Passage Serpent Mound
Serpent Mound
The Great Serpent Mound, located in Adams County, Ohio, is a human-made mound of earth that researchers believe was created between 300 B.C. and A.D. 1100 by an indigenous culture.
Ohio, 1846
Brush Creek stood low when the museum men came
with their measuring tapes and sketchbooks.
It was winter. Fringed with ice,
the creek doubled back on itself
as if it had forgotten something.
Pa was in Cincinnati, or else on his way home,
so Ma told me to lead the men
into the marshy low grounds. It being winter,
there was little underbrush to speak of—
in the summer there would have been
briars, poison ivy, biting flies. I listened
for the swish of a beaver’s heavy tail,
the chitter of a chickadee, or the cry of a hawk,
but the winter silence of the creek pressed
down on all of us like a weight.
The humps in the ground were all but
invisible until you were right up on them. The figure
was even less obvious: the sinuous body,
the tail coiled three times around,
and at the other end, the mouth wide open.
In the summer the creek bottom was crowded
with so much life that you could trip over
the ridges of earth before you saw
anything at all. In winter you could climb
a tree and get some idea of the whole thing:
the serpent’s body undulating, slithering
silently across the ancient
earth. At the mouth end, there was an oval mound
as if the snake were about to swallow an egg—
as snakes sometimes did in our rickety
henhouse—my Pa always said, or
as if swallowing the sun, one of the museum
men suggested, taking notes with his quill pen,
an old-style inkhorn slung at his side.
I liked that: swallowing the sun,
just the sort of thing a snake might do,
might want to do. When, later, I told my sister Ruth,
she disagreed. It is singing to the sun,
she insisted. That is why its mouth
is wide open. She said, “Sometimes I think
I hear it on summer nights. Not swallowing, singing.”
Question
Read line 28 from the poem.
At the mouth end, there was an oval mound
How does the line contribute to the development of ideas in the poem?
- AIt describes a feature of the mound that the men from the museum need to document.
- BIt introduces a comparison of the body of the mound with the head of the mound.
- CIt introduces a feature of the mound that has a different meaning to different people.
- DIt describes a part of the mound that is difficult to see from far away.
Show the answer
Correct answer: C
The question asks how line 28 contributes to the development of ideas in the poem.
A. Incorrect. Although the museum men are documenting the shape of the mound in line 33, lines 29–32 and 35–41 focus on what the oval mound represents as interpreted by the museum men, the speaker, and the speaker’s sister.
B. Incorrect. While the lines preceding line 28 describe the body of the snake in detail (“you could climb / a tree and get some idea of the whole thing: / the serpent’s body undulating, slithering / silently across the ancient / earth” [lines 24–28]), the purpose of line 28 is to begin the development of the ideas about the oval shape at the end of the mound: the serpent’s mouth.
C. CORRECT. Line 28 introduces the presence of the oval mound at the mouth of the snake. The meaning of this oval is of great interest to the museum men and the speaker. Line 28 leads to the idea that there is speculation about the oval mound (“as if the snake were about to swallow an egg” [line 29], “as if swallowing the sun” [line 32], and “It is singing to the sun” [line 38]).
D. Incorrect. The speaker does not say that the oval shape near the end of the mound is difficult to see. Earlier, the speaker says that the ridges of earth are difficult to see unless you are near them, but the speaker does not say this about the oval shape.
Question analysis
Students explain how line 28 of “Serpent Mound,” which introduces an oval mound at the serpent’s mouth end, contributes to the development of ideas in the poem. The line is a plain piece of description in a poem about museum men surveying the mound, so students must work out what part it plays in the poem as a whole.

Why it is hard, traps and wrong answers (shows the answer)
Why it is hard
Because the museum men came to measure and sketch, a line naming a new feature looks like a note for their records, and that reading is the strong pull. Others see a comparison with the serpent’s body described just before, or carry over the earlier point about humps that are hard to see. The line’s job shows in what follows it: the oval is where Pa, a museum man and Ruth each see something different.
A very close wrong answer moderate Choosing the answer
The documenting choice and the key both say line 28 presents a feature of the mound; they differ in what follows, the men’s records or the egg, sun and singing readings in lines 29–41. (Embretson & Wetzel, 1987; Gorin & Embretson, 2006; Ascalon et al., 2007)
How, not what moderate Working it out
The line is plain description, so its role shows only in what it sets up: the oval becomes the egg, the swallowed sun and the open singing mouth that the rest of the poem weighs. (Anderson & Krathwohl, 2001)
Evidence in several places minor Working it out
The readings are spread over thirteen lines and three people, Pa in lines 29–31, a museum man in lines 32–33 and Ruth in lines 37–41, so students must gather them. (Kirsch & Mosenthal, 1990; Gorin & Embretson, 2006)
Strategy: Read line 28 together with the lines on either side of it, then test each choice against what those lines actually show.
Traps
- True but not the answer: A choice says something accurate about the text that does not answer this question.
- Wrong part of the text: A choice is true of another paragraph, stanza or speaker than the one asked about.
- Wrong purpose or structure: Names a purpose, structure or effect that the part does not serve, or describes what a part says when the question asks what it does.
The wrong answers, classified
A True but not the answer (King et al., 2004; Embretson & Wetzel, 1987)
Knows the men came “with their measuring tapes and sketchbooks,” so any new feature seems one to record, but the lines after 28 dwell on what the oval means, not on recording it.
B Wrong purpose or structure (Anderson & Krathwohl, 2001)
Notices that lines 24–28 describe the serpent’s body just before the oval appears, but line 28 moves on to the mouth end and never sets head and body side by side.
D Wrong part of the text (Kirsch & Mosenthal, 1990)
Carries over lines 16–17, where the humps are “all but / invisible” until you are close, to the oval mound, which the poem never calls hard to see.
Working it out, step by step
Figure out what the question asks
This asks how one line helps build the poem’s ideas. Line 28 is a plain description: “At the mouth end, there was an oval mound.” Oval means egg-shaped. To see the line’s job, look at what comes right after it.
Read what follows line 28
The next lines give three ideas about the oval mound.
- Pa always said it was “as if the snake were about to swallow an egg,” as snakes did in the family’s henhouse (lines 29–31).
- A museum man says “as if swallowing the sun” (line 32).
- Ruth says “It is singing to the sun” (line 38).
Name the line’s job
Line 28 brings in the oval mound. Then each person sees something different in it: an egg, the sun being swallowed, or a song. Each idea comes from that person’s own life. Pa thinks of his henhouse. Ruth thinks of what she seems to hear on summer nights. So the line sets up a feature that means different things to different people.
Check each choice
- A does not fit. The men did come to measure and sketch. But the lines after 28 are about what the oval means, not about recording it.
- B does not fit. Line 28 moves on from the body to the mouth. It never compares the two.
- C fits. The oval gets three different meanings from three people.
- D does not fit. Lines 16–17 say the humps are hard to see. The poem never says that about the oval.
Watch out: A is tempting because the men came “with their measuring tapes and sketchbooks.” But the poem spends its last 13 lines on meanings, not measurements.
Choose the answer
Line 28 brings in the oval mound that Pa, a museum man and Ruth each see in their own way. So the answer is C, “It introduces a feature of the mound that has a different meaning to different people.”
Why this answer and not the closest wrong one
A is the closest wrong choice. The museum men are there to document, or record, the mound, and one is taking notes. But the lines after 28 are not about notes. They give an egg, a swallowed sun and a singing snake. That is a feature with a different meaning to different people, just as C says.
