Tolerance can also be described as something that varies between different people depending on health status. Which option reflects that definition?

• A. The amount of food consumed at a single sitting.
• B. The ability to withstand pesticide exposure and not be injured.
• C. Something that varies between different people, depending on health status.
• D. A pesticide remaining immediately after an application.

Answer: (C)

Tolerance describes how much pesticide exposure a person can handle without harm, and this can vary from person to person based on health status. Health factors like illness, age, liver or kidney function, and concurrent medications influence how a chemical is processed and tolerated. The option that matches this idea says that tolerance is something that varies between different people, depending on health status, which directly reflects that variability. The other options describe related ideas that don’t capture the variability across individuals: one is about how much is eaten at once (unrelated), another states the general ability to withstand exposure without noting differences among people, and the last is about pesticide residue after application.
