One of the chief purposes of the commentary is to set forth the reason that led the Committee, or a majority of the members of the Committee, to adopt certain variant readings for inclusion in the text and to relegate certain others readings to the apparatus. On the basis of a record of the voting of the Committee, as well as, for most sessions, more or less full notes of the discussions that proceeded the voting, the present writer has sought to frame and express concisely (a) the main problem or the problem involved in each set of variants and (b) the Committees 's evaluation and resolution of those problems.
