Question

based on information in the passage, which sentence best describes the relationship between houseplants and people’s health?
a houseplants can worsen people’s health by requiring complicated care.
b houseplants can worsen people’s health by changing the air quality inside homes.
c houseplants can improve people’s health by making people want to go outside and get more exercise.
d houseplants can improve people’s health by decreasing people’s stress and improving the environment.

Explanation:

To determine the correct answer, we analyze each option:

• Option a: Houseplants' care complexity is not typically linked to worsening health in a direct health - impact way related to standard health - plant relationships.
• Option b: Generally, houseplants improve air quality (e.g., by filtering toxins, producing oxygen) rather than worsening it, so this is incorrect.
• Option c: Houseplants don't primarily make people want to go outside for exercise; their health benefits are more direct like stress reduction or air purification.
• Option d: Houseplants are known to reduce stress (through their aesthetic and calming presence) and improve the environment (e.g., air quality, humidity), which in turn improves people's health. This aligns with scientific knowledge about the health benefits of houseplants.

Answer:

d. Houseplants can improve people's health by decreasing people's stress and improving the environment.
