Which condition describes a pedal force up to 70 pounds?

• A. 50 pounds
• B. 60 pounds
• C. 70 pounds
• D. 80 pounds

Answer: (C)

Understanding pedal force categories often uses an upper bound to describe the range. When a condition is described as “pedal force up to 70 pounds,” it means the force required does not exceed 70 pounds, with 70 pounds serving as the threshold. Among the given values, the one that matches that upper limit is seventy pounds, since it represents the boundary described by the phrase. Values of fifty or sixty pounds describe smaller upper bounds (up to 50 or up to 60), which don’t fit the stated limit, and eighty pounds exceeds the limit. So seventy pounds is the best match for the described condition.
