Here is the poem "The Soul selects her own Society" by Emily Dickinson.
The Soul selects her own Society —
Then — shuts the Door —
To her divine Majority —
Present no more —Unmoved — she notes the Chariots — pausing —
At her low Gate —
Unmoved — an Emperor be kneeling
Upon her Mat —I’ve known her — from an ample nation —
Choose One —
Then — close the Valves of her attention —
Like Stone
The book SAT II Success: Literature which I use to prepare for the SAT exam (a multiple-choice test for high school students in the US) asks the following question about the poem:
Which of the following elements of style are not present in the poem?
(A) Metaphors
(B) Similes
(C) Grammatical irregularities
(D) Slant rhyme
(E) Figurative language
In my opinion, every choice is present: metaphors ("Valves"), similes ("[l]ike Stone"), grammatical irregularities (punctuation), slant rhyme ("pausing"/"kneeling"), and figurative language (this one includes metaphors and similes).
However, the book says otherwise. Here is an explanation for this question:
The correct answer is (B). Remember to pay special attention to the word except in this question. “Chariots” and “Emperor” are clearly metaphors for wealth and power, which makes choice (A) true. Dickinson is known for her sharp, concrete images, like “Door,” “Chariots,” “Gate,” “Mat,” and “Stone,” making choice (B) untrue because they are not similes. Choices (C), (D), and (E) are clearly evident, and therefore do not meet the criteria of exception. Choice (B) is the right answer.
The book says that "[l]ike Stone" only includes an image of stone, but isn't it a simile?
According to Wikipedia:
A simile (/ˈsɪməli/) is a figure of speech that directly compares two things. Similes are a form of metaphor that explicitly use connecting words (such as like, as, so, than, or various verbs such as resemble), though these specific words are not always necessary.
So why is "[l]ike Stone" not a simile in this poem?
