Question

Vampire Squid Perhaps the most frightening of the deep-sea monsters is also the smallest. The vampire squid reaches lengths of only six inches. It is also one of the most ancient of the deep-sea monsters. Scientists believe it to be the last surviving member of its order. To see the vampire squid is to wonder how many kinds of sea creatures have been mashed into this one odd-looking spook. Part squid, part octopus, and part fish, the vampire squid has features of all of these. First, it has large fins at the top of its head that look like ears. Flapping like Dumbo, the squid uses these fins to get around. It also has tentacles and a large bulbous head like an octopus. Its arms, however, are connected by webbing that allows it to form a cloak around itself when frightened. Like the octopus, it can change its colors, even making its cloak so dark that it appears invisible. Remarkably, it has the largest eyes compared to its body size of any creature on earth. Despite its mere six-inch length, its eyes are as big as those of a large dog. With its glowing orbs of eyes and its disappearing tricks, it's no wonder it's named after one of the most feared creatures of legends and folklore: the vampire. These creatures make one wonder not just about the odd members of the deep-sea community, but also what mysterious things inhabit the regions never visited by humans. What may be lurking in the deepest, darkest corners of the deep blue seas? One thing we know for certain, much like the outrageous monsters we conjure in our worst nightmares, the deep ocean is an equally imaginative source of shock, awe, and outright fright. Read this sentence from the third paragraph: First, it has large fins at the top of its head that look like ears. What is the main purpose of this sentence in the paragraph? To introduce a list of features To introduce a new topic To make connections to earlier points To summarize the main idea

Answer 1

I think the best answer here is "To introduce a list of features." Since the sentence uses the word "First", you can get an idea that this sentence will begin to enumerate. Furthermore, its purpose is to make the reader aware that the author is enumerating or listing down the features to support the point.
