Final answer:
The correct answer is option (d). The coldest city based on the given temperatures is Calgary with -15 degrees Fahrenheit.
Step-by-step explanation:
To determine which city is the coldest based on the given temperatures, we can compare the absolute values of the temperatures provided for each city. The absolute value is used to disregard the negative sign and focus on the magnitude of the temperature.
a) Banger: -3 degrees Fahrenheit
Absolute value: 3
b) Fairbanks: -12 degrees Fahrenheit
Absolute value: 12
c) Fargo: -8 degrees Fahrenheit
Absolute value: 8
d) Calgary: -15 degrees Fahrenheit
Absolute value: 15
Comparing the absolute values, we see that Calgary has the highest absolute temperature, making it the coldest among the given cities. The negative sign only indicates the direction of temperature below freezing, not the magnitude of coldness. Therefore, based on the provided temperatures, Calgary at -15 degrees Fahrenheit is the coldest city.
It's important to note that this comparison assumes the temperatures are representative of the current conditions and that no extreme local variations exist within each city. Additionally, weather conditions can change rapidly, so real-time data is crucial for accurate assessments.
