Question

exposure to secondhand smoke can cause or increase the risk of developing
multiple choice
high altitude sickness and sleep apnea
multiple sclerosis and vasculitis
pneumonia and tuberculosis
heart disease and lung disease

Explanation:

Secondhand smoke contains harmful chemicals. It can damage blood vessels and the heart (increasing heart - disease risk) and irritate and damage the lungs (increasing lung - disease risk). High - altitude sickness is due to low oxygen at high altitudes, not secondhand smoke. Multiple sclerosis and vasculitis have complex causes (autoimmune, genetic, etc., not mainly secondhand smoke). Pneumonia can be caused by infections (bacteria, viruses), and tuberculosis is caused by the Mycobacterium tuberculosis bacteria. While secondhand smoke can somewhat affect the immune system, it is not the main cause for pneumonia and tuberculosis in the context of this question compared to its well - established link with heart and lung diseases.

Answer:

heart disease and lung disease
