In the early years of television, Vladimir Zworykin was considered its inventor, at least
publicly. His loudest champion was his boss David Sarnoff, the president of RCA and the
“father of television,” as he was and is widely regarded. Modern historians agree that Philo
Farnsworth, a self-educated prodigy who was the first to transmit live images, was television's
technical inventor. But Farnsworth's contributions have gone relatively unnoticed, since it was
Sarnoff, not Farnsworth, who put televisions into living rooms and, even more importantly,
who successfully borrowed from the radio industry the paradigm of advertiser-funded
programming, a paradigm still dominant today. In contrast, Farnsworth lacked business sway
and was unable to realize his dream of television as an educational tool.
Perhaps Sarnoff simply adapted his business ideas from other industries such as newspapers,
for instance, replacing the revenue from subscriptions and newsstand purchases with that of
television set sales, but Sarnoff promoted himself as a visionary. Some critics argue that
Sarnoff’s construct has damaged programming content. Others contend that it merely created
a democratic platform allowing audiences to choose the programming they desire.
The primary purpose of the passage is to
(A) correct public misconception about Farnsworth’s role in developing early television
programs
(B) debate the influence of television on popular culture
(C) challenge the current public perception of Vladimir Zworykin
(D) chronicle the events that led from the development of radio to the invention of the
television
(E) describe Sarnoff’s influence on the public perception of televisions inception, and debate
the impact of Sarnoff’s paradigm
答案：E
It can be inferred from the second paragraph of the passage that
(A) television shows produced by David Sarnoff and Vladimir Zworykin tended to earn
negative reviews
(B) educational programs cannot draw as large an audience as sports programs
(C) a number of critics feel that Sarnoff’s initial decision to earn television revenue through
advertising has had a positive or neutral impact on content
(D) educational programs that are aired in prime time, the hours during which the greatest
number of viewers are watching television, are less likely to earn a profit than those that are
aired during the daytime hours
(E) in matters of programming, the audiences preferences should be more influential than
those of the advertisers
答案：C
Because of the proximity and likeness of Mars to Earth, scientists have long speculated about
the possibility of life on Mars. Roughly three centuries ago, astronomers observed Martian
polar ice caps, and later scientist’s discovered other similarities to Earth, including length of
day and axial tilt. But in 1965, photos taken by the Mariner 4 probe revealed a Mars without
rivers, oceans or signs of life. Moreover, in the 1990s, it was discovered that unlike Earth,
Mars no longer possessed a substantial global magnetic field, allowing celestial radiation to
reach the planet's surface and solar wind to eliminate much of Mars's atmosphere over the
course of several billion years. More recent probes have investigated whether there was once
liquid water on Mars. Some scientists believe that the presence of certain geological
landforms definitively resolves this question. Others posit that wind erosion or carbon dioxide
oceans may be responsible for these formations. Mars rovers Opportunity and Spirit, which
landed on Mars in 2004, have both discovered geological evidence of past water activity.
These findings substantially bolster claims that there was once life on Mars.
The passage is primarily concerned with which of the following?
(A) Disproving a widely accepted theory.
(B) Initiating a debate about the possibility of life on Mars.
(C) Presenting evidence in support of a controversial claim.
(D) Describing the various discoveries made concerning the possibility of life on Mars.
(E) Detailing the findings of the Mars rovers Opportunity and Spirit.
答案：D
It can be inferred from the passage that which of the following characteristics of a planet
would imply that it might support life? Select all that apply.
A. A significant global magnetic field
B. Evidence of liquid carbon-dioxide on the planet’s surface
C. A size roughly approximating that of Earth
答案：A B

As to when the first people populated the American subcontinent is hotly debated. Until recently, the Clovis people, based on evidence found in New Mexico, were thought to have been the first to have arrived, some 13,000 years ago. Yet evidence gathered from other sites suggest the Americas had been settled at least 1,000 years prior to the Clovis. The "Clovis first" Idea, nonetheless, was treated as gospel, backed by supporters who, at least initially outright discounted any claims that suggested precedence by non-Clovis people. While such a stance smacked of fanaticism, proponents did have a solid claim: if the Clovis peoples crossed the Bering Strait 13,000 years ago, only after it had become ice-free, how would a people have been able to make a similar trip but over ice?
A recent school of thought, backed by Weber, provides the following answer: pre-Clovis people reached the Americas by relying on a sophisticated maritime culture, which allowed them to take advantage of refligia, or small areas in which aquatic life flourished. Thus they were able to make the long journey by hugging the coast as far south as to what is today British Columbia. Additionally, they were believed to have fashioned a primitive form of crampon so that they would be able to dock in these refligia and avail themselves of the microfauna. Still, such a theory begs the question as to how such a culture developed.
The Solutrean theory has been influential in answering this question, a fact that may seem paradoxical — and startling — to those familiar with its line of reasoning: the Clovis people were actually Solutreans, an ancient seafaring culture along the Iberian peninsula, who had _ astoundingly given the time period — crossed into the Americas via the Atlantic ocean. Could not a similar Siberian culture, If not the pre-Clovis themselves, have displayed equal nautical sophistication?
Even if one subscribes to this line of reasoning, the “Clovis first” school still have an objection: proponents of a pre-Clovis people rely solely on the Monte Verde site in Chile, a site so far south that its location begs yet another question: What of the 6,000 miles of coastline between the ice corridor and Monte Verde? Besides remains found in network of caves in Oregon, there has been scant evidence of a pre-Clovis peoples. Nonetheless, Meade and Pizlnsky claim that a propitious geologic accident could account for this discrepancy: Monte Verde was located near a peat bog that essentially fossilized the village. Archaeologists uncovered two wooden stakes, which, at one time, were used in twelve huts. Furthermoreplant species associated with areas 150 miles away were found, suggesting a trade network. These findings indicate that the Clovis may not have been the first to people the Americas, yet more excavation, both in Monte Verde and along the coast, must be conducted in order to determine the extent of pre-Clovis settlements in the Americas.
It can be inferred from the passage that the reason the author finds the Solutrean hypothesis both startling and paradoxical is that
(A) ancient cultures were in most likelihood unable to develop such a sophisticated form of maritime transport that they were able to cross the Atlantic
(B) it supports the Clovis school of thought, and posits the existence of a capacity not commonly associated with ancient people
(C) the Clovis people had crossed from Siberia navigating across a difficult ice corridor, whereas the pre-Clovis people had sailed, with far less difficulty, across the Atlantic
(D) it suggests that the pre-Clovis people had a way to circumvent the ice-corridor, yet were unlikely to have traveled as far south as modem day Chile
(E) it runs counter to one of the chief tenets of the "Clovis first" school of thought 答案：C
It can be most reasonably inferred from the passage that in regard to the manner in which the
Monte Verde village was preserved that
(A) unless evidence of other pre-Clovis people was fossilized the same way it was in Monte Verde, archaeologists will be unable to determine the extent of the settlement of pre-Clovis people
(B) major discoveries can sometimes result from random processes in the environment
(C) plant species can offer valuable dues into the origin of other pre-Clovis settlements
(D) sites dated from slightly after the period of the Clovis people did not offer archaeologists such a trove of information
(E) archaeologists are unlikely to find any other significant ev idence of pre-Clovis people unless they venture as much as 150 miles from the site
答案：E
If it is true that a trade network between pre-Clovis people had been established, then which
of the following could be expected to be found at settlements near Monte Verde?
(A) Other villages that have been preserved in a peat bog
(B) Plants species similar to those uncovered at Monte Verde
(C) The same number of wooden stakes for supporting dwelling
