Timothy is writing a persuasive essay. He writes a main claim and takes some notes.

Question

Main Claim: Children should begin taking a foreign language in elementary school.

Note 1: Learning a foreign language gets more difficult as a person gets older.

Note 2: Knowing another language is more important than ever because of increasing globalization.

Note 3: There are statistics about how long it takes to become fluent in a language.

Note 4: Research shows that learning a foreign language helps students in other subjects.

Which note should Timothy label as evidence?

Answer 1

3 is referring to statistics, which is evidence (numbers, you know).
4 might be evidence, depending on what "research shows" and how it's presented.
