Question

Fill in the blank.

It was a fine June day, brilliant ______ sunlight.

• A. through
• B. by
• C. with
• D. in

Hint:

Think of a preposition that means "filled with" or "covered by".

Answer 1

The Correct Option is C

This question checks which preposition correctly pairs with "brilliant" to describe a day that is bright because of sunlight. We look at the meaning each option would create.

1. through: "Brilliant through sunlight" suggests something is seen "through" the sunlight, as if looking across a beam of light, which does not match the idea of a day being bright with light.
2. by: "By" usually shows an agent or a means, close to "next to" or "before a time". "Brilliant by sunlight" does not naturally describe a day filled with light.
3. with: "With" is used to show that something is filled by, covered by, or accompanied by something else. "Brilliant with sunlight" means the day was bright, full of sunlight, which matches the meaning of the sentence perfectly.
4. in: "In" usually shows location or a time period, such as "in June" or "in the room". "Brilliant in sunlight" reads oddly here, since it treats sunlight like a place rather than the reason the day was bright.

The correct preposition is "with", since it correctly conveys that the day was filled with bright sunlight.

Let's summarize:

• "With" is used when something is covered by or filled with another thing.
• The sentence describes a day that is bright because of sunlight, so "brilliant with sunlight" is the natural, idiomatic phrase.

So the correct word to fill the blank is "with", making option (c) the correct answer.
