<span>King stated this, he believed that black people were located at the bottom of the economic ladder. Their two circles of segregation were one that kept them prisoner based on their skin color while the other held them prisoner in poverty and deprivation. The average black person struggles to escape his circumstances but is hindered by these factors. He receives no normal education and no normal social or economic opportunities. When he attempts to try to better himself, he is told to lift himself up on his own by bis bootstraps, advice that is senseless considering he is often barefoot.</span>
The animals used in an experiment that involves USDA pain category B, C, and D activities performed on the same animal should be categorized to USDA category D.
The USDA pain categories are used to categorize the level of pain an animal used in testing and research will be exposed to. The categories are as follows:
- USDA B: the animal will not feel pain of any kind
- USDA C: the animal will feel the occasional slight pain
- USDA D: Painful procedures that will be mitigated by pharmaceuticals.
- USDA E: Painful procedures that will not be mitigated.
Category B states the animal will not feel pain. Animals in this category are often used for breeding, which is a natural process that does not cause animal distress or pain.
Animals in category C may feel the occasional slight pain which is allowed to subside naturally without the use of pharmaceuticals. This may include procedures such as
- Drawing blood samples
- Injections
Animals in category D are exposed to painful or stressful procedures and will receive anesthetics and other chemical agents to mitigate or completely relieve the pain, Whereas E category animals do not receive said assistance.
These categories follow a strict rule. Animals must be categorized according to the most painful procedure it will undergo, so because the experiment will use USDA B, C, and D procedures, the animals must be placed into USDA category D.
