What does infrastructure refer to? process by which a nation improves the economic, political, and social well-being of its people type of economy that is based on heavy manufacturing services and facilities necessary for an economy to function level of farming in which a person raises only enough food to feed his or her family

None of the above

Explanation:

The second option, "type of economy that is based on heavy manufacturing services and facilities necessary for an economy to function", comes close to the answer but is wrong where it says, "type of economy that is based on heavy manufacturing services...".

Infrastructure is the fundamental facilities(not "heavy" manufacturing services) and systems that serve a country, city, or specified area or group of people in that area which includes the services and facilities necessary for its economy to function. They are "essential" physical components that are basic for a society to function. It comprises such things as: roads, railways, bridges, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband speeds).

the 14th amendment establishes that the law protects all citizens equally.

in this case the passage of the 14th amendment   that was violated was the last part in which it states that there is equal protection of the law.
