Nobody should intrude ____ other's personal matter.

Question: Nobody should intrude ____ other's personal matter.

Correct Answer: into

Explanation:

The word "intrude" is a verb that commonly pairs with the preposition "into" to form the phrasal verb "intrude into." This pairing implies entering a situation or place where one is not wanted, expected, or invited. Here, the sentence "Nobody should intrude ____ other's personal matter." signifies the need to avoid meddling in someone else's business.

Let's break down the choices to understand why "into" is correct and the others are not:

1. In: While "in" is typically used to indicate location or position within something (e.g., "He is in the room"), it does not convey the sense of entering or crossing a boundary, which is essential in the context of "intruding."

2. Into: The preposition "into" suggests movement from outside to a point within. The phrase "intrude into" effectively captures the action of entering someone else's personal matters uninvited, making this the correct choice.

3. To: The preposition "to" generally indicates direction toward a destination or object (e.g., "going to school"). However, it does not carry the meaning of crossing a boundary or inserting oneself where one is not supposed to be.

4. With: The preposition "with" denotes accompaniment or association (e.g., "She is with her friend"). It does not match the context implying the interruption or invasion suggested by "intrude."

Hence, in the sentence "Nobody should intrude ____ other's personal matter," the preposition that accurately conveys the intended meaning is "into."
