The temperature was +21°C at 11 a.m. The temperature rose 4°C by 1 p.m. What was the temperature at 1 p.m.? Rachel thought the answer was +25°C. Is Rachel's answer reasonable? A. Yes, because the temperature started at +21°C and then got 4°C warmer, so the temperature at 1 p.m. will be warmer than +21°C. B. No, because the temperature started at +21°C and then got 4°C cooler, so the temperature at 1 p.m. will be cooler than +21°C.
