Hello Mr.
I found another different between your answer & the doctor answer
Look at Lecture Five:
It's page 154 in your simplification .
The Q is :
4_ How many children did a Mexican woman have ?
yours: b.7
but he said that the right one is
a.2.5
So !! Wht do ya think ?
Plz focus & give me the right one
I'm still waiting 4 ya:)
