Although large mammals like elephants and whales tend to live longer than small ones like mice, larger breeds of dogs have shorter life spans, on average, than smaller breeds. A researcher studying the relationship between average body mass and average life span in breeds of dogs concluded that, for every \(2\) kilograms of body mass, life span is 1 month less. According to this conclusion, the average life span of a breed with an average body mass of x kg is y months less than the average life span of a breed with an average body mass of 10 kg!!!!
Select for x and for y values that are jointly consistent with the information provided. Make only two selections, one in each column.

These type of questions are quite regular in focus edition test. The wording tells us that there are various possibilities for x and y, and just one of them is in option.
Only way to do this is by finding the relation between \(x\) and \(y\).
x: Average life body mass
y: Difference in life span
Correct answer: x
"30" y
"10"
