Complete the sentence with the most suitable option:
We won't go unless the weather ________ fine.
The sentence refers to a future event on a designated date as a part of plan or arrangement. In such cases, simple present tense form or base form of verb is used. Thus, "is" in option B is the correct answer. This is the third person present singular form of the verb 'be' and is used to indicate the simple present tense. "Will be" in option A is incorrect as this indicates the simple future tense or an event that hasn't taken place as yet. "Won't be" in option C is incorrect as it is the negative contraction for an event in the future. "Isn't" in option D is incorrect as it will make the sentence a double negative. "We won't go" is already a negative and "weather isn't fine" becomes double negative. This is ungrammatical and incorrect. Thus, option B is the correct answer. |
