Which choice completes the text with the most logical and precise word or phrase?

A

scarcity

B

abundance

C

quality

D

expansion

Correct Answer: A

Choice A is the best answer. The text uses "However" to introduce a limitation. The "limits" on power are caused by a lack of space. "Scarcity" means the state of being scarce or in short supply.

Choice B is incorrect because "abundance" means plenty. Choice C is incorrect because "quality" refers to the standard. Choice D is incorrect because "expansion" refers to growth.
