Explanation:

A representative sample should be unbiased and randomly selected from the entire population (students at the local middle - school). Asking students at a pizzeria, cafeteria, or mall food court is likely to over - represent students who visit those places and may have a preference for certain types of food. Asking from the student directory is a more random way to sample the entire student population.

Answer:

ask every tenth student who enters a pizzeria on Thursday, ask every tenth student who enters the cafeteria on Tuesday, ask every tenth student who enters the food court at the mall
