There is no way to know whether you got this right because this is not an objective question. There is no official right answer for this. Different people have different opinions about what we need to know.
For example, some people would say that we don't need to know about a candidate's sex life, their religion, or their finances. But other people argue that these things are very important in judging whether the candidate would make a good leader because they show moral character or the ability to relate to "regular" people.
Just about everyone agrees that we need to know the candidate's stances on issues. Most people would agree that we need to know what the candidate has done for a living in the past. Most people would also argue that we should know if the candidate has a criminal record.
However, there is no objective answer. Different people want to know different things about candidates.
