Question

add a comma or semicolon if needed. otherwise, submit the text without any additional punctuation.

in 1958, a landslide following an earthquake created a wave one hundred feet high in alaska’s lituya bay moreover, the wave snapped trees nearly two thousand feet upslope and killed five people.

Explanation:

Step1: Analyze the sentence structure

The first part of the sentence describes a landslide creating a wave, and the second part (starting with "moreover") provides additional related information. When using a conjunctive adverb like "moreover" to connect two independent clauses, a semicolon is needed before "moreover" (and a comma after, which is already present here).

Step2: Apply punctuation rule

We need to place a semicolon before "moreover" to properly connect the two independent clauses. So the corrected text is: "In 1958, a landslide following an earthquake created a wave one hundred feet high in Alaska’s Lituya Bay; moreover, the wave snapped trees nearly two thousand feet upslope and killed five people."

In 1958, a landslide following an earthquake created a wave one hundred feet high in Alaska’s Lituya Bay; moreover, the wave snapped trees nearly two thousand feet upslope and killed five people.
