Question

Quizplus · Accepted Answer

Thermometer Z has the smallest degree size, because it has the longest length between freezing and boiling points divided into the same number of segments as the other thermometers. Thermometer X has the second smallest degree size, followed by W and Y, which have the largest degree size as they have the shortest length between freezing and boiling points divided into the same number of segments as the other thermometers. Therefore, the thermometers ranked from smallest to largest degree size are Z, X, W, Y. The correct choice is D.
