(1) d + 0.01 < 2
(2) d + 0.05 > 2
(1) d + 0.01 < 2

A. Statement (1) ALONE is sufficient but statement (2) ALONE is not sufficient.
B. Statement (2) ALONE is sufficient but statement (1) ALONE is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are not sufficient.
正解：
Statement (1) indicates that d<1.99, which means that the tenths’ digit could be any of the ten digits. Therefore, the answer must be B, C, or E. Statement (2) indicates that d > 1.95. Since it is given that d<2, the tenths’ digit of d must be 9. The best answer is B.
