Two questions about this sentence: (1) If you were doing an old-fashioned Kellogg-Reed diagram of it, where would the intensifier "itself" go? As an appositive for "building" or as a modifier of "building"? (2) And what is the subjective complement in the sentence -- "stories" or "high"? I think it is "high" wqith "stories" modifying "high" and "four" modifying "stories." Right? Michael Kischner
