What this topic is

Vocabulary in context (word and phrase meaning) questions ask what a word means as used in a specific line, not what it means in general.

Common words with several meanings are the usual targets, so the most familiar definition is often wrong: run can mean operate, manage, flow or stretch, and only the surrounding sentence decides. ACT stems typically point to a line number and ask what the word most nearly means, followed by short synonyms.

A reliable method is to cover the word, predict a replacement, and test each choice in the sentence. Some items also ask about connotation, the feeling a word adds beyond its dictionary meaning.

Sample questions

Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.

HUMANITIES: This passage is adapted from the essay “A Guide That Knows When to Be Quiet.”

On my first morning as a volunteer at the
Bell Museum of Art, I was given an
audio-guide player and told to test stop
14. Before I had properly faced the bronze
5
dancer, a polished voice announced the
sculpture’s date, alloy, and disputed
attribution. I dutifully checked the
recording for errors. Only when it ended
did I notice the dancer’s left heel
10
hovering above the base. The guide had
supplied information, but it had also
decided the order of my attention.
Audio guides are often praised as doors
into collections. A visitor who does not
15
recognize a saint’s emblem or a weaving
technique can gain context without joining
a scheduled tour. Recorded description can
also make visual objects more accessible
to visitors with low vision. At Bell,
20
devices are included with admission and
offered in six languages. It would be
foolish to dismiss that access simply
because my first stop felt overdirected.
Still, some critics argue that guides
25
replace looking with compliance. Curator
Nia Wren puts the objection sharply: once
headphones begin, visitors follow a route,
stand for the allotted minute, and borrow
the museum’s hierarchy of importance. A
30
bright label reading “Director’s Choice”
can exert the same pressure, but a voice
in the ear feels unusually intimate. It
may settle an object before the viewer
has formed a question.
35
I saw that risk during weekend shifts.
Families sometimes clustered around the
numbered symbol beside a painting while
barely glancing at the canvas. Yet I also
watched a boy replay a description of a
40
carved bowl’s repaired rim, then point out
the seam to his grandfather. These scenes
do not cancel each other. They suggest
that the problem is not whether
interpretation is offered but when it
45
arrives and whether visitors can answer
back.
Bell’s education team tested a revised
guide in one gallery. At each stop, the
first track gave only the work’s title and
50
invited thirty seconds of silent
observation. A soft tone then offered
three choices: materials, historical
setting, or an artist’s question. Visitors
could choose none, one, or all. The team
55
also replaced several anonymous
institutional scripts with short
recordings by people who approached the
works differently.
For the bronze dancer, conservator Luis
60
Ortega described the hidden pin that
supports the lifted heel. Choreographer
Amara Bell explained why the uneven
shoulders suggested a turn rather than a
pose. Student Mina Cho said the dancer
65
looked less graceful than stubborn, “as if
the floor has asked her to stay.” Ortega
initially declined to record his segment
because the pin could not be seen. He
changed his mind after a visitor asked
70
whether the heel’s apparent weightlessness
was an illusion, on the condition that his
recording explain what observation alone
could not reveal.
The trial did not produce a simple
75
victory. Tracking data showed that users
of the revised guide spent longer in the
gallery than users of the old one, but
time is an imperfect measure of attention;
a stalled player also keeps someone in
80
place. In exit cards, more visitors
described specific visual details, while a
few complained that the preliminary
silence felt like a lesson in how to
behave. Wren noted that multiplying voices
85
could make the guide seem less commanding
without surrendering the museum’s power to
choose which voices were recorded.
That counterargument matters. A menu is
not the same as an open forum, and
90
institutional selection does not disappear
when a script becomes conversational.
Nevertheless, the trial offers a useful
synthesis. Museums need not choose between
silent abandonment and nonstop
95
explanation. They can delay commentary,
disclose differences among interpreters,
and create opportunities for visitors to
compare those interpretations with what
they see.
100
The word guide may be the source of some
confusion. It can mean an authority who
knows the route, but it can also mean
temporary company—someone who walks beside
you and occasionally points, without
105
insisting that every detour is an error.
The revised device was most successful
when it behaved like the second kind.
Months later, I returned to the bronze
dancer without a player. I noticed the
110
lifted heel first, but now Ortega’s pin,
Bell’s turn, and Cho’s stubbornness waited
in memory. None had settled the sculpture.
Each had made a different feature
available. A woman beside me studied the
115
figure and asked her friend, “Do you think
she is leaving or arriving?” I had heard
no track offer those alternatives. The
best guide, I thought, might be one that
leaves a visitor with a question the
120
institution did not prepare.

Question 1Easier

As used in line 33, the word “settle” most nearly means:

Show answer

Answer: D — fix the meaning of conclusively.

The concern is that authoritative commentary can determine an object’s meaning before the visitor forms a question. In context, “settle” means to close interpretation rather than to position or pay for something.

Question 2Easier

In the ninth paragraph, describing a guide as “temporary company” (line 103) gives the word “guide” the connotation of:

Show answer

Answer: A — a companion who offers help without controlling every choice.

The author immediately describes this kind of company as walking beside a visitor and pointing only occasionally. The phrase shifts the guide from commanding authority toward supportive companionship.

NATURAL SCIENCE: This passage is adapted from the essay “The Fen That Rose at Noon.”

At Lumen Fen, a shallow wetland enclosed
by pale dunes, the ground appeared to
breathe. Broad carpets of stitch-reed lay
flat on the water at dawn. Near noon, some
5
carpets rose ten or twelve centimeters,
carrying snails, fallen leaves, and even
small stones upward. By nightfall they
settled again. The rise was too broad to
be a wave and too regular to be random.
10
From shore, the motion looked like a tide
arriving in the wrong direction.
I joined botanist Mara Venn there after
Ilya Sorn, the fen’s caretaker, reported
the movement. Ilya suspected a buried
15
spring. He proposed that a daily pulse of
groundwater bowed the reed carpets upward
and that any air beneath them was trapped
only after they rose. Venn reversed that
explanation. The reeds grew through a mesh
20
of threadlike algae, and she believed
oxygen produced by the algae gathered
inside the mesh. In her view, expanding
pockets of gas lifted the carpets; the
water underneath merely filled the space
25
they left.
To test both ideas, we selected six
similarly sized carpets. Beneath each one,
we placed a pressure gauge that would
detect a surge from below. We pushed
30
slender measuring stakes through the
carpets so that a change in height would
tilt them. Clear collection funnels caught
gas escaping from three carpets, while the
other three were covered by identical
35
frames that held removable shade cloth.
Finally, I released a narrow ribbon of
harmless violet dye under every carpet. A
spring pulse should move that dye before
the reeds rose, whereas gas forming within
40
the mesh might lift the reeds first.
The next morning, tiny beads appeared
among the algae soon after sunlight
reached the fen. At first, the stakes
remained upright. As the beads joined into
45
silvery pockets, several stakes began to
lean, showing that their carpets were
swelling. Only then did the violet ribbons
widen beneath them as surrounding water
flowed into the growing space. The
50
pressure gauges registered no surge.
Finally, the upper surfaces visibly
lifted, and gas began spilling into the
funnels. The order did not fit Ilya’s
prediction that water pushed upward first.
55
The carpets differed with age. Young ones,
woven from loosely crossing shoots,
released bubbles through many small
openings and scarcely moved. Mature
carpets contained dense layers of dead
60
stems beneath their living tops. Those
layers held about three times as much gas,
and the mature carpets rose much farther.
Yet age alone was insufficient: even an
old carpet remained low on an overcast
65
day. Its structure supplied storage, but
some other process had to supply the gas.
The shade experiment identified that
process more clearly. Shaded sections
produced few bubbles and stayed nearly
70
flat, while neighboring sections beneath
clear frames rose normally. When we
removed the cloth at midday, the shaded
sections lifted forty-seven minutes later.
Evidently, renewed light did not raise
75
them at once; the algae first had to
produce enough oxygen to fill the internal
spaces faster than it escaped. We also
pierced one raised carpet with hollow
needles. It sagged within minutes as gas
80
hissed out, although the pressure gauge
below it remained steady.
Rising altered more than the carpets’
height. When a mature mat lifted,
oxygen-rich water entered temporary
85
chambers underneath. Silver water-beetle
larvae moved into those chambers and fed
among the dangling algae. At dusk, gas
production slowed, bubbles escaped through
the reeds, and the carpet descended. The
90
larvae departed before the chambers
flattened. During six weeks of
observation, the same pattern returned on
bright days, though the youngest carpets
began participating only after their stems
95
thickened and accumulated a deeper layer
of debris.
The fen, then, was keeping two clocks. The
quick clock was daily: sunlight encouraged
oxygen production, stored gas increased
100
buoyancy, and darkness allowed the carpets
to sink. The slower clock measured the
carpets’ development from leaky young
meshes into mature structures capable of
holding large pockets. Our tests strongly
105
favored Venn’s explanation, though they
did not show that underground springs were
absent from the fen. What looked like
water lifting plants was chiefly a
community of plants and algae lifting
110
itself—and briefly constructing habitat as
it did so.

Question 3Easier

As it is used in line 3, the word breathe most nearly means:

Show answer

Answer: D — rise and fall with a regular rhythm.

The opening describes carpets that lie flat at dawn, rise near noon, and settle by nightfall; “appeared to breathe” names that regular rising and falling, not respiration, rest, or speech.
