Biology: Final Exam

Students in an advanced biology class, were taking their final exam. The very last question was this:
"Name seven advantages of Mother's Milk.. Worth 70 points or none at all. One student was har pressed to come up with seven advantages. He wrotw:

1) It is the perfect formular for the child.

2) It provides immunity against several diseases.

3) It is always the right temperature.

4) It is inexpensive.

5) It bonds mother and child.

6) It is readily available when needed.

And, then the student was stuck. Finally, in desperation, just before the time was up, he wrote:

He made the only A in the class.
