The study reported, "Girls aged 5-15 in villages that received the recruiting services were 3 to 5 percentage points more likely to be in school and experienced an increase in Body Mass Index, reflecting greater nutrition and/or medical care. However, there was no net gain in height. For boys, there was no change in any of these measures." Why do you think the author points out the lack of change in the boys?

Step-by-step explanation:

From the given information:

The study group includes Girls and Boys

So; we can have a table

Groups        Treatment ( Recruiting services)            Points

Girls              likely to be in School  and increase        3-5 %

                    in Body Mass Index, reflecting greater

                    nutrition and/or medical care.                    

                    Net gain in height                                         -

Boys            likely to be in School  and increase        No changes

                    in Body Mass Index, reflecting greater

                    nutrition and/or medical care.                    

                    Net gain in height                                      No changes

Why do you think the author points out the lack of change in the boys?

From the information above; we need to understand that the point the  author is trying to express is that the  Recruiting services Treatment are largely beneficial for the females rather than the males.

here the number -5 is all of the following except a rational number.
