Which choice completes the text so that it conforms to the conventions of Standard English?

  1. A. manuscript — a single bound volume — spentCorrect
  2. B. manuscript — a single bound volume, spent
  3. C. manuscript, a single bound volume — spent
  4. D. manuscript — a single bound volume spent

Answer: A. manuscript — a single bound volume — spent

An interrupting phrase opened with a dash must be closed with a dash: 'The manuscript — a single bound volume — spent decades…'

Why the other answers are wrong

B. manuscript — a single bound volume, spent
The interruption opens with a dash but closes with a comma; the pair must match.
C. manuscript, a single bound volume — spent
The marks are mismatched in the other order.
D. manuscript — a single bound volume spent
The interruption never closes, so the sentence loses its structure.
