Final answer:
A pessimist is someone who focuses on why a situation is impossible and will retreat from it. They tend to have a negative outlook and expect the worst possible outcome.
Step-by-step explanation:
The term that best describes someone who focuses on why a situation is impossible and will retreat from it is pessimist. A pessimist tends to have a negative outlook and expects the worst possible outcome in a given situation. They often lack confidence and may be more inclined to give up or avoid taking risks.
For example, if a pessimist is presented with a challenging task or problem, they may immediately think about all the reasons why it cannot be accomplished or solve it. This mindset can hinder their ability to overcome obstacles and find solutions.
In contrast, a realist focuses on understanding and accepting the reality of a situation, without necessarily being pessimistic or optimistic. They make assessments based on facts and evidence, rather than relying on their emotions or beliefs.
