"Selective" refers to the process of choosing or picking out specific items or individuals from a larger group based on certain criteria. This term is often used in various contexts, such as education, where selective schools admit students based on academic performance or entrance exams. It can also apply to decision-making, where individuals may be selective about the information they consume or the friends they choose. In biology, "selective" can describe processes like natural selection, where certain traits become more common in a population because they offer advantages for survival. Similarly, in marketing, companies may be selective in targeting specific demographics to optimize their advertising efforts.
