Background information provides context and details that help readers understand a subject better. It includes relevant facts, historical context, and key concepts that are essential for grasping the main topic. This information can come from various sources, such as books, articles, or expert opinions, and is often presented at the beginning of a discussion or report. In academic writing, background information sets the stage for the main argument or analysis. It may cover aspects like the significance of a topic, previous research findings, or definitions of important terms. For example, when discussing climate change, background information might include its causes, effects, and the scientific consensus surrounding it.
