Thoreau relates time to a stream, "I drink at the stream; but while I drink I see the sandy bottom and detect how shallow it is."
The quotations marks (" ") make reference what Thoreau says.
The commas and the semi colons give the reader a better comprehension about what author is saying and feeling.
The other options put wrong puntuactions, which make the reader can confuse about what he is reading
Two Question
The unnecessary adjective is varied;
Many is a quantifier article
Are and offer are verbs
College and courses are nouns.
The only adjective is varied and also it is redundant in the sentence
The correct option is option D ("Prescient").
Prescient is an adjective that refers to the ability of perceiving and understanding events before they even unfold. This is certainly not a common word that you hear every day, <u>it's something extra</u>. So if we're talking about language using a cake as a metaphor, a rare word like "prescient" would liken to an extra ingredient that you add on top, such as frosting on a cake.
Hope this helps!
