多选题A piece of first-year ice will taste salty.

In the context in which it appears, "fine" most nearly means A. acceptable. B. elegant. C. precise. D. pure. E. small.

多选题A mysterious phenomenon is the ability of {{U}}over-water migrants{{/U}} to travel on course. Birds, bees, and other species can keep track of time without any sensory cues from the outside world, and such "biological clocks" clearly contribute to their "compass sense". For example, they can use the position of the Sun or stars, along with the time of day, to find north. But compass sense alone cannot explain how birds navigate the ocean: after a flock traveling east is blown far south by a storm, it will assume the proper northeasterly course to compensate. Perhaps, some scientists thought, migrants determine their geographic position on Earth by celestial navigation, almost as human navigators use stars and planets, but this would demand of the animals a fantastic map sense. Researchers now know that some species have a magnetic sense, which might allow migrants to determine their geographic location by detecting variations in the strength of the Earth's magnetic field. The main idea of the passage is that: A. migration over land requires a simpler explanation than migration over water does. B. the means by which animals migrate over water are complex and only partly understood. C. the ability of migrant animals to keep track of time is related to their {{U}}magnetic sense{{/U}}. D. knowledge of geographic location is essential to migrants with little or no {{U}}compass sense{{/U}}. E. explanations of how animals migrate tend to replace, rather than build on, one another.

多选题Recently some scientists have concluded that meteorites found on Earth and long believed to have a Martian origin might actually have been blasted free of Mars's gravity by the impact on Mars of other meteorites. {{U}}This conclusion has led to another question:{{/U}} whether meteorite impacts on Earth have similarly driven rocks from this planet to Mars. According to astronomer S.A. Phinney, kicking a rock hard enough to free it from Earth's gravity would require a meteorite capable of making a crater more than 60 miles across. Moreover, even if Earth rocks were freed by meteorite impact, Mars' orbit is much larger than Earth's, so Phinney estimates that the probability of these rocks hitting Mars is about one-tenth as great as that of Mars' rocks hitting Earth. To demonstrate this estimate, Phinney used a computer to calculate where 1,000 hypothetical particles would go if ejected from Earth in random directions. He found that 17 of the 1,000 particles would hit Mars. The passage is primarily concerned with A. presenting an argument to support a particular hypothesis. B. suggesting an answer to a theoretical question. C. questioning the assumptions of a research project. D. criticizing experimental results. E. explaining the origin of certain scientific data.

多选题From the 1900's through the 1950's waitresses in the United States developed a form of unionism based on the unions' defining the skills that their occupation included and enforcing standards for the performance of those skills. {{U}}This "occupational unionism" differed substantially from the "worksite unionism" prevalent among factory. workers.{{/U}} Rather than unionizing the workforces of particular employers, waitress locals sought to control their occupation throughout a city. Occupational unionism operated through union hiring halls, which provided free placement services to employers who agreed to hire their personnel only through the union. Hiring halls offered union waitresses collective employment security, not individual job security—a basic protection offered by worksite unions. That is, when a waitress lost her job, the local did not intervene with her employer but placed her elsewhere; and when jobs were scarce, the work hours available were distributed fairly among all members rather than being assigned according to seniority. The author of the passage mentions "particular employers" primarily in order to A. suggest that occupational unions found some employers difficult to satisfy. B. indicate that the occupational unions served some employers but not others. C. emphasize the unique focus of occupational unionism. D. accentuate the hostility of some employers toward occupational unionism. E. point out a weakness of worksite unionism.
