Because
of different religions and culture, schooling was hard to maintain and
establish in United States. National leaders wanted to make education
compulsory to everyone to make good citizens and leadership out of the
children. To make education a primary goal, the Congress sanctioned the Land
Ordinance of 1785 to make education compulsory for everyone, allotting more on
the maintenance on public schools. It is also at this ordinance where religion
and state were separated making religion not a compulsory in their education’s
curriculum.

When exposed to smoke, hydrogen cyanide may play a role in rendering firemen and bystanders incapable of performing self-rescue.
HCN is a toxin that spreads throughout the body; it is hazardous because it inhibits cytochrome oxidase, which stops cells from using oxygen. Loss of awareness, respiratory arrest, and finally death arise from inhibition of the last stage of electron transport in brain cells.
Higher HCN exposures cause cardiovascular collapse, tremors, cardiac arrhythmia (which may not manifest for two to three weeks after the fire exposure), coma, respiratory depression, and respiratory arrest. Inhaling minute concentrations of hydrogen cyanide can result in headaches, weakness, nausea, and vomiting. Larger doses might result in fainting, convulsions, gasping, fast pulse, irregular heartbeat, and even death. In general, the severity of the symptoms increases with the seriousness of the exposure.

Answer:
The species was most likely not found in its natural environment and died because of its inability to adapt to the new environment. Animal species have specific characteristics in their behavior and physical appearance that makes them thrive in a particular climate. Polar bears have white fur, thick coats, and a large structure to support themselves and effectively hunt in the Arctic. When placed in a jungle environment, for example, these characteristics are not useful, and would be a burden to them. This is why when a prehistoric animal if found in a different place, it is because it wandered there (out of need or out of confusion) and couldn't adapt.
