The answer is B. Metal is a good conductor so the metallic frame of the chair conducts the thermal energy from the sun, causing it to heat up. However, wood is a poor conductor so its temperature will remain more or less the same.

Option C is your answer. The way it's worded, it first wants you to find the difference (meaning subtract) between 5 and 6/7 and then multiply by the 5.
