Question

1. which word from the passage is closest in meaning to \porous\ as used in the sentence \porous and permeable rocks like sandstone and limestone make excellent aquifers\?

a. permeable (allows fluids to pass through)
b. full
c. dense
d. hard

Explanation:

The question asks for the synonym of "porous" in the given context. "Porous" means having small holes that allow liquids/gases to pass through. The sentence pairs "porous and permeable," and option A defines "permeable" as "allows fluids to pass through," which matches the meaning of porous. Other options (full, dense, hard) are unrelated to the concept of having passages for fluids.

Answer:

A. Permeable (allows fluids to pass through)
