had worked
will work
is going to work
had been working E. will have been working
Answer is Right!
Answer is Wrong!
The correct answer is: E. will have been working.
The sentence is in the future perfect continuous tense. This tense is used to talk about an action that will have been happening for a period of time by a specific point in the future. In this case, the specific point in the future is the end of this month. The action is “working as one of the assistants of Bill Gates.”
The other options are incorrect because they do not express the idea that the action will have been happening for a period of time by the end of this month.
- Option A, “had worked,” is in the past perfect tense. This tense is used to talk about an action that was completed before a specific point in the past. In this case, the specific point in the past is the end of this month. However, the sentence is about an action that will be happening, not an action that was completed.
- Option B, “will work,” is in the simple future tense. This tense is used to talk about an action that will happen at a specific point in the future. In this case, the specific point in the future is the end of this month. However, the sentence is about an action that will have been happening for a period of time by the end of this month.
- Option C, “is going to work,” is in the future progressive tense. This tense is used to talk about an action that will be happening at a specific point in the future. In this case, the specific point in the future is the end of this month. However, the sentence is about an action that will have been happening for a period of time by the end of this month.
- Option D, “had been working,” is in the past perfect progressive tense. This tense is used to talk about an action that was happening for a period of time before a specific point in the past. In this case, the specific point in the past is the end of this month. However, the sentence is about an action that will be happening, not an action that was happening.
