Investigation is a systematic process used to gather information and uncover facts about a specific subject or event. It often involves collecting evidence, interviewing witnesses, and analyzing data to understand what happened. Investigations can be conducted in various fields, including law enforcement, science, and journalism. The goal of an investigation is to find the truth and provide clarity. For example, a police investigation may seek to solve a crime, while a scientific investigation aims to test a hypothesis. Regardless of the context, investigations rely on critical thinking and careful examination of all available information.
