To manage the grizzly bear population better, the government of Alberta introduced a hunting lottery that awards a limited number of grizzly bear hunting licenses. Predict the year that this regulation was introduced.

The correct answer is - 1990.

Explanation:

From the graph and year - population size table it is clearly understood that the population of grizzly bear is reduced by 39 number from year 1988 to 1989.

But after 1989 from 1990 onwards population of grizzly bear is consistently rising.

Now, let us analyse the data given in question number 2 .

No. of grizzly bear deaths in Alberta from 1976 to 1988 = 581

No. of grizzly bear deaths in Alberta from 1988 to 2000 = 281

From the above data we can clearly say now that the grizzly bear population deaths starts increasing from 1990.

So, the prediction made in question no. 1 that " the government of Alberta introduced the hunting lottery award in 1990 because in 1989 it decreases and then it starts to go up again in 1990",
