Which preposition properly completes the sentence?
A.
under
B.
to
C.
for
D.
on

D. on

The correct preposition to complete the sentence is D. on

To determine which preposition properly completes the sentence, you can analyze the meaning of each preposition and select the one that makes the most sense in context.

A. "Under" typically indicates a position beneath or below something. This does not fit the context of cattle grazing on an open range.

B. "To" typically indicates a direction or movement towards a specific location. While cattle may move towards an open range, it does not describe their current position or activity of grazing.

C. "For" typically indicates purpose or benefit. In this context, it does not accurately describe the relationship between cattle and the open range.

D. "On" typically indicates a position or location resting or being supported by something. Since cattle typically graze by moving around and eating the grass from the ground, "on" is the most appropriate preposition to complete the sentence.

Therefore, the correct preposition to complete the sentence is: D. "on".
