He sat under the shade of a tree.
He sat in the shade of a tree.
Why is the first sentence wrong?
This was a question on an exam where I was given a sentence to fill up with appropriate preposition. The question was:
He sat UNDER/IN/INTO/ON the shade of a tree.
The answer to this is IN the shade of a tree but I am not sure why? Because I marked UNDER the shade of a tree.
