Question

After resting for 1,500 years, Italy's Mount Vesuvius woke up to do enormous damage. (2) The volcano erupted in the early afternoon of August 24, A.D. 79, and the residents of Pompeii, four miles away, were able to see and hear the explosion, which sent a huge black cloud into the sky. (3) _____ a day had passed, Pompeii and its inhabitants were buried under thirty to fifty feet of stones and ash. Question 9 options: a. Also b. Eventually c. During d. Before

Answer 1

I believe the answer is D. Before, because Also and During would make it grammatically incorrect and if you consider the fact that they were able to, "see and hear the explosion," then Eventually would not fit because that makes it sound like it took a bit of time.
