【正确答案】 B

【答案解析】Since b ＜ 0, 6b is negative, whereas b⁶ is
positive.
**Use TACTIC 1. Replace b with numbers satisfying b ＜ 0.

	Quantity A	Quantity B	Compare	· Eliminate
Let b = -1	6(-1) = -6	(-1)6 = 1	B is greater	A and C
Let b=-2	6(-2) = -12	(-2)6 = 64	B is greater

Both times Quantity B was greater: choose B.
