Final answer:
Transforming the passive sentence 'The evaluation was performed by us' into active voice provides 'We performed the evaluation.' The active voice is more assertive and direct, highlighting the subject as the one performing the action.
Step-by-step explanation:
The sentence 'The evaluation was performed by us' is in passive voice, where the subject receives the action. In the active voice, the subject performs the action of the verb. Therefore, converting this sentence into active voice would result in 'We performed the evaluation' which is more forceful and direct.
Here's why: In the active voice, 'we' are the ones taking action, instead of the action happening to us. This is similar to the difference in the example provided - 'A survey of 300 students was conducted at a large state university in the southern United States.' (passive) vs 'We conducted a survey of 300 students at a large state university in the southern United States.' (active). The active voice emphasizes the doer of the action, making your sentence more straightforward and assertive.
