If you want to understand the theoretical reasons that led researchers to conduct a study, you would read which section of their article?

The introduction section presents the theoretical background and reasons that led the researchers to conduct the study.

The abstract only summarises the whole paper briefly and cannot detail the rationale.

The discussion interprets results and their implications after the study is done.

The methodology describes how the study was carried out, not why it was undertaken.

The introduction typically ends by stating the aim, hypothesis or research question.

It also reviews prior literature to locate the study within existing knowledge.
