Hi,
In a test of detection of errors, candidates are asked to explain errors in the given sentences. After reading the mock examination answers, I found that the answers had such terms as "discourse error", "sentence error" and "part of speech problem". Could somebody explain them to me? Thank you in advance.

1. The two cases of error are ambiguous. Thesephrases could mean either grammatical or syntactic error. The difference may be important.
2. "Part of speech problem" seems to relate toparsing, of which the first task is identifying each word by function, as a noun, verb, adjective, adverb, preposition etc. These are the Parts of Speech.
A PoS error is a mistaken identification, e.g.
identifying an adjective as an adverb. ("PoS problem" is almost meaningless. We know what an error is,
but anything at all can be a "problem" without
informing us whether the PoS is identified rightly or wrongly.)
