A scientific question is one which can be tested using a set of experiments and comparing with a control variable. Out of the given questions, the nonscientific questions are:
"Why do people in my neighborhood have more cats than dogs?"
"How can the position of the stars and planets be used to predict the future?"
Both of these questions can not be answered through the scientific method, so they are nonscientific.
