Ok Since I anticipate that most people have done their IB SL Biology Paper 2

I have a question.
For the Data Handling Response about food collecting and age, with reference to Menopause.
Can someone clarify to me whether it was a trick or not.
I was under the impression that the less time spent collecting meant the more efficient the women were. As logically one would return when they had collected enough food, on the other hand, the longer one would spend hunting to me would mean the longer it would take them to find food, thus less efficient.
Whereas, most of my peers believed that the longer time spent collecting food meant the more efficient the hunter was, thus supporting the hypothesis.

What are your thoughts??

The menopause hypothesis from feeding thing ??
That was so weird, not only the questions was formulated in a weird way but the hypothesis was not described well enough to make clear conclusions wether is was a true hypothesis or not....

I thought the shortest time taken was the best you were at hunting..
Cause when you are young you are faster .... if you take longer then you feed less and get weaker ...
