The questions were mostly contributed by participants or developed by
NIST assessors. A few questions were mined from the FAQFinder system's logs.
The test set consisted of 200 questions. Two questions, questions 131 and 184,
were not used when computing final scores because it was determined during

could train their systems.
The format for each question is a question number, the text
of the question, and then one or more answer strings followed by
the id of a document that supports the answer.
