Answer:
D. All of the above
Explanation:
Randomized controlled trial is best explained as a study during which people are allocated randomly (by chance alone) to receive one among several clinical interventions. one among these interventions is that the standard of comparison or control. The control could also be a typical practice, a placebo ("sugar pill"), or no intervention in the least . Someone who takes part during a randomized controlled trial (RCT) is named a participant or subject. RCTs seek to live and compare the outcomes after the participants receive the interventions.
In sum, RCTs are quantitative, comparative, controlled experiments during which investigators study two or more interventions during a series of people who receive them in random order. The RCT is one among the only and most powerful tools in clinical research.
That's a simple part of evolution. Humans are built to adapt.
If we go in the frozen tundra, we make coats and other cold-blocking clothes. We find nearby food, like fish. Over time, our differences become more distinct from the rest, and we become less vulnerable to the cold.
