CorrectNot quiteAnswer B

Correct answer: B

Explanation

  1. Before the new reading, the highest was 18+12=3018 + 12 = 30 °C.

  2. 33 °C is now the highest and 18 °C is still the lowest.

  3. New range = 33−18=1533 - 18 = 15 °C.

Worth noting

21 °C subtracts the old range from the new reading. 45 °C adds 33 to the old range, and 12 °C ignores the new highest value.
