I have a question its which diagram correctly represents this sentence? Sara, José, and Kenny were studying together for the test.

How can I post a link to show you the diagrams?

If you copy the question and paste it into google and click the first link its open study someone posted the picture of the diagram and the same question.

Ok I think I got it its A right?

It is just a picture of the diagram not a website.

Use the different sections to find the exact structure you're looking for.

For example, take a look at how compound subjects are done here:

For your sentence, you'd need to add a third subject, but you'd keep the conjunction like in this example.

Ok is there a way for me to post a picture of the diagrams?

No, sorry.

If it's on a website, though, and you can tell me how to find that website and the particular webpage, I might be able to find it.

B and D are obviously wrong because of how the verb is treated.

Between A and C, which is obviously correct?

I am do not know which is obviously correct. Can you please tell me. I just missed the question and I had to redo the test already so many times. And I am on the question right now. I already missed one wrong. I'm guessing its A?

In the original sentence, is the verb "were studying" or "studying were"?

??

Please I am on the last question If I get it right I pass!
