　　(A)

　　(B)

2014年6月15日SAT考试官方每日一题答案：B

解析：The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Four of the answer choices can be eliminated because each set of three numbers can be the lengths of three sides of a triangle. For example, in the third choice , the sum of any two numbers is greater than the third number. However, the second choice cannot be the lengths of the sides of a triangle, since is not greater than . This choice is the correct answer, since the question asked which set of numbers could NOT be lengths of the sides of a triangle.

2014年6月16日SAT考试官方每日一题答案：B

解析：Choice (B) is correct. If these terms were inserted into the sentence, the sentence would read, “While a 'rock' is usually defined as an aggregate, or combination, of one or more minerals, geologists often extend the definition to include such materials as clay, loose sand, and certain limestones.” An “aggregate” is the sum total of a combination of things, so a “rock” is an aggregate of one or more minerals. In addition to minerals, geologists feel confident including other materials such as “clay, loose sand, and certain limestones” in their definition of a rock; they “extend,” or broaden, the definition.
