Multiple choice

Which of the following pairs is not correct?

  1. a. Seismograph - Earthquakes

  2. b. Anemometer - Speed of the wind

  3. c. Hygrometer - Water vapour content of the atmosphere

  4. d. Lactometer - Specific gravity of liquids
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All three instruments A, B, and C are correctly matched - seismograph measures earthquakes, anemometer measures wind speed, hygrometer measures atmospheric water vapor. Lactometer is specifically designed to measure the specific gravity of milk (not generic liquids), making this the correct answer for 'not correct' if we interpret the question as identifying the least accurate or oversimplified match.
