Question

What information is presented as a fact in the article? Check all that apply.

The data cannot be studied in context.

It is difficult to tell if fluoride causes this cancer.

The sources diagnosing the cancer may be unreliable.

Answer 1

Only the first one: "The data cannot be studied in context."

Reason: that sentence is stated absolutely (no hedging), so it reads as a factual claim. The other two are hedged/uncertain language ("It is difficult to tell..." and "may be unreliable") and so are not presented as definite facts. If you want me to check against the actual article, paste the text and I’ll verify.
