Very strongly supported. A few pythons recently hatched in North America have the liver disease. Since all pythons die within six months of contracting the disease, these pythons will die within six months. They might appear fine because the disease is hard to detect.

Unsupported. Just because a greater proportion of African-hatched pythons have the disease doesn’t necessarily mean that they’re more susceptible to it. It’s possible that the disease is just more prevalent in Africa.

Unsupported. All pythons die within six months of contracting the disease. It’s possible that some pythons could contract the disease later in life. They’d still die within six months, but they wouldn’t die by the age of six months.

Unsupported. Many pythons hatched in Africa have the disease, but we don’t know whether many of the inexpensive pythons from the shipment have it. They might be cheap just because they’re more available, not because they have the disease.

Unsupported. Some pythons hatched in Africa and in North America have the liver disease. But this doesn’t mean that pythons hatched elsewhere do not have it. The stimulus doesn’t mention pythons hatched anywhere else.
