* Biological race: This refers to a group of people sharing certain physical characteristics, often associated with a common geographic origin. This definition is now largely considered outdated and scientifically invalid as it doesn't accurately reflect the complex genetic diversity of humans.
* Race as a competition: This refers to a contest, often involving speed or skill, with the goal of being the first to finish. This definition is completely unrelated to the biological definition and focuses on a specific event or activity.
Therefore, the word "race" can be seen as having opposite meanings in the context of human categorization and competitiveness. It's crucial to understand the context in which the word is used to avoid misunderstanding and potential harm.
