问题 Steady advances in digital memory technology are making mass-storage devices technologically______ and increasingly cost-effective.

选项 A、eligible
B、sustainable
C、probable
D、feasible

答案D

解析 语义连贯题。feasible“可行的,能够完成的,能够实施的”,常形容plan,idea 或 method 等。 probable“可能发生或成为事实的”。我们常说在理论上可能,在技术上可行,当然理论上的可能是在先的。eligible“合格的”,sustainable“养得起的”。
