Read the passage below. Which punctuation mark should be placed in the blank to ensure the sentence is grammatically correct and internally consistent?
Cevap:Though he never completed a working prototype, Charles Babbage envisioned a device that would lay the foundation for modern computing. The development of this theoretical machine—the Analytical Engine, a general-purpose computer designed to utilize punched cards for programming 【dash】 anticipated the digital age by nearly a century. Babbage’s collaborator, Ada Lovelace, even wrote the first algorithm intended for the engine, cementing their place in technological history.
Cevap
A dash (or em dash) is required to close the nonessential parenthetical phrase that begins with a dash.
A dash is required to close the parenthetical element. Because the parenthetical phrase starts with a dash after 'machine,' it must be closed with a matching dash after 'programming' to maintain consistent punctuation structure.
