In today’s quiz, we’re focusing on modal verbs and how they shape the meaning of sentences. Take a look at this sentence:

“You ______ have bothered coming. I’ve already finished it.”

You have three possible answers:

• A. mustn’t
• B. wouldn’t
• C. needn’t

Each of these options changes the meaning of the sentence, so let’s break them down to help you find the correct one.

Option A: Mustn’t

“Mustn’t” is the contraction for “must not,” which conveys prohibition or something that is not allowed. For example:

• You mustn’t smoke here (It is not allowed to smoke).

However, in the sentence, we are not talking about something that is forbidden. Instead, we are referring to something unnecessary, making “mustn’t” the wrong choice here.

Option B: Wouldn’t

“Wouldn’t” suggests that something is conditional, relating to hypothetical situations or past behavior. For example:

• He wouldn’t go to the party if it was raining (Conditional behavior).

In the sentence, “You wouldn’t have bothered coming” could make some sense in informal conversation, but it does not match the context of “I’ve already finished it.” The speaker isn’t talking about a hypothetical situation—they’re stating a fact. Therefore, “wouldn’t” isn’t the best fit here.

Option C: Needn’t

“Needn’t” is the contraction for “need not,” which indicates that something is not necessary. For example:

• You needn’t worry about dinner (It’s unnecessary to worry).

In the context of the sentence, “You needn’t have bothered coming” is perfect. It conveys that it wasn’t necessary for the person to come because the task was already completed. This fits both the tone and meaning of the sentence. Therefore, C. needn’t is the correct answer!

Summary:

The correct option is C. needn’t. This choice accurately reflects the idea that the effort was unnecessary, making it the best fit for the sentence. Keep this structure in mind the next time you see similar questions!
