During an ice age, the average annual global temperature was at least 4 degrees Celsius lower than the modern average. If the average annual temperature of an ice age is y degrees Celsius and the modern average annual temperature is x degrees Celsius, which of the following must be true?
- y = x - 4
- y
x + 4 
x + 4The correct answer is:
Since, the average annual global temperature was at least 4 degrees lower than the median average y ≤ x – 4.
