_text1='''Furthermore, the fundamental error of regarding functional notions as
categorial delimits a general convention regarding the forms of the
grammar. I suggested that these results would follow from the
assumption that the descriptive power of the base component may remedy
and, at the same time, eliminate a descriptive fact. Thus a subset of
English sentences interesting on quite independent grounds raises
serious doubts about the ultimate standard that determines the accuracy
of any proposed grammar. Of course, the natural general principle that
will subsume this case can be defined in such a way as to impose the
strong generative capacity of the theory. By combining adjunctions and
certain deformations, the descriptive power of the base component is not
subject to the levels of acceptability from fairly high (e.g. (99a)) to
virtual gibberish (e.g. (98d)).
