Question

read the summary of the article below. this article is about real - life sea monsters. for example, a giant octopus can grow to up to 20 feet, though it would only be big enough to sink a small sailboat. however, giant squids can grow up to 160 feet long. they have even been reported to attack ships. additionally, oarfish can grow up to 50 feet long. a sick oarfish may surface and be mistaken for a giant sea serpent. its possible that someday scientists will discover more animals in the sea that explain other sea monsters. which detail should be added to the summary? ○ hopefully sea monsters will no longer attack ships. ○ terrified sailors would try to get their ships away from sea monsters. ○ there were more creatures than just the kraken that people believed lived in the ocean. ○ according to the article, legends of sea monsters that sink ships may be based on real - life creatures.

Explanation:

The article discusses real - life sea creatures (giant octopus, giant squids, oarfish) that could be mistaken for sea monsters. The correct detail to add should relate to how sea monster legends (like those sinking ships) may come from real - life creatures. The first option is a hope not related to the article's focus on real - life basis. The second is about sailors' actions, not the article's main idea. The third mentions the kraken, which isn't in the article. The fourth connects sea monster legends (sinking ships) to real - life creatures, matching the article's content.

Answer:

D. According to the article, legends of sea monsters that sink ships may be based on real - life creatures.
