Ten years ago, a school with a fixed population decided to increase the size of its student body. The size of the student body t years since the increase began is given as s(t). It is known that the value of the definite integral from 0 to 10 of s'(t) is 400. Which is true? 

• The student body is now at 400.
• The student body is increasing by 400 per year.
• The student body grew by 400 students.
• Nothing can be determined from this information.
