Read the passage.

Coral reefs are not just affected by human activity. Other organisms can do damage too. A nasty creature, the flatworm, is messing with the coral. The flatworm lives inside some species of coral. It affects its coral host by feeding on coral tissue and robbing the coral of nutrients it needs to survive.

D) One major pain for coral reefs is the flatworm because it’s destructive.

B. A parasite that is threatening the health of coral reefs is the flatworm.

Explanation:

I used the process of elimination to see which statements were too casual.

In A., the phrase "it's a real problem" sounds like something someone could say to their friends when complaining about something, rather than an informative text.

C. says that it "makes life for coral miserable", which I was unsure of, but found the use of miserable to be interesting, since people rarely project emotions onto corals, of all animals. It's almost like personification, which is not a formal way of expressing an idea.

D. says "one major pain", which, like A., is something a friend could say to you when complaining.

Sorry, I know these explanations are sort of vague, since I go by ear, but it's how I would get the answer.

I hope this helps!

the first proposition is to question economic materialism and victorian christianity. the lines are:

“it moves us not.—great god! i'd rather be

a pagan suckled in a creed outworn; ”

wordsworth is stating that nature no longer interests mankind, that the latter is not “moved” by it and explains that ancient western paganism had a more positive attitude concerning nature since it lacked the perv erted judaeo-christian interpretation of having received the world and all its animals and elements from god to use as we , instead of humans actually being not only part of nature but its wardens, meant to appreciate it and protect it.

the next lines are:

“so might i, standing on this pleasant lea,

have glimpses that would make me less forlorn;

have sight of proteus coming from the sea;

or hear old triton blow his wreathed horn.”

wordsworth here make it very clear that by actually looking and contemplating nature, human beings would reconnect with happiness, serenity and purpose. the use of mythological figures is quite evocative as well, proteus is a greek mythological god of the changing sea. he personifies the sea that changes, which symbolizes the way nature changes and inevitably can change to be destructive not only due to natural causes but to human pollution. furthermore, the sea is even more symbolic since all life originated in the sea so it is not only our past but our future since no life form in our planet can survive without water and if all water is destroyed in earth all life will be gone as well.

he then uses triton which is symbolic of the synthesis of both nature and mankind. triton is a mythological greek god that has the upper body of a man and the lower body of a fish (a merman). this human fish duality evokes the fact that humans are not only human but also part of nature, the fish tail representing nature. the main attribute of this god was that he used a conch shell as a horn to calm the roaring seas. in other words, triton uses nature through science for the benefit of human sailors who risk death during tempests. with the use of such metaphor, wordworth is conveying the message that human technology   is supposed to use nature to preserve nature and thereby humanity as well.
