How do you read a Fahrenheit thermometer?

1. Each short line equals 0.1 of a degree

2. Each short line equals 0.2 of a degree

3. Each long line equals 1 degree

4. Each long line equals 0.5 of a degree

The correct answer is: Each short line equals 0.2 of a degree

A Fahrenheit thermometer is typically marked with both long and short lines. The long lines represent whole numbers, while the short lines represent fractions of a degree. Each short line on a Fahrenheit thermometer is equivalent to 0.2 degrees, making option B the correct answer. Options A, C, and D are incorrect because they do not accurately represent the measurements on a Fahrenheit thermometer. Option A would be more accurate on a Celsius thermometer, as each short line would equal 0.1 of a degree. Option C would be accurate on both a Fahrenheit and Celsius thermometer, but is not the appropriate measurement for this question. Option D would be accurate for a Celsius thermometer, as each long line represents 0.5 degrees.
