A more thorough explanation:

In a civil lawsuit, a request for admission is a legal tool that allows one party to ask another party to admit or deny the truth of a statement under oath. If the other party admits to the statement, it is considered true for the purposes of the trial. This can help simplify the trial and resolve uncontested issues.

For example, in a personal injury case, the defendant may ask the plaintiff to admit that they were not wearing a seatbelt at the time of the accident. If the plaintiff admits to this, it can affect the outcome of the trial and any damages awarded.

Requests for admission can also be used to verify the authenticity of documents. For instance, a party may ask another party to admit that a certain document is genuine.

It's important to note that the rules for requests for admission can vary depending on the jurisdiction. In the Federal Rules of Civil Procedure, Rule 36 governs interrogatories.
