Ptolemy, an astronomer who lived during the second century ce, created a deeply complex model to describe the motion of the planets, a category he thought included the moon and the sun. he believed that all these celestial objects rotated around earth, which he took to be the center of the universe. this is called a "geocentric model." in the 1400s, copernicus became dissatisfied with the complexity and apparent arbitrariness of ptolemy's model as an explanation of planetary motion. he began to ask what the planetary motions would look like from another vantage point in space, such as the sun. pursuing this hypothesis led copernicus to a system that describes planetary motion as centered around the sun. this is the "heliocentric model," a hypothesis whose implications have been repeatedly tested.

which of the following are accurate descriptions of the development of copernicus's hypothesis?
check all that apply.

a. copernicus's hypothesis was wrong because it had no foundation in established religious beliefs.
b. copernicus's hypothesis was wrong because ptolemy's hypothesis was widely held.
c. copernicus developed his hypothesis in response to ptolemy's hypothesis about planetary rotation, a hypothesis he found unsatisfying.
d. copernicus saw an unsatisfying explanation and formulated a testable way to understand the motion of the planets.
e. copernicus's hypothesis was a tentative explanation for the motion of the planets.

And whereas our provinces in north america, have been frequently ravaged by indian enemies, more especially that of south-carolina, which in the late war, by the neighboring savages, was laid waste with fire and sword and great numbers of english inhabitants, miserably massacred, and our loving subjects who now inhabit them, by reason of the smallness of their numbers, will in case of a new war, be exposed to the late calamities; inasmuch as their whole southern frontier continueth unsettled, and lieth open to the said savages. and whereas we think it highly becoming our crown and royal dignity, to protect all our loving subjects, be they ever so distant from us; to extend our fatherly compassion even to the meanest and most unfortunate of our people, and to relieve the wants of our above mentioned poor subjects; and that it will be highly conducive for accomplishing those ends, that a regular colony of the said poor people be settled and established in the southern territories of carolina."- from  charter of georgia, 1732 based on the passage, it can be determined that the main reason the king of england wishes to establish a new southern colony is becausea)he wants to provide a safe haven for all of his loyal british subject'sb)he wants to protect the fathers of each family in order to keep them safe.c)he wants to make sure there will be enough soldiers in the event of another war.d)he wants to use the new colony to protect the other colonies from attack
