allowances tend to spend money on items considered frivolous by their parents whereas
adolescents who receive small weekly allowances do not. Thus, in order to ensure that their
children do not spend money on frivolous items, parents should not give their children large
weekly allowances. Which of the following pieces of information would be most useful in
evaluating the validity of the conclusion above?
b) Any differences among parents in the standard used to judge an item as frivolous
c) The educational background of the child development specialists who made this observation
d) The difference between the average annual income of families in which the parents give their
children large weekly allowances and that of families in which the parents give their children
small weekly allowances

It is B since if parents use the same standard, the argument will hold true.

Conclusion :
Thus, in order to ensure that their children do not spend money on frivolous items, parents should not give their children large weekly allowances.

What would be most useful in evaluating the validity of the conclusion above is to know what is considered frivolous item. An item could be frivolous for one parent but not for another. In that case conclusion may not hold true because large amount itself may vary from $1 to$1000 and more.
