D. because it is a different subject
Answer:
"How do plastic straws impact wildlife?" is the open-ended question.
Explanation:
<em>The other three options can be answered with few definitive answers, but asking how they impact wildlife allows the writer to answer with various responses.</em>
Active voice is when the subject performs the verb. The answer is 'Our puppies played at the cool new dog park' because the puppies are playing, while the rest of the verbs in the other choices are not being acted at by the subject.
