B. A 300-pound supervisor
C. A bushel of potatoes in a produce warehouse
D. A workplace temperature of 40 degrees Fahrenheit

3. The greater the match between worker capabilities and task demands:

A. The greater the chance of worker injury/illness
B. The lower the chance of worker injury/illness
C. Has no impact on chance of worker injury/illness
