Question

Fill in the blank-Study hard ___you will not pass

Answer 1

1. The sentence follows the pattern "imperative, ___ consequence," which needs a word meaning "otherwise."
2. "Unless" would require restructuring the whole sentence, and "otherwise" reads awkwardly with only a comma before it.
3. "Else" fits directly after the imperative with just a comma, exactly as the sentence is written.

Correct answer: else.
