　　Directions: Compare Quantity A and Quantity B, using additional information centered above the two quantities if such information is given, and select one of the following four answer choices:

　　(A) Quantity A is greater.

　　(B) Quantity B is greater.

　　(C) The two quantities are equal.

　　(D) The relationship cannot be determined from the information given.

　　(A) Quantity A is greater.

　　(B) Quantity B is greater.

　　(C) The two quantities are equal.

　　(D) The relationship cannot be determined from the information given

　　答案解析：

　　For the integers greater than 24, note that 25, 26, 27, and 28 are not prime numbers, but 29 is a prime number, as are 31 and many other greater integers. Thus, 29 is the least prime number greater than 24, and Quantity A is 29. For the integers less than 28, note that 27, 26, 25, and 24 are not prime numbers, but 23 is a prime number, as are 19 and several other lesser integers. Thus, 23 is the greatest prime number less than 28, and Quantity B is 23. Thus, the correct answer is Choice A, Quantity A is greater.
