Explanation

A research article includes an introduction, the data, and the data analysis with results as its core components.

The introduction frames the problem, the data supply the evidence, and the analysis yields the findings.

Foreword is a prefatory note common to books, not to journal articles.

Letter of recommendation belongs to applications and appointments, never to the article body.

A standard article also carries an abstract, methodology, discussion and references.

The IMRaD structure organises most empirical research papers.
