Answer 1

Answer:

a Mary,Rosy,and Peter is the answer 101 %

Answer 2

Answer:

d) Mary, Rosy, Steve

Explanation:

Let’s approach this from the details given in the question.

Jack is one member of the team.

So, other members will consist of 1 male and 2 females.

Out of the male members that we are given (Peter, Jack, Martin, Steve) —  

Peter and Jack do not work together, so - our choices for the male member are between Martin and Steve.

Let us eliminate option (a) and option (c) because they have Peter.

We know that Martin and Stephanie cannot work together.

So we eliminate option (b), which contains them both.

So, the only option remaining is our correct answer - Mary, Rosy and Steve = Option (d).
