You usually can't tell from one single sentence if a parser handles garden path sentences, which involve backtracking (hence the name). Plus, there is a part-of-speech tagger that provides an intermediate layer of nlp analysis, which makes a backtracking involving a change of part-of-speech («houses» being either a verb of a noun) quite harder (yet not impossible). POS taggers improve parsers performance dramatically but usually are an indication that the parser have limited backtracking capabilities. You can try it with «the complex houses married soldiers», houses is erroneously marked as a noun.

Yup. It gets it fundamentally wrong, thinking "complex" is an adjective and "houses" is a noun: the/DT complex/JJ houses/NNS married/JJ and/CC single/JJ soldiers/NNS and/CC their/PRP$ families/NNS But, honest, that's a rotten way to try out NL parsers. Nobody claims Stanford's, or anyone's, parser can handle that sort of thing. It throws human language organs because it's specially engineered to do that. And if it can confuse humans, there's no program that it can't confuse, except for one where the right parse is hard-coded. It's an unfair test, is what I'm saying.
