Question

what is the logical conclusion, based upon the information given in the problem below?

on a hot summer day, jen is in a foreign country. she wonders which temperature scale is used there, celsius or fahrenheit. thermometers on two local banks read 30°. since 30° fahrenheit is below freezing, which scale is being used?

a. the celsius scale is being used.

b. it is below freezing.

c. the fahrenheit scale is being used.

d. the thermometers are broken.

Explanation:

On a hot summer day, a temperature of \(30^{\circ}\) Fahrenheit would be below freezing (\(32^{\circ}\) Fahrenheit is the freezing point in Fahrenheit scale). Since it's a hot day, the temperature can't be below freezing. So, it can't be Fahrenheit. Celsius scale is more reasonable as \(30^{\circ}\) Celsius is a warm - hot temperature.

Answer:

A. The Celsius scale is being used.
