Answer:d- a small lake
Explanation:
As given in the paragraph rain seeps through rock and forms a vast aquifer.
An aquifer consists of permeable rocks or unconsolidated materials (sand, gravel, or slit ) that holds the water. This water can be extracted using a well.
Looking at the options bedroom and classroom are small as compared to the real-life aquifer so options a and b can be rejected.
option c must also be rejected as it is given rain forms vast aquifer. Vast here suggests the size of a lake.
So option d is correct.
The comma in the sentence above is used incorrectly because it <span>attempts to separate a compound predicate. The comma is incorrectly used to split a compound predicate which shares the same subject. The predicate must need equal access to the subject that's why no comma is needed.</span>
Much of this poverty was said to be "invisible." It affected Blacks in urban neighborhoods and whites in depressed rural areas like the Appalachian Mountains. Middle-class Americans never saw the misery in other sectors of American society. Poverty amid plenty was another paradox of the '50s, but most people were able to ignore it.
