Denny asked: Given the sentence "A girl wears gray and yellow uniform with heeled boots while four other girls wear yellow and black costumes with hats." is it true that "Some girls are dressed up and going out for halloween."?.
Le: OK, so how can I answer with some explanation?
Just because these girls are dressed in costumes does not mean they are going out Halloween. These girls may be in a play.
The answer: it is not possible to tell.
