Fill in the blanks with suitable active and passive verb forms.I _____...
The correct answer is option A: "Have been working."
Explanation:
To determine the correct verb form, we need to consider the tense and subject of the sentence.
1. Tense: The sentence does not provide any specific timeframe, so we should use the present perfect continuous tense. This tense is used to describe an action that started in the past, is still ongoing, and may continue into the future.
2. Subject: The sentence does not provide any specific subject, so we can assume that it refers to the first person singular "I."
Now, let's analyze each option:
A: Have been working - This is the correct form. It matches the present perfect continuous tense and the subject "I."
B: Has been working - This form is incorrect because "has" is used with the third person singular subject, not "I."
C: Was working - This form is incorrect because it uses the past continuous tense, which does not convey the ongoing nature of the action.
D: Am working - This form is incorrect because it uses the present continuous tense, which does not convey the duration of five hours.
In conclusion, the correct answer is option A: "Have been working." This form matches the present perfect continuous tense and the subject "I."

Understanding the Correct Answer
The sentence "I _______ for five hours" requires a verb form that correctly expresses an action that has been ongoing and is still relevant to the present. The correct answer is option 'A': "Have been working."
Why 'Have been working'?
- Present Perfect Continuous Tense:
- "Have been working" is in the present perfect continuous tense. This tense is used to indicate that an action started in the past and has continued up to the present moment.
- Duration Indication:
- The phrase "for five hours" suggests that the action of working began in the past and is still continuing, which aligns perfectly with the present perfect continuous form.
Analysis of Other Options
- Option B: 'Has been working'
- This form is incorrect because "has" is used with singular subjects (he, she, it). The subject "I" requires "have."
- Option C: 'Was working'
- This option is in the past continuous tense, which indicates an action that was ongoing in the past but does not connect it to the present.
- Option D: 'Am working'
- This form is present continuous but does not convey the duration of five hours, making it inappropriate for this context.
Conclusion
In summary, the best choice is "Have been working" because it accurately reflects the ongoing nature of the action linked to the present, satisfying the grammatical requirements of the sentence.
