As for your first question, there are many factors involved in an experiment. It is important to consider any risk factors when designing an experiment. In order to answer this question, think about how you would approach your experiment to reduce those risk factors.
As for your second question, you test your hypothesis as a way to measure the topic of interest. You can do that in many ways, like conducting an experiment to answer your hypothesis, surveying people about the topic of interest, etc.
