Answer:
A. It helps the reader understand the implication of events better than the narrator could.
Explanation:
By definition, dramatic irony is the phenomenon of the reader knowing more about the reality of the matter than the characters themselves.
This literary technique in especially useful in works with unreliable narrators because it gives the reader the opportunity to know and understand the plot of the story independently of the narrator's words. In other words, the reader does not need to rely on the characters to understand the events of the work, thus being able to detect unreliability, where present.
Every planet in the solar system has seasons. Most have four like the Earth -- called Winter, Spring, Summer and Fall -- but that's where the similarities end.
The rhyme scheme consists of a discernible pattern of rhymes (words corresponding to other words in sounds) at the end of the lines, or in the middle. In this case, the rhyme scheme is as follows: ABBAABBACDCDCD. Look at the ending words of each line, and you'll notice the pattern: "saint" - "grave" - "gave" - "faint" (the first rhymes with the fourth, and the second rhymes with the third); the same with "taint" - "save" - "have" - "restraint". The rest of them: "mind" - "sight" - "shin'd" - "delight" (the first and the third rhyme with each other, just like the second and the fourth), etc.
