Hello there,
I've never seen the video before, But I will give my best guess on this matter. I believe that your correct answer may be "<span>a visual that demonstrates how some bacteria may survive antibiotic treatment". This would be my best guess.
Hope this helps.

The answer would be A, helped. A transitive verb is an action verb, which is a verb where someone does something physically or mentally, with an indirect object right after, or someone who receives the action of the verb. So, the action verb in the sentence is helped and the indirect object is the injured man, which makes the transitive verb "helped." Hope this helps!
