In the 1800s, an important motivation for both “old” and “new” immigrants to settle in ethnic neighborhoods was

a. religious freedom.
b. proximity to schools.
c. a common language.
d. a chance to assimilate.

C. a common language.

Explanation:

As the settlers had different nationalities, with different languages, not all spoke English. In this way it was difficult for them to communicate between individuals who had different languages and cultures and for this reason ethnic neighborhoods emerged.

In these neighborhoods people who spoke the same language could communicate with one another, in addition, the ethnic neighborhoods maintained the culture and the traditions of their country of origin.

isaac newton first proposed that earth was not perfectly round. instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator.

the idea of the earth being a flat disc is also inconsistent with the fact that a given lunar eclipse is only visible from half of the earth at a time. the only shape that casts a round shadow no matter which direction it is pointed is a sphere, and the ancient greeks deduced that this must mean the earth is spherical.
