Complete the analogy: THERMOMETER is to TEMPERATURE as BAROMETER is to

  • A. altitude
  • B. atmospheric pressure
  • C. humidity
  • D. wind speed

Explanation

Each instrument is paired with the quantity it measures, and a barometer measures atmospheric pressure. Humidity is measured by a hygrometer and wind speed by an anemometer, both of which are offered to test whether the whole family is known. Altitude can be inferred from pressure but is not what the instrument reads.
