For five years, the amount of damage to trees caused by black diamond owls in Redfern National Park rose by ten percent or more annually. In order to curb these worrisome increases, park officials sprayed trees with a chemical preventing the owls from reproducing. Even though the number of black diamond owls in the park decreased, the amount of damage to trees caused by black diamond owls continued to increase significantly for the next two years.
Which of the following, if true, most helps to explain why the park officials' action did not achieve its goal?
A. Black diamond owls less than 3 years old do not cause as much damage to trees as do black diamond owls who are between the ages of 3 and 20 years (their average lifespan).
B. A small percentage of trees in Redfern National Park are harvested for lumber and replanted each year.
C. Black diamond owls are capable of reproducing at a rate greater than that of most other birds.
D. In addition to spraying trees, park officials placed nets designed to capture black diamond owls.
E. The smaller number of owls in Redfern National Park made the park a more desirable destination for vacationers.

Why did the amount of damage to trees caused by black diamond owls continued to increase significantly for the next two years, even though the number of black diamond owls in the park decreased(the owls died with no new births)?
Ideas:
Black diamond owls release some chemical which stays behind and continues to cause damage to the trees
There was some other set of Black diamond owls which caused the trees harm - some visitors probably
A. Black diamond owls less than 3 years old do not cause as much damage to trees as do black diamond owls who are between the ages of 3 and 20 years (their average lifespan).
This makes sense, the less than 3 year old which were not causing any harm so far, started damaging the trees.
B. A small percentage of trees in Redfern National Park are harvested for lumber and replanted each year.
This is irrelevant. This doesn't help understand why the damage to trees caused by black diamond owls increased
C. Black diamond owls are capable of reproducing at a rate greater than that of most other birds.
This is irrelevant. We are not concerned with the rate at which black diamond owls reproduce.
D. In addition to spraying trees, park officials placed nets designed to capture black diamond owls.
This should increase the belief in the expected outcome that the damage should have reduced. Goes in opposite direction
E. The smaller number of owls in Redfern National Park made the park a more desirable destination for vacationers.
That's great but this is still irrelevant. This doesn't help understand why the damage to trees caused by black diamond owls increased

A. Black diamond owls less than 3 years old do not cause as much damage to trees as do black diamond owls who are between the ages of 3 and 20 years (their average lifespan). Suitable This explains that even if new off-springs had been curbed, the major damage was anyway being done by more mature owls.
B. A small percentage of trees in Redfern National Park are harvested for lumber and replanted each year. Eliminated Out of context. If being harvested, then park officials would have known about it or at least not attribute such damage to owls.
C. Black diamond owls are capable of reproducing at a rate greater than that of most other birds. Eliminated This does not help explain the conflict. The reproduction rate has not been compared with the effects of the chemical, rather only other species.
D. In addition to spraying trees, park officials placed nets designed to capture black diamond owls. Eliminated Provides no additional fact, to resolve the conflict
