[EX Q]: passage: Dr. Henry Jekyll feels he is battling between the good and bad within himself, thus leading to the struggle with his alter ego, Edward Hyde. He spends his life trying to repress evil urges that are not fitting for a man of his stature. He develops a serum in an attempt to mask this hidden evil. However, in doing so, Jekyll transforms into Hyde, a hideous creature without compassion or remorse. Jekyll has a friendly personality, but as Hyde, he becomes mysterious and violent. As time goes by, Hyde grows in power and eventually manifests whenever Jekyll shows signs of physical or moral weakness, no longer needing the serum to be released.
 question: are dr jekyll and mr hyde the same person?
[EX A]: Yes

[EX Q]: passage: A pteridophyte sensu lato is a vascular plant (with xylem and phloem) that reproduces via spores, and therefore was a member of the former and now invalid taxon Pteridophyta. The term is now used only informally to denominate a fern (monilophyte) or lycophyte. Because pteridophytes produce neither flowers nor seeds, they are also referred to as ``cryptogams''. The pteridophytes include the ferns, horsetails, and the lycophytes (clubmosses, spikemosses, and quillworts). These are not a monophyletic group because ferns and horsetails are more closely related to seed plants than to the lycophytes. Therefore, ``Pteridophyta'' is now an invalid taxon, although the term pteridophyte remains in common parlance, as do pteridology and pteridologist as a science and its practitioner, to indicate lycophytes and ferns as an informal grouping, such as the International Association of Pteridologists and the Pteridophyte Phylogeny Group.
 question: pteridophytes can be referred to as vascular cryptogams comment?
[EX A]:
Yes
