Explanation

Choice C is correct. It's given that for a $3$ -week period in a town in Illinois, the lowest recorded temperature was $31 degree upper F$ and the highest recorded temperature was $67 degree upper F$ . It follows that the inequality $31 \leq t \leq 67$ is true for any recorded temperature $t$ , in $° F$ , in this town for this $3$ -week period.

Choice A is incorrect and may result from conceptual errors.
