Question

is this sentence in active voice or passive voice? scientists at the large hadron collider, an experimental physics facility, are studying the basic properties of the universe. active voice passive voice

Explanation:

To determine the voice, we analyze the sentence structure. In active voice, the subject (Scientists) performs the action (are studying). The passive voice typically has a form like "is/are + past participle" with the object as the subject. Here, the subject (Scientists) is doing the action of studying, so it's active.

Answer:

A. active voice
