Answer: C.
Explanation:
The Neolithic Period, also called the New Stone Age, is the final stage of cultural evolution or technological development among prehistoric humans. In this stage, humans were no longer dependent on hunting, fishing, and gathering wild plants.
Crystalline silicon (c-Si) dominates wafer-based solar cells. On the other hand, amorphous silicon (a-Si) plays a vital role in thin-film solar cells. Yet, both types of solar cells employ silicon.
Crystalline silicon is the dominant semiconducting fabric used in photovoltaic technology for the manufacturing of solar cells. Those cells are assembled into solar panels as part of a photovoltaic device to generate solar electricity from sunlight. Crystalline silicon (c-Si) cells are received from skinny slices of silicon (wafers) one hundred sixty–240 μm thick, reduce from a single crystal or a block. The kind of crystalline mobile produced depends on the silicon wafer manufacturing procedure. Crystalline silicon solar cells have dominated the photovoltaic market since the very start of the Nineteen Fifties. Silicon is riskless and abundantly available in the earth's crust, and silicon PV modules have proven their long-time period stability over many years of exercise.

Answer:
c. The Mid-Atlantic Gateway connected Savannah and Charleston to Washington, DC via roads and railroads.
Explanation:
The antebellum period was the period of time before the American civil war. This period was characterized by the development of waterways and canals as a means of transportation, linking the east and the west.
Answer:
Lack of jobs and expensive housing
Explanation:
Rural to Urban migration is very influential in most megacities settlements and this will lead to squatter settlements. For example State like Lagos which is Nigeria is one of the most populous State in the world due to its high population, Rural to Urban migration is very common in this part and the more the population the more pressure for the Government to build infrastructure for employment so in that process there will be lack of jobs and even for them to afford normal apartment will be difficult therefore it will lead to squatter settlement for them.
