Question : Directions: In the following question, the sentence given with a blank is to be filled in with an appropriate word. Select the correct alternative out of the four.
____ you work hard, you cannot succeed.
Option 1: if
Option 2: Till
Option 3: Until
Option 4: Unless
Correct Answer: Unless
Solution : The fourth option is the appropriate answer in the sentence because 'unless' means 'if... not' and completes the phrase, which explains that if we do not work hard, we won't succeed.
Other options are contextually unfit for the sentence. Therefore, the complete statement should be " Unless you work hard, you cannot succeed."
