Why may a prosecutor question a witness during cross-examination?

A prosecutor may question a witness during cross-examination primarily to clarify statements or answers given. This phase of questioning allows the prosecutor to address inconsistencies, ascertain the accuracy of the witness's testimony, and help the jury understand the context or details of what has been stated. By doing so, the prosecutor can strengthen their case and challenge any uncertainties in the witness's narrative.

The other options do not accurately reflect the purpose of cross-examination. Entertainment is not a priority in legal proceedings; closing remarks are typically part of a different phase of the trial, and establishing the date of an incident may occur during direct examination or through other means rather than solely through cross-examination. Thus, the focus during cross-examination remains on clarifying and scrutinizing the testimony given.
