input = day 14; output = 72°F temperature; statement = on day 14, the temperature is 72°F

input = 14°F; output = day 72; statement = 14°F occurs on day 72

input = day 14; output = 72°F/day temperature change; statement = temperature rises 72°F per day

input = day 72; output = 14°F temperature; statement = on day 72, the temperature is 14°F
