Short answer: a dangling modifier is a modifier that describes a word that is not in the sentence. Purdue OWL puts it this way: “A dangling modifier is a word or phrase that modifies a word not clearly stated in the sentence” (Purdue OWL). A misplaced modifier is different. Its word is in the sentence, but the modifier sits next to the wrong word.

On the SAT, modifier questions give you an opening phrase and a blank. The right choice starts with the noun that the phrase describes. Below are the two quiz answers, the one rule, and five SAT practice questions with checked answers.
| Question | Answer |
|---|---|
| Which of these best describes a dangling modifier? | A modifier that describes a word that is not in the sentence |
| Which of these best describes a misplaced modifier? | A modifier that describes a word it is not next to |
| SAT: “Having 9,721 feet of prominence…” and four more | A, C, D, D, D |
Which of these best describes a dangling modifier?
This is a common multiple-choice quiz question. In the version we found online, the first choice is “a modifier that only modifies a verb or adjective.” We could not open the full list of choices, so we do not show letters here. Use this table to pick the right one from any list.

Start 1-day free trial →| If a choice says… | It describes | Right for “dangling”? |
|---|---|---|
| It modifies a word that is not in the sentence (not stated, missing) | A dangling modifier | Yes, pick this one |
| It modifies a word it is not next to | A misplaced modifier | No |
| It modifies the word it is next to | A modifier used correctly | No |
| It only modifies a verb or adjective | What an adverb does | No |
Answer: the choice that says the modifier describes a word that is not in the sentence.
Tutor explanation. “Dangling” means hanging with nothing to hold on to. The phrase has no word to attach to. Take Purdue OWL’s example: “Having finished the assignment, the TV was turned on.” Who finished the assignment? No person is named. The TV did not do homework. Purdue’s fix names the doer: “Having finished the assignment, Jill turned on the TV.”
Which of these best describes a misplaced modifier?
The version we found online has a first choice that also begins “a modifier that only modifies a verb or…”. Use the same table. This time the right choice is the one about position.
Answer: the choice that says the modifier describes a word it is not next to.
Tutor explanation. With a misplaced modifier, the right word is in the sentence. The modifier just sits in the wrong spot. In “She almost drove the car for ten hours,” almost is misplaced. It should say “She drove the car for almost ten hours.” That example and the fix come from the Excelsior Online Writing Lab, which gives the rule: “place your modifiers next to what they’re describing.”
On the test, both errors show up as an opening phrase, a comma and a blank. Our page on SAT modifier questions shows six worked examples, and participial phrase examples with answers has twelve quick ones.
| Dangling modifier | Misplaced modifier | |
|---|---|---|
| Is the right word in the sentence? | No | Yes, in the wrong spot |
| Example | Running at full speed, the finish line came into view. | She almost drove the car for ten hours. |
| Fix | Running at full speed, she saw the finish line. | She drove the car for almost ten hours. |
The one rule for SAT modifier questions
The noun right after the comma must be the thing the opening phrase describes. Use these steps:
- Read up to the comma. That opening phrase is the modifier.
- Name the doer. Ask who or what does the action in the phrase. Decide before you look at the choices.
- Check the first noun after the comma. Cross out every choice that starts with a different noun.
- Pick from what is left. Usually only one choice survives.
Watch the possessive trap. “Known for his jazz, Miles Davis’s recordings still sell” is an error. The first noun is recordings, not Miles Davis. The SAT treats this as wrong, as question 4 below shows.
SAT modifier questions with answers
College Board says these grammar questions measure “the ability to edit text to conform to core conventions of Standard English sentence structure, usage, and punctuation” (College Board, Reading and Writing). The five questions below come from The Test Advantage’s SAT question banks. A tutor re-solved each one, and each answer matches the bank’s answer key. Try each one before you open the explanation.

Topographical prominence is a measure of a mountain’s independence from other mountains. Having 9,721 feet of prominence, ______
Which choice completes the text so that it conforms to the conventions of Standard English?
- Pico do Ramelau, a peak located in Timor-Leste, is ranked by geographers as the world’s 98th most prominent mountain.
- the list of mountains geographers rank as the world’s most prominent includes Pico do Ramelau, a peak located in Timor-Leste, at number 98.
- geographers have ranked Pico do Ramelau, a peak in Timor-Leste, as the world’s 98th most prominent mountain.
- the ranking given by geographers to Pico do Ramelau, a peak located in Timor-Leste, is 98th most prominent mountain in the world.
Answer: A. Pico do Ramelau, a peak located in Timor-Leste, is ranked by geographers as the world’s 98th most prominent mountain.
From the free June 2026 SAT Reading and Writing question bank.
Show the full explanation
What has 9,721 feet of prominence? The mountain. A starts with Pico do Ramelau. B starts with the list, C with geographers, and D with the ranking. A list, a group of people, and a ranking do not have prominence. C is the tempting one because it sounds active and clear, but it says the geographers are 9,721 feet tall.
2. Having trained as astronauts for years… (Answer: C)
Having trained as astronauts for years, ______
Which choice completes the text so that it conforms to the conventions of Standard English?
- August 2, 1991, was when space shuttle Atlantis took flight with five crew members aboard.
- it was August 2, 1991, when five crew members took flight aboard space shuttle Atlantis.
- five crew members took flight aboard space shuttle Atlantis on August 2, 1991.
- space shuttle Atlantis took flight on August 2, 1991, with five crew members aboard.
Answer: C. five crew members took flight aboard space shuttle Atlantis on August 2, 1991.
From the June 2025 SAT Reading and Writing question bank.
Show the full explanation
Who trained as astronauts? People. C starts with five crew members. A starts with a date, B with it, and D with the shuttle. None of those trained for years.
3. Fulfilling their myriad duties with grace and goodwill… (Answer: D)
Fulfilling their myriad duties with grace and goodwill, ______ in 2019.
Which choice completes the text so that it conforms to the conventions of Standard English?
- a total of 8,506,262 departing passengers were boarded by employees at Austin-Bergstrom International Airport
- Austin-Bergstrom International Airport saw a total of 8,506,262 departing passengers boarded by employees
- flights at Austin-Bergstrom International Airport were boarded by a total of 8,506,262 departing passengers
- employees at Austin-Bergstrom International Airport boarded a total of 8,506,262 departing passengers
Answer: D. employees at Austin-Bergstrom International Airport boarded a total of 8,506,262 departing passengers
From the September 2026 SAT Reading and Writing question bank.
Show the full explanation
Who fulfilled their duties with grace? The employees. D starts with employees. A starts with the passengers, B with the airport, and C with the flights. Notice that A and C use passive verbs (“were boarded by”). Passive voice often pushes the real doer out of the first slot, so it is a common sign of a dangling modifier.
4. Containing almost 30,000 entries… (Answer: D)
Emory Sekaquaptewa, a Hopi anthropologist and lexicographer, helped compile a bilingual Hopi-English dictionary published in 1998. Containing almost 30,000 entries, ______
Which choice completes the text so that it conforms to the conventions of Standard English?
- knowledge of the Hopi language was preserved by the dictionary, which was considered a model for future lexicographers.
- future lexicographers considered the dictionary, which preserved knowledge of the Hopi language, as a model.
- the dictionary’s preservation of knowledge of the Hopi language was considered a model for future lexicographers.
- the dictionary preserved knowledge of the Hopi language and was considered a model for future lexicographers.
Answer: D. the dictionary preserved knowledge of the Hopi language and was considered a model for future lexicographers.
From the September 2026 SAT Reading and Writing question bank.
Show the full explanation
What contains 30,000 entries? The dictionary. D starts with the dictionary. C is the possessive trap: it starts with the dictionary’s preservation. The noun there is preservation, and a preservation does not contain entries. That is why the SAT marks C wrong. A starts with knowledge, and B starts with future lexicographers.
5. A calculation that assumes ideal viewing conditions… (Answer: D)
The Southern Delta Aquariid meteor shower has a zenithal hourly rate (ZHR) of 25, meaning that at the shower’s peak, 25 meteors per hour could potentially be seen by a hypothetical observer. A calculation that assumes ideal viewing conditions, ______
Which choice completes the text so that it conforms to the conventions of Standard English?
- an actual viewer’s observed number of meteors in an hour and the ZHR may differ considerably.
- the number of meteors an actual viewer observes in an hour may differ considerably from the ZHR.
- there may be a considerable difference between the number of meteors an actual viewer observes in an hour and the ZHR.
- the ZHR may differ considerably from the number of meteors an actual viewer observes in an hour.
Answer: D. the ZHR may differ considerably from the number of meteors an actual viewer observes in an hour.
From the September 2026 SAT Reading and Writing question bank.
Show the full explanation
This opening is a noun phrase, not an -ing phrase. It renames something, so it is called an appositive. The same rule still applies. What is a calculation that assumes ideal conditions? The ZHR. Only D starts with the ZHR. B is close, but it starts with the number of meteors an actual viewer observes. That is a real count, not a calculation.

Frequently Asked Questions
Which of these best describes a dangling modifier?
A modifier that describes a word that is not in the sentence. Purdue OWL defines it as a word or phrase that modifies a word not clearly stated in the sentence. Pick the choice about a missing word, not the one about a word it is not next to (that is a misplaced modifier).
Which of these best describes a misplaced modifier?
A modifier that describes a word it is not next to. The right word is in the sentence, but the modifier sits in the wrong spot, as in "She almost drove the car for ten hours" instead of "She drove the car for almost ten hours."
How do you answer SAT modifier questions?
Read up to the comma, name who or what does the action in the opening phrase, then pick the choice whose first noun is that doer. After "Having 9,721 feet of prominence," the answer starts with the mountain, "Pico do Ramelau," not "geographers."
Is a possessive noun after the comma correct in an SAT modifier question?
Usually not. In "Containing almost 30,000 entries, the dictionary's preservation of knowledge..." the first noun is "preservation," not the dictionary, so the SAT marks it wrong. The correct choice starts with "the dictionary."
What is the difference between a dangling modifier and a misplaced modifier?
A dangling modifier has no word in the sentence to describe. A misplaced modifier has its word in the sentence but sits too far from it. Both are fixed by putting the right word right next to the modifier.
