Answer 1

The correct way to change the passive sentence to active voice is 'NASA has scheduled seventy-five spacewalks to put the station together.'

Step-by-step explanation:

To change a verb from passive to active voice, you need to make the subject of the sentence perform the action rather than receive it. The sentence in question is 'Seventy-five spacewalks to put the station together have been scheduled by NASA.' When converted to active voice, it becomes 'NASA has scheduled seventy-five spacewalks to put the station together.'

Therefore, the correct answer is (a) NASA has scheduled seventy-five spacewalks to put the station together.
