Answer: active voice
Step-by-step explanation:
The sentence "NASA has identified a potentially dangerous asteroid" is in active voice. In active voice, the subject of the sentence performs the action.
Here's a breakdown of the sentence:
- Subject: NASA
- Verb: has identified
- Object: a potentially dangerous asteroid
In this sentence, NASA (the subject) is performing the action of identifying (the verb) a potentially dangerous asteroid (the object). This sentence is structured in a way that clearly shows the subject performing the action, making it an example of active voice.
In passive voice, the subject receives the action rather than performing it. An example of the same sentence in passive voice would be: "A potentially dangerous asteroid has been identified by NASA." In this case, the subject "a potentially dangerous asteroid" is receiving the action "has been identified" by NASA.
I hope this helps!
