Which of the following is not an effective way to find out about a character? How the stars were positioned when they were born
How they look
How others react to them
How they act?

How the stars were positioned. If you believe in these things I suggest just knowing what their zodiac sign is because it is just the easier way.

How the stars were positioned( meaning zodiac signs) because they are not always accurate. How others react to them may be reflecting on something they have done in the past, how they look could be their choice or a sign of what they have been doing, and how they act is a sufficient way to judge someone. the answer is how the stars were positioned.

Then what do i do after i read the excerpt? i’m not really understanding the question here.
