This question seems to be incomplete. However, there´s enough information to find the right answer.
Answer:
In the article "Inquiring Reporter," by Claire Kifferstein from Girls High Record, the claim is the question about the Regents' examinations being valuable or not.
Explanation:
A claim is a statement of opinion, which is supported by evidence in the form of claims and counterclaims. The main claim appears in the first paragraph of the article. The rest of the text provides evidence that supports the claim that Regents are valuable, under the subtitle "Pro", as well as evidence for the claim that they’re not, in the section "Cons."
