The diagram shows four thermometers, labeled W, X, Y, and Z. The freezing and boiling points of water are indicated. Rank the thermometers according to the size of a degree on their scales, smallest to largest.

Question

Quizplus · Accepted Answer

Thermometer Z covers the largest range between the freezing and boiling points of water, so its degree must be larger than the others. Then, W and Y have the closest range, but Y is longer, so Y and Z are next. Finally, X has the smallest range, so its degree is the largest. Thus, the ranking from smallest to largest degree is Z, X, W, Y, so the answer is D.
