Read the claim and reason. claim: our school cafeteria should offer more meatless main dishes. reason: there are a significant number of vegetarians attending our school. what evidence best supports the student’s reason? the results of a student survey suggest that twenty-three percent of the students consider themselves vegetarians. though school food is funded by state and county governments, the menu is determined by school cafeteria staff. salads and meatless pasta dishes add variety to school menus and provide vegetarians with possible choices. vegetarians rely on beans, nuts, and greek yogurt as alternate sources of protein in their diets

The correct answer is A. The results of a student survey suggest that twenty-three percent of the students consider themselves vegetarians.

Explanation:

The word "evidence" refers to information such as examples, statistics, quotations, etc. that directly proved and explain a claim or reason. This implies in the case of evidence for the reason "There are a significant number of vegetarians attending our school" the evidence should show the percentage or number of vegetarians and this should be relevant to support the main claim of including meatless dishes. Considering this, the most appropriate evidence is "The results of a student survey suggest that twenty-three percent of the students consider themselves vegetarians" because this directly proves the number of percentage of vegetarians is significant which is the main point of the reason.
