Is there a word which means block of text, or section of text? I'm trying to describe how similar discontinuous parts of a paper are, in order to recommend that they be reorganized. Section doesn't work, because section would refer to the formal section that text is in (which includes the block I'm trying to reference, as well as lots of additional text--e.g. section 4.1).
To me, passage has too much of a literary connotation (or refers to something that is specifically singled out through indentation or quotes). But perhaps I'm misinformed. The text I'm referring to is part of a scientific paper. Any suggestions?
