Question

Choose the correct option out of the four choices given.
Religious leaders should not delve _______ politics.

• A. in
• B. with
• C. at
• D. into

Hint:

The verb once meant to dig with a spade, and a spade goes inside the earth. That calls for a preposition of movement, not of position.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
We need the preposition that goes with "delve". The two live candidates are "in" and "into", so the question really tests whether we can tell a position preposition from a movement preposition.

Step 2: Key Formula or Approach:
Use the position and movement rule. "In" answers where something already is: the keys are in the drawer. "Into" answers where something is heading: he put the keys into the drawer. So look at whether the verb describes a state or an act of entering.

Step 3: Detailed Explanation:
Go back to the literal sense. "Delve" is an old word for digging with a spade, and a spade goes into the earth. The action is entry, not rest.
The modern figurative sense keeps that motion. A historian delves into old records, a reporter delves into a scandal. In each case somebody drives down inside a body of material to bring something out.
Since the verb describes entering, the movement preposition "into" is the one that fits, and "in" is ruled out because it would freeze the action into a position.
"With" is a different relation altogether. It names a companion or an instrument, as in "dig with a spade". Politics is the material being dug through, not the spade, so it fails.
"At" places the action at a single point, like "aim at the target". Delving is not a point action, it goes down through a subject, so it fails too.
Substituting gives "Religious leaders should not delve into politics", meaning they should not involve themselves deeply in political matters.

Step 4: Final Answer:
A verb of entering takes the movement preposition, so the answer is option (D), into.
