Can you help me with this?

Would (A) or (D)be the best answer?

A teacher would be wise to study other
cultures and their beliefs since:

A. Understanding cultural differences
allows a teacher insight into the
family's expectations of the
children.

B. parents will be impressed with
the teacher's knowledge.

C. children do not share family
interests with their teacher.

D. multi-culturalism is part of
a balanced curriculum.

Although both A and D are true, A is the best answer. Multi-culturalism has little place in subjects such as science and math.
