QUESTION #2


Because there is no research clue given in the question stem, the best strategy for this all-that-apply Inference question is to check each choice against the information presented in the passage. (A) is supported by the first two sentences; ice floats on water because it is less dense than water, which results from the property that water expands when it freezes. The first sentence describes water as being “among the few substances” that do this, so it can be reasonably inferred that most substances do not. (B) is also supported by the second sentence; the lower density of ice directly causes it to float, so anything with a lower density can likewise be expected to float. (C), on the other hand, is contradicted by the second paragraph. The passage cites two reasons why the melting of ice caps would cause sea level rise: the land mass described in (C) and the difference in density between sea water and fresh water. Even if the Antarctic ice were not supported by land, the difference in density would still be sufficient to cause a rise in sea level. (C), therefore, is incorrect.

QUESTION #3


The passage provides four facts to fully explain the phenomenon in question, each of which corresponds to one of the four incorrect answers. The fact that water is rare among compounds in that it expands when it freezes corresponds to choice (A). The notion that the southern ice cap rests on a land mass, indicating that the scientific principles mentioned in the first paragraph do not apply in this case, matches up with (B). (C) is not present in the passage, as there is no mention of a specific event in the passage. Thus, it is the correct answer. The difference between salty ocean water and fresh water causing greater buoyancy allows elimination of (D). Finally, the description of differences in density causing the buoyant force is represented by (E).
