Question

1. which statements about secondhand smoke are true? select all that apply. it affects primarily infants and children under the age of five years. it can have serious health consequences for both children and adults. it is harmless to most healthy people of all ages. it is smoke exhaled by smokers.

Explanation:

• Secondhand smoke is not limited to affecting only infants and children under five. It impacts people of all ages. So the first statement is false.
• Secondhand smoke contains many harmful chemicals. It can cause various health problems like respiratory issues, heart - related problems etc. in both children (e.g., more frequent ear infections, asthma exacerbations) and adults (e.g., increased risk of heart disease, lung cancer). So the second statement is true.
• As mentioned above, secondhand smoke is not harmless. It has been linked to numerous health risks. So the third statement is false.
• Secondhand smoke is indeed the smoke exhaled by smokers (mainstream smoke) along with the smoke from the burning end of a cigarette (sidestream smoke). So the fourth statement is true.

Answer:

B. It can have serious health consequences for both children and adults.
D. It is smoke exhaled by smokers.
