What role does the abstract play in a research article?

The abstract serves as a concise summary of the research article, encapsulating the main objectives, methods, results, and conclusions of the study. This section allows readers to quickly determine the relevance and significance of the research without needing to read the entire document. By highlighting the key findings, the abstract aids in the dissemination of knowledge, ensuring that essential information is accessible at a glance. This makes it a crucial component for researchers and practitioners who may be sifting through numerous articles in their field, looking for studies that align with their interests or needs.

In contrast, the other options do not accurately describe the function of the abstract. Listing references pertains to the references section of a paper. Providing a detailed literature review is typically found in the introduction or literature review section, where the background and context of the study are discussed. Outlining the study's methodology is generally reserved for a dedicated methodology section, where comprehensive details about how the research was conducted are presented.
