Which instrument is described as measuring the closing in a door?

• A. Hygrometer
• B. Pressometer
• C. Monometer
• D. Sphygmomanometer

Answer: (B)

Key idea: measuring the force involved when a door closes is about assessing pressure in the door’s closing mechanism. The instrument described as measuring that closing pressure is the pressometer, because its name signals a device used to gauge pressure within a system, such as the force the door closer exerts as it shuts. Hygrometer is about humidity, which has nothing to do with a door’s closing force. Sphygmomanometer measures blood pressure, a medical context unrelated to doors. A monometer also measures pressure, but in this context the term pressometer specifically aligns with measuring the closing pressure of a door mechanism.
