Answer 1

in?......................

Answer 2

In the given sentence, the correct preposition to use depends on the intended meaning. Here's a breakdown of each preposition:

1. On: "On the evening you must play the violin" implies that there is a specific evening on which you have a scheduled violin performance.

2. In: "In the evening you must play the violin" suggests that playing the violin is a regular activity that typically takes place during the evening hours.

3. At: "At the evening you must play the violin" is not a grammatically correct phrase. We do not use "at" before "evening" in this context.

The most common and natural choice would be to use "in the evening." This indicates that playing the violin generally happens during the evening hours.
