Show answer & explanation
Correct answer: A
Explanation
Sentence: “He is so weak to lift the box.”
Error: The structure “so + adjective + to + verb” is incorrect.
Rule:
The correct structure is:
So + adjective + that + clause
Example:
He is so weak that he cannot lift the box.
“Such” is used with nouns, but “so” is used with adjectives.
Correct construction:
He is so weak that he cannot lift the box.
Therefore, correct answer: that he cannot lift the box.
