Answer 1

A citation (or in‑text citation) is an in‑text reference to a source of information.
If a paper is submitted to a journal without in‑text references, it will be rejected due to plagiarism (or improper/insufficient referencing).
Documentation is necessary in order to:
- give proper credit to original authors (avoid plagiarism),
- allow readers and reviewers to verify and follow up on sources,
- support and strengthen your claims by showing the evidence base.
