Answer: Gender, nationality, age
Explanation:
If someone is taking another person's perspective he is wanting to understand their point of view and they way of thinking. There are man factors that can influence our perspective and one of them is surely age.
The best example for the age is that we have to consider that the 12 year old boy and 33 year old man don't have the same perspective on things so age can surely influence the person.
Another thing is gender, but not so often. Women are having different perspective on things than men and men have different perspective on things than women.
If we are talking about nationality we must consider religion, beliefs, and culture which are not the same in every nationality so the perspective also can be the same.
