Suppose a thermometer has marks at every one degree increment and the mercury level on the thermometer is exactly between the 25 and 26 degree Celsius marks.We should properly report the temperature measurement as:
A)25°C
B)26°C
C)25.5°C
D)25.50°C
E)25.55°C

Since the mercury level is exactly halfway between the 25 and 26 degree Celsius marks, we can report the measurement as 25.5°C, which represents the midpoint between the two whole degree marks. Choice A is not precise enough to accurately reflect the measurement, while choices B, D, and E are too precise given the marks on the thermometer.
