Which document is NOT typically included in the "Protest File"?

The correct choice is the summary of all past contracts. The "Protest File" is a collection of documents that are pertinent to a procurement process, particularly in cases where a bid protest has been filed. Key components of the Protest File typically include the solicitation, relevant evaluation documents, and the abstract of offers, which are essential for reviewing how the procurement was conducted and addressing the specific claims made in the protest.

A summary of all past contracts, while potentially useful for context or understanding previous dealings, does not directly relate to the bid or proposal at hand. It does not provide the necessary information specific to the evaluation process or outcome of the current solicitation, which is the main focus of the Protest File. Therefore, this summary would not be included as part of the official documentation for a specific protest situation.
