The term "multiple techniques" refers to a variety or combination of different methods, approaches, or procedures used in achieving a particular goal. It can be applied in various fields such as science, technology, business, and education, among others. In essence, it means using more than one way to solve a problem or complete a task, rather than relying on just one method alone. The idea behind this is that by employing different approaches, the chances of finding an effective solution are increased, as well as reducing the risk of failure due to dependence on a single approach.
