    1. How do lead contamination affect our health? Are you worried about the issue?
    Ans: It will cause different health problems, especially the brain development. I have a little bit worried about the issue.
    2. Do you think there is a best way to carry out a water test? What is it and why do you think it is best?
    Ans: Not really, because the lead particles are very small and you cannot see the lead in every liquid.
