While human migrations historically have led to a giant reduction in the number of animals used as food by humans such as deer and cat or animals that attack humans, during times of need humans likely also killed large herbivores such as the Woolly Mammoth for food. The large reduction in the population of European Woolly Mammoth during 8000 BC, a period of recorded famine in Europe, is evidence of such activity.

Which of the following if true strengthens the viewpoint that the reduction in the population of European Woolly Mammoth was caused by the hunting by humans?

A. The population of the giant hippopotamus, another large herbivore also declined during the same period.
B. The number of fig trees, European Woolly Mammoth's primary food source, significantly increased after the decline of the herbivore.
C. The population of large Cape Lion, European Woolly Mammoth's primary predator, also decreased during 8000 BC.
D. The few European Woolly Mammoths that survived the famine of 8000 BC lived in high altitudes rarely habituated by humans.
E. Deer population in Europe during the famine of 8000 BC declined tremendously because of lack of food.

A. The population of the giant hippopotamus, another large herbivore also declined during the same period.- How this is related to decline in population of EWM?- Out of Scope
B. The number of fig trees, European Woolly Mammoth's primary food source, significantly increased after the decline of the herbivore.- Again this doesn't explain humans killed EWM. OOS
C. The population of large Cape Lion, European Woolly Mammoth's primary predator, also decreased during 8000 BC-Still Human connection missing.
D. The few European Woolly Mammoths that survived the famine of 8000 BC lived in high altitudes rarely habituated by humans.-[color=#00a651]Yes, that's it So few people living in this area=EWM survived.- Answer[/color]
E. Deer population in Europe during the famine of 8000 BC declined tremendously because of lack of food.- Deer population decline has nothing to do with Decline in EWm because of Human hunting- OOS

E. Deer population in Europe during the famine of 8000 BC declined tremendously because of lack of food.


Conclusion- During 8000 BC, large reduction in the population of WM is because of human hunting for food.
Premise- General info- human migration leads to giant reduction in number of animals used as food.
WM is used as food by humans.
A- out of scope, does not give any info about WM.
B- Yes it tells WM is reduced but reason is human not clear.-Out
C- Predator of WM is decreased- doesn't connect humans with WM- Out
D- Okay the survived WM is the ones who didn't lived near human settlement- make sense if the survived one are the ones lived away from human settlements then the reason they survived is not killed by humans.
E - Talk about deer -straight out

Answer is D

If cause is removed thn effect is also removed will clearly be the strengthner
D clearly fits
