A. true b. false: john gray's "venus/mars" approach to gender differences is widely accepted among communication scholars.

The statement is  "False".

John Gray who was an American author wrote a book “Men Are from Mars, Women Are from Venus”. The book expresses that most regular relationship issues among people are a consequence of mental contrasts between the genders, which the writer embodies by methods for its eponymous representation: that people are from particular planets, men from Mars and ladies from Venus, and that each sex is accustomed to its own particular planet's traditions, however not to those of the other. And this approach was not accepted by communication scholars. 

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
