They are widely distributed.
  B. They are not the only hydrated minerals on Mars.
  C. They have only recently been detected.

• Question 146:

  Economists use two competing models to describe the effects of commercial advertising--advertising as market competition and advertising as market power. The market competition model holds that the fundamental function of advertising is to provide information about products and brands. It is argued that information in ads permits greater marketplace efficiencies, such as lower prices and reduced monopoly power. In a similar vein, much discussion regarding political advertising has rested on its informational value Does political advertising provide political information and help voters make informed decisions'1 Nelson argues that promoting bars of soap in commercial ads is no different than promoting political ideas ideology from political candidates in political ads. on the grounds that information is being distributed m both cases. Others, such as Ferguson and Jamieson, disagree with Nelson's proposition Ferguson, for example, pointed out that choosing a political candidate is more like buying an experience good (where the quality is hard to evaluate prior to purchase) rather than a search good (where the quality is easily evaluated before the purchase). According to Ferguson, claims in political ads do not have true informational value, because it is difficult for voters to draw inferences about the future deeds of a candidate from what the ads say Furthermore. Jamieson argues that political ads reshape the public image of political candidates and change voters' feelings about the candidates with subtle emotional cues but without substantive information upon which to base a reasoned judgment

  Which of the following statements, if true, would most clearly weaken Nelson's argument as it is presented in the passage?

  A. Political advertisements that make false claims are subject to rebuttal by political advertisements for opposing candidates.
  B. Most producers of political advertisements work directly for the political campaigns of the candidates the advertisements promote.
  C. Soap advertisements typically rely on evocative images that do not relate to the effectiveness of the product being advertised.
  D. Advertisements for familiar products, such as bars of soap, are evaluated more critically by audiences than are advertisements for less familiar products.
  E. Voter disappointment in the candidates that they elect is analogous to the disappointment consumers of familiar products sometimes experience.
  D. Advertisements for familiar products, such as bars of soap, are evaluated more critically by audiences than are advertisements for less familiar products.

• Question 147:

  Carbon dating of charcoal gathered from a Nok iron smelter at Intini. Nigeria, suggests thai iron technology was established there by 410 B.C. This may not be the oldest smelter in sub-Saharan Africa, however. Archaeologists have located evidence of iron-smelting in the Termit Hills of Niger from as early as 1400 B.C.. but skeptics say the wood used for that dating could have already been centuries old when burned as fuel--a problem that dogs carbon dating, especially in arid places like Niger, where wood desiccates and lasts longer. Of course, the same problem could distort dates for the Intini furnace as well, but here there is an important piece of corroborating evidence: Nok pottery found inside the furnace alongside the charcoal

  The passage is primarily concerned with

  A. determining which of two ancient cultures in sub-Saharan Africa was more technologically advanced
  B. dating the development of iron technology in sub-Saharan Africa
  C. assessing certain advantages and disadvantages of carbon dating in sub-Saharan Africa
  D. suggesting a possible link between climate and technological development in sub- Saharan Africa
  E. contrasting the iron-smelting techniques of two civilizations in sub-Saharan Africa
  B. dating the development of iron technology in sub-Saharan Africa

• Question 150:

  The public has not reacted favorably to the majority of the policies adopted by the present government. If. however, the electoral landslide by which the government achieved power five years ago was. as is often claimed, a mandate for more conservative policies, then the public response to most of the government's policies would have been favorable.

  If the statements in the passage are true, which of the following must also be true on the basis of them?

  A. The public would have reacted more favorably to the policies adopted by the present government if those policies had been more conservative.
  B. Most of the people who voted for the present government would have voted for an opposition party if they had not been misled about the policies that would be adopted.
  C. None of the policies adopted by the present government to which the public has responded favorably are conservative policies.
  D. The electoral landslide by which the present government achieved power was not a mandate for more conservative policies.
  E. The present government will be voted out of office at the next election.
  D. The electoral landslide by which the present government achieved power was not a mandate for more conservative policies.
