Genre: verbatim
Premise: W follows the (useful) practice of listing a shortened pronunciation key on each right-hand page; L 's failure to do so is a disadvantage, notwithstanding the simplicity of their system, for the user must ferret about to find the description given on page xxii to clarify any question.
Hypothesis: W has no pronunciation guide at all, while L provides one on every page.
Relation: contradiction
