Janet's Assertion:
Janet argues that the aurochs' extinction was likely due to rinderpest, a disease introduced via domesticated cattle from Asia, rather than hunting or habitat displacement.
Junko's Disbelief:
Junko is skeptical and asks for more evidence to support Janet's argument.
Let's analyze the options:
A. The aurochs in Eastern Europe went extinct during a time period wherein trade between Asia and Eastern Europe was weaker than it had been during earlier periods wherein they thrived.
This option weakens Janet's argument because it suggests that the trade (and thus the potential introduction of rinderpest) was less likely during the period of the aurochs' extinction.
B. Most historians agree that Asian domesticated cattle were first imported to Eastern Europe in the late 1600s.
This option weakens Janet's argument because it implies that Asian cattle (and thus rinderpest) were not present in Eastern Europe until after the aurochs went extinct in the early 1600s.
C. Roughly half a dozen other species of cattle went extinct alongside the aurochs.
This option could support Janet's argument, as it suggests a widespread event (like a disease) that affected multiple species, not just the aurochs.
D. Records from that era show that aurochs were very hard to hunt.
This option strengthens Janet's argument by supporting the idea that hunting was not a significant factor in the aurochs' extinction.
E. Several wild animals larger than the aurochs also went extinct during the 1600s.
This option could indirectly support Janet's argument by suggesting a widespread environmental or ecological factor that affected large animals, potentially including a disease like rinderpest.
Conclusion:
Best statement to strengthen Janet's assertion:
D.
Best statement to strengthen Junko's disbelief:
B.
