Usin what you learned so far, evaluate the claim: "Rinderpest was a major disturbance to the Serengeti ecosystem"

We have four sentences:
0. Yes, because the wildebeest population grew at the same rate as the buffalo after the disease was eliminated
,1. Yes, because after the disease was introduced, both the number of wildebeest and buffalo decreased a lot.
,2. No, because after the disease was introduced, wildebeest and buffalo stayed the same.
,3. No, because after the disease was introduced, wildebeest and buffalo stayed the same.
Number 3 and 4 are the same and are FALSE because the rinderpest virus eradicated wildebeest. This means that 1 is also FALSE and that 2 is the right answer: Yes, because after the disease was introduced, both the number of wildebeest and buffalo decreased a lot
