Question

Fill in the blank with the most appropriate word
“Oh someone ________ in my seat!”
a) Is sitting
b) sits
c) Will sit
d) sit

Answer 1

Hint: The main verb always needs a helping verb (am, is, are, etc.). If the action is going on at the moment, a present continuous tense has to be used. A continuous tense has the suffix -ing attached to it.

Complete answer:
 In the given sentence, it can be understood that the action is ongoing since the person is exclaiming that someone is sitting in his seat at that very moment. Therefore, the correct answer is option a.
Option b is wrong because “sits” is present tense. Using “sits” in the sentence would mean that someone sits in the person’s seat every day. Example: He sits in this red chair to study. This means he sits in that red chair every day.
Option c is wrong because it is in the future tense. The person cannot foresee who will sit in his seat. He can see that someone is already sitting in his seat. Don’t sit on the sofa, grandma and grandpa will sit there.
Option d is wrong because “sit” is present tense. Also, it is used with a plural person. Since it is “someone”, the plural form of “sit” has to be used. The cat sits on the wall. The cats sit on the wall.

Note:
Always take note to see that the option you are selecting has the helping verb included in it since the helping verb isn’t mentioned in the given sentence itself. If there would have been an option with just the word “sitting”, it would have been a wrong answer. The word “sitting” should be accompanied by the word “is”.
