You'll read short excerpts from NLP papers, each containing one use of “rather than.” For each, judge if the sentence annoys you. No source information is shown — papers are mixed and unlabeled.
Dimmer text above/below the main sentence is surrounding context from the source paper — read it if you need it, but judge only the sentence in the middle.
[redacted] stands for a formula, table/figure reference, or citation the extraction pipeline removed (it wasn't part of the "rather than" construction itself) — not a judgment call, and not the same as "garbled."
