Read the draft passage. Paragraph 1: A special-collections librarian prepared fragile pamphlets for a new case. The display plan required stable light, temperature, and humidity. Paragraph 2: Paragraph 2 currently gives two sentences: “The librarian separated the rarest pamphlets from the rotating materials. A digital monitor tracked conditions inside the case.” Staff reviewed the readings at the end of each day. Editor note: Combine those closely related complete thoughts into one sentence by using a semicolon and no coordinating conjunction. Which choice follows the note?
