A more thorough explanation:

A request for reconsideration is a submission made by an applicant after their patent claim has been rejected. This submission includes further arguments that the applicant believes will convince the patent examiner to reconsider their decision.

For example, if an inventor applies for a patent on a new type of bicycle wheel and their claim is rejected, they may submit a request for reconsideration that includes additional evidence or arguments to support their claim. This could include data on the wheel's performance or testimonials from experts in the field.

The purpose of a request for reconsideration is to give the applicant another chance to convince the patent examiner that their invention is worthy of a patent. It is an important step in the patent application process and can often lead to a successful outcome for the applicant.
