They claimed that African Americans had the right to vote but not to hold office. They claimed that African Americans were US citizens but not citizens of Georgia.
First, there were two independent clinical psychologists who were present or on call 24 hours a day. They had the power to intervene and to remove anyone from the study if they thought they were in distress.
Second, we had paramedics and security guards on hand and ready to intervene at a moment’s notice if anything untoward happened in the study.
Third, the study was constantly monitored by members of a five-person independent ethics panel. This was chaired by a Member of Parliament and also included members of the Holocaust Educational Trust, the Howard League for Penal Reform, the BBC’s Independent Editorial Policy Unit and a senior academic psychologist. This committee had the power to change the way the study as a whole was run and to terminate it if they had ethical concerns.

Answer:
Caverns are created when moving groundwater mechanically weathers sediment and transports it elsewhere, leaving behind large empty spaces.
Explanation:
The movement of groundwater causes erosion that is responsible for the formation of caves. These caves are formed due to mechanical weathering of rocks. Mechanical weathering plays an major role in creating caverns by dissolving of limestone rock due to acidic water that reacts with limestone and removes it with the passage of time that forms caves. The normal pH water can't perform this job due to no reaction occurs with limestone.
The sun hits bodies of water (ponds, oceans, pools, puddles) and it evaporates into a gas known as water vapor which goes up and forms a cloud. When the cloud gets heavy the water condensates back into little droplets and falls back to the ground. This is rain.
