Passage 23

Saturn’s giant moon Titan is the only planetary satellite with a significant atmosphere and the only body in the solar system other than Earth that has a thick atmosphere dominated by molecular nitrogen. For a long time, the big question about Titan’s atmosphere was how it could be so thick, given that Jupiter’s moons Ganymede and Callisto, which are the same size as Titan, have none. The conditions for acquiring and retaining a thick nitrogen atmosphere are now readily understood. The low temperature of the protosaturnian nebula enabled Titan to acquire the moderately volatile compounds methane and ammonia (later converted to nitrogen) in addition to water. The higher temperatures of Jupiter’s moons, which were closer to the Sun, prevented them from acquiring such an atmosphere.

1. According to the passage, Titan differs atmospherically from Ganymede and Callisto because of a difference in

A. rate of heat loss

B. proximity to the Sun

C. availability of methane and ammonia

D. distance from its planet

E. size

Passage 24

Observations of the Arctic reveal that the Arctic Ocean is covered by less ice each summer than the previous summer. If this warming trend continues, within 50 years the Arctic Ocean will be ice free during the summer months. This occurrence would in itself have little or no effect on global sea levels, since the melting of ice floating in water does not affect the water level. However, serious consequences to sea levels would eventually result, because __________.

1. Which of the following most logically completes the passage?

A. large masses of floating sea ice would continue to form in the wintertime

B. significant changes in Arctic sea temperatures would be accompanied by changes in sea temperatures in more temperate parts of the world

C. such a warm Arctic Ocean would trigger the melting of massive landbased glaciers in the Arctic

D. an ice-free Arctic Ocean would support a very different ecosystem than it does presently

E. in the spring, melting sea ice would cause more icebergs to be created and to drift south into shipping routes

Passage 25

In a recent study, David Cressy examines two central questions concerning English immigration to New England in the 1630s: what kinds of people immigrated and why? Using contemporary literary evidence, shipping lists, and customs records, Cressy finds that most adult immigrants were skilled in farming or crafts, were literate, and were organized in families. Each of these characteristics sharply distinguishes the 21,000 people who left for New England in the 1630s from most of the approximately 377,000 English people who had immigrated to America by 1700.

With respect to their reasons for immigrating, Cressy does not deny the frequently noted fact that some of the immigrants of the 1630s, most notably the organizers and clergy, advanced religious explanations for departure, but he finds that such explanations usually assumed primacy only in retrospect. When he moves beyond the principal actors, he finds that religious explanations were less frequently offered, and he concludes that most people immigrated because they were recruited by promises of material improvement.

For the following question, consider each of the choices separately and select all that apply.

1. The passage indicates that Cressy would agree with which of the following statements about the organizers among the English immigrants to New England in the 1630s?

A. Some of them offered a religious explanation for their immigration.

B. They did not offer any reasons for their immigration until some time after they had immigrated.

C. They were more likely than the average immigrant to be motivated by material considerations.

2. Select the sentence that provides Cressy’s opinion about what motivated English immigrants to go to New England in the 1630s.

“When … movement.”

3. In the passage, the author is primarily concerned with

A. summarizing the findings of an investigation

B. analyzing a method of argument

C. evaluating a point of view

D. hypothesizing about a set of circumstances

E. establishing categories
