In 1943, in the midst of World War II, mathematics professor Grace Hopper was recruited by the US military to help the war effort by solving complex equations. Hopper's subsequent career would involve more than just __ . as a pioneering computer programmer Hopper would help usher in the digital age. Which choice completes the text so that it conforms to the conventions of Standard English? A. equations, though: B. equations, though, C. equations. Though D. equations though

The correct answer is C. equations. Though<br /><br />The sentence is discussing Grace Hopper's initial role in the military, which was to solve complex equations. However, it then goes on to state that her career would involve more than just that, as she would become a pioneering computer programmer and help usher in the digital age. The word "though" is used to contrast the initial role with the later development of her career. Therefore, the correct punctuation would be a period after "equations" and "Though" at the beginning of the next sentence.
