It is Sultan of Turkey I am looking at my old school packet right now.
I believe the answer is: Explain
Explain is the act of figuring out how things turn out as it is. In scientific field, to obtain proper explanations, researchers need to construct a hypothesis and tested them with proper scientific method in order to find relevant facts that might connected to the occurrence.
Answer:
B. Guides
Explanation:
The park ranger is a singular subject, so instead of saying "park ranger" replace it with he or she, then add the words to see if they sound correct.
He/she guide the tourists doesn't sound quite right. It would sound better if the subject was plural. <em>Ex: </em><em><u>The rangers guide the tourists</u></em><em>...</em>So this eliminates answer A.
He/she guides the tourists sounds grammatically correct because it is.
Nah i'm just kidding. It sounds correct because the subject is singular. When you have a singular subject, the present tense verb must be plural. <em>Ex: He walks....It climbs....Lilah runs.</em> The rule applies to all of them.
P.S. Don't forget that the verb always applies to the subject in front of it, not behind it. So don't pit the words "guide/guides" with "the tourists" because you might get it wrong.
