Question

review the paragraph about sargassum seaweed.
within the atlantic ocean, there is a vast stretch of water known as the sargasso sea. this region is so named because it is home to a type of floating seaweed called sargassum. the seaweed serves as a vital habitat for endangered creatures like sea turtles, which use the dense mesh as a shelter for their newborns. too much sargassum, however, can hurt the environment. in march 2023, a record 13 million tons of sargassum bloomed across the central atlantic. such large amounts of the seaweed can sink to the ocean floor, preventing necessary sunlight from reaching coral reefs and causing them to die. since reefs need sunlight to survive, this seaweed could be extremely harmful. thus, while sargassum is important for marine health, too much of it can disrupt the oceans delicate balance.
why should the bolded sentence be removed?
it provides information that is off topic.
it provides information that is redundant.

Explanation:

The bolded sentence states that reefs need sunlight to survive, which was already established in the prior sentence explaining that Sargassum blocks sunlight and kills coral reefs. This makes the bolded sentence repeat information already provided.

Answer:

It provides information that is redundant.
