Fixes for some test sentences

1) "He runs less miles than John does." is not grammatical. It should be "He runs fewer miles than John does."
2) Regarding to add _advmod(run, more/fewer), I'm sorry that I misunderstood you by the last reply.  For the sentences you listed, the "more/less/fewer" has nothing to do with "run". They are quantifiers for "mile". So the _advmod(run, more/fewer) is not needed for all the cases you listed.  I'll comment my google doc comment soon.
