Directions: Apply the knowledge you have gained from Chapter 3 to select the best answer to the questions about the following reading passage. ​
"Young children unprotected from almost any amount of lead may suffer serious health problems. Lead poisoning can lead to everything from headaches to periods of confusion to learning problems. Inner-city dwellings built before 1960 may contain lead-based paints, the major source of the problem. If the lead paint is peeling, very young children will eat the paint chips. Even the dust from this paint can be harmful. Unfortunately, once someone suffers from lead poisoning, there are no complete cures. The best solutions for families are preventative, such as daily house cleaning and regular washing of hands. Long-term solutions include painting over the old lead paint, but without sanding beforehand. The Mayo Clinic Web site on lead poisoning reminds renters that they have rights protecting their health and safety. Landlords are required by law to find and address sources of lead."
