How do you read a Centigrade thermometer?

1. Each short line equals 0.1 of a degree

2. Each short line equals 0.5 of a degree

3. Each long line equals 1 degree

4. Each long line equals 0.2 of a degree

The correct answer is: Each short line equals 0.1 of a degree

A Centigrade thermometer is a type of thermometer used to measure temperature in degrees Celsius. It usually has short and long lines to indicate the temperature. The long lines represent 1 degree while the short lines represent 0.1 degrees. Therefore, for each set of short lines, there is one long line in between. The other options may seem close, but they do not accurately represent the increments on a Centigrade thermometer. For example, option B suggests that each short line equals 0.5 degrees, which is not true as there are 10 short lines between each long line, making 1 degree. Similarly, option C suggests that each long line equals 1 degree which is already stated to be true, while option D is incorrect as each long line is not equal to 0.2 degrees. Therefore, option A remains the most accurate and correct answer.
