traces of digital ambition appear in early ____ emerged the edsac machine; in princeton, the ias computer; and in philadelphia, the eniac system. each of these pioneering projects demonstrated the possibility of automating complex calculations at speeds no human could match, setting the stage for modern computer architecture. 17 mark for review which choice completes the text so that it conforms to the conventions of standard english? a computing: in cambridge b computing in cambridge c computing in cambridge; d computing in cambridge:

Explanation:

To determine the correct option, we analyze the structure of the sentence. The text lists locations (Cambridge, Princeton, Philadelphia) where computer - related projects emerged. We need a colon to introduce the list of locations and their corresponding computer projects. Option A uses a colon after "computing" to introduce the first location - project pair ("in Cambridge" and "the EDSAC machine"), which follows the convention of using a colon to introduce a list. Option B lacks the colon, so it doesn't properly introduce the list. Option C uses a semicolon, but a semicolon is not appropriate here as we are introducing a list, not separating independent clauses of equal importance. Option D has an incorrect colon placement as "in Cambridge" is part of the phrase introducing the first project, and the colon should be after "computing" to start the list.

Answer:

A. computing: in Cambridge
