Answer:
A shark is not a mammal.
Explanation:
Mammals are a classification of animals that are famously known for breathing oxygen/air, having fur/hair, mammary glands (which are responsible for the females' ability to produce milk for their young), and (usually) the live birth of their offspring.
Giraffes, dogs, and whales all have the qualities mentioned above. Sharks, however, do not.
Sharks are fish. Unlike the whale, which must go to the surface to breathe the necessary oxygen, sharks have gills. This possession of gills, and not lungs, allows them to breathe only underwater.
Since sharks can't breathe oxygen like mammals can, they are therefore not mammals.
I believe it's C, i'm not sure
One conclusion we can draw from this statement by Pope Gregory III is that C. Christians and non-Christians conducted business with each other in the eighth century.
<h3>How do we know that Christians and Pagans traded in the 8th century?</h3>
"Pagans" is a word used by Christians in the past for people who were non-Christians.
By saying that some Christians sell their enslaved to pagans, Pope Gregory III is proving that some sort of trade existed between the Pagans and Christians which at the very least included slave trade.
