Answer:

3

Step-by-step explanation:

The given data shows that only 1 row was in use. We also know that Mr. Torres is an adult. So for the ease, lets use A for Adult and S for student.

The seating must fulfill the requirements that 4 students must be between adults such that it would be "A-S-S-S-S-A"

On a row of 11 seats, this should be the searing arrangements.

A-S-S-S-S-A-S-S-S-S-A ( for 1 row).

Mr. Torres could be any A .
