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
