Since the beginning of time, some people have believed that the earth is flat. beginning around 300 b. c., however, some began to wonder if the earth is actually spherical in shape.
those that favored the flat earth theory made the following observations:
the earth is stable because it is a flat landmass sandwiched between a flat layer of air and a flat layer of water.
if the earth is spherical, then oceans should be curved on top, but they aren't.
some rivers flow for hundreds of miles but only fall a few feet. the rivers should fall farther if the earth is spherical.
if the earth is spherical, people and animals that inhabit the earth would notice as they walked along its surface.
since mariners are able to use flat compasses to navigate their ships without crashing, the earth must not be a sphere.
those that disputed the flat earth theory countered the claim by observing that christopher columbus was able to sail around the earth without falling off the edge and later, by presenting satellite imagery taken from space of a spherical earth.
this example demonstrates that
a .scientific knowledge is unattainable.
b .it is easy to resolve a scientific argument.
c. argumentation is a necessary part of scientific inquiry.
d. it is not possible to settle a dispute.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
