Self-study
Two months ago a major shipment of pythons arrived from Africa, resulting in a great number of inexpensive pythons in pet stores. ██████ ██████████ ██ ██████ █ ███████ ████████ ██████ ███████ ████ ███████ ███████ ██ ██████ ███ █████████ ████ █ ██████ █████ ████████ ████████ █ ███ ███████ ████████ ███████ ██ █████ ███████ ████ ████ ████████ █ ████ ███████ ██████████ ██ ███████████████ ███████ ████ ███ ███ ███████ ██ █████████ ██ ██████ ██ ███ █████ ███████ ███ ███ ███████ ███ ██████ ███ ██████ ██ ███████████ ███ ████████
Summary
Many pythons hatched in Africa have a deadly liver disease.
A few recently hatched North American pythons also have the disease.
The disease is hard to detect.
All pythons die within six months of getting the disease.
There are a lot of cheap pythons in pet stores since a big shipment of pythons arrived from Africa.
People interested in buying pythons should beware.
Very Strongly Supported Conclusions
A few recently hatched North American pythons will die within six months.
Many pythons hatched in Africa will die within six months.

Which one of the following ██████████ ███ ██ ████████ ████████ ████ ███ ██████████ ██████
a
Some pythons hatched ██ █████ ███████ ███ ██████ ████ ███ ████ ███ ██████ ███ ██████ ██ █ ██████ ██ ███ █████ ████████
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.
b
Pythons that hatch ██ ██████ ███ ████ ███████████ ██ ███ █████ ███████ ████ ███ ███████ ████ █████ ██ █████ ████████
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.
c
Any python that ███ ███ ████ ██ ███ ███ ██ ███ ██████ ████ ███ ████ ███ █████ ████████
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.
d
The pythons are █████████████ ██████ ███████ ████ ██ ████ ██████ ████ ███ █████ ████████
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.
e
Pythons hatched in ███████ ██████ ███ █████ ███████ ███ ███ █████████ ████ ███ █████ ████████
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.
