In 1911, a small population of 25 reindeer was introduced on Saint Paul Island. The graph shows the increase in the population of reindeer on the island between 1911 and 1940 with four lines (W, X, Y, and Z) that represent the estimated reindeer population by 1950. If the reindeer population overgrazed their food supply in 1940, which line would likely represent the estimated population of reindeer on the island by 1950?

• W

• X

• Y

• Z
