Question 1

1. The project, which took three weeks, was finally finished.
2. The project (which took three weeks) was finally finished. (correct answer)
3. The project (which took three weeks was finally finished.
4. The project—which took three weeks) was finally finished.

Explanation: This question tests CCSS.L.6.2.a: using punctuation (commas, parentheses, dashes) to set off nonrestrictive or parenthetical elements—additional information that can be removed without changing the sentence's core meaning. Restrictive elements are essential to identify which person or thing we're talking about and should NOT be set off with punctuation ('Students who study succeed' - which students? those who study, essential). Nonrestrictive elements add extra information about something already identified and MUST be set off with commas, parentheses, or dashes ('My sister, who lives in Boston, is visiting' - only one sister, location is additional info, not essential to identify her). The test: if you can remove the element and the sentence still makes sense with the same core meaning, it's nonrestrictive and needs punctuation. In this sentence, the parenthetical detail 'which took three weeks' is nonrestrictive because it adds extra information about the project's duration but isn't essential to the core meaning that the project was finished. This means it must be set off with punctuation. Choice B is correct because it correctly uses parentheses on BOTH sides of the nonrestrictive element. The punctuation choice—parentheses—is appropriate because the question indicates this information is a side note, not the main point, and parentheses de-emphasize additional details. Removing the element 'which took three weeks' leaves 'The project was finally finished,' which is still grammatically complete, confirming it's nonrestrictive. Choice C represents a common error—missing the closing parenthesis. Without the closing parenthesis, the nonrestrictive element isn't properly enclosed, creating a serious punctuation error that leaves the parenthetical unclosed. This creates confusion about where the side note ends. To help students punctuate nonrestrictive elements correctly: (1) IDENTIFY the element - find the appositive (renames noun), relative clause (who/which/that + verb), participial phrase (verb form describing noun), or interrupter (parenthetical expression). (2) TEST if restrictive or nonrestrictive - ask 'Is this information essential to identify which one?' If YES (essential) = restrictive, NO commas. If NO (extra detail about already-identified noun) = nonrestrictive, NEEDS punctuation. (3) REMOVAL test - try removing the element. If sentence still makes sense with same core meaning, it's nonrestrictive (needs punctuation). (4) BOTH SIDES rule - nonrestrictive elements need punctuation on BOTH sides (opening and closing comma/dash/parenthesis), not just one side. (5) PUNCTUATION CHOICE for nonrestrictive - Commas (standard, most common): 'My friend, an artist, won'; Parentheses (de-emphasize, extra detail): 'The project (due Friday) is hard'; Dashes (emphasize, dramatic): 'The results—surprisingly good—helped us.' (6) MATCHING PAIRS - Parentheses must always come in pairs (), never leave one unclosed. Key: For side notes and de-emphasized details, use PARENTHESES on BOTH SIDES.

Question 2

1. Jamal’s sister who lives in Dallas is visiting this weekend.
2. Jamal’s sister, who lives in Dallas, is visiting this weekend. (correct answer)
3. Jamal’s sister, who lives in Dallas is visiting this weekend.
4. Jamal’s sister who lives in Dallas, is visiting this weekend.

Explanation: Because Jamal has only one sister, she is already identified, so the clause "who lives in Dallas" just adds extra detail. Extra information like this is nonrestrictive and must be set off with a comma on BOTH sides. The correct sentence places a comma before "who" and after "Dallas," neatly enclosing the extra detail; you could remove the clause and still have a complete sentence: "Jamal's sister is visiting this weekend." The version with no commas at all treats the clause as essential, as if Jamal had several sisters and this told you which one—but he has only one, so it needs commas. The version with only the opening comma (before "who") never closes the extra information, so the reader can't tell where the added detail ends. The version with only the closing comma (after "Dallas") never opens the extra information, so the clause runs into the sentence without a clear starting point. Only the sentence with commas on both sides correctly wraps the nonrestrictive clause.

Question 3

1. Emma's math teacher Mr. Chen assigned a short quiz to the class today.
2. Emma's math teacher (Mr. Chen) assigned a short quiz to the class today.
3. Emma's math teacher, Mr. Chen, assigned a short quiz to the class today. (correct answer)
4. Emma's math teacher, Mr. Chen assigned a short quiz to the class today.

Explanation: Because Emma has only one math teacher, the name “Mr. Chen” is extra information you could remove without confusing which teacher is meant. That kind of nonrestrictive appositive needs a comma both before and after it. The sentence with a comma on each side of “Mr. Chen” does this correctly, so it is the best answer. The choice with no commas at all fails to signal that the name is extra information. The choice that wraps the name in parentheses uses a different mark instead of the commas needed here, and parentheses signal a much weaker aside than an appositive. The choice with a comma only before “Mr. Chen” starts to set the name off but forgets the closing comma, so the pair is incomplete and the sentence reads as if it breaks in the wrong place.

Question 4

1. Amir’s best friend, Carlos, brought the supplies for science class. (correct answer)
2. Amir’s best friend Carlos brought the supplies for science class today.
3. Amir’s best friend, Carlos brought the supplies for science class.
4. Amir’s best friend Carlos, brought the supplies for science class.

Explanation: Because Amir has only one best friend, the name Carlos is extra information, not needed to tell which friend we mean. Extra naming information like this is a nonrestrictive appositive, and it must be set off with a comma on BOTH sides. The correct sentence places a comma before and after Carlos: 'Amir’s best friend, Carlos, brought the supplies.' You can remove 'Carlos' and the sentence still makes sense, which proves the name is extra and needs commas. The choice with no commas around Carlos treats the name as essential, as if we needed it to identify the friend—but Amir has only one best friend, so that is wrong. The choice with a comma only before Carlos opens the extra information but never closes it, so the reader can't tell where the appositive ends. The choice with a comma only after Carlos closes the appositive without opening it, and it wrongly separates the subject 'Carlos' from its verb 'brought.' Remember: extra naming information needs a comma on both sides, not just one.

Question 5

1. The house, on the corner, is painted bright blue.
2. The house on the corner is painted bright blue. (correct answer)
3. The house—on the corner—is painted bright blue.
4. The house, on the corner is painted bright blue.

Explanation: An essential phrase that tells you which house should not be set off with any punctuation at all, so the sentence that reads straight through—“The house on the corner is painted bright blue.”—is correct. The version with a comma before and after the phrase treats it as extra, skippable information, which is wrong here. The version with dashes on both sides does the same thing, signaling a nonessential aside. The version with a single comma after the phrase is wrong two ways: it breaks up an essential phrase and leaves it half-punctuated, which no rule allows. Because “on the corner” is needed to know which house, it stays connected to the sentence with no punctuation around it.

Question 6

1. Keisha’s bike, which has a new bell is parked by the door.
2. Keisha’s bike, which has a new bell, is parked, by the door.
3. Keisha’s bike, which has a new bell, is parked by the door. (correct answer)
4. Keisha’s bike which has a new bell, is parked by the door.

Explanation: Because Keisha has only one bike, the clause 'which has a new bell' is extra information you could remove and still have a complete sentence: 'Keisha's bike is parked by the door.' Extra information like this needs to be closed off with a comma on BOTH sides. The correct choice places one comma before 'which' and one comma after 'bell,' neatly setting off the whole clause. One option puts a comma before 'which' but forgets the closing comma after 'bell,' so the extra clause is never properly finished. Another option correctly sets off the clause but then adds a needless comma inside 'is parked, by the door,' breaking up words that belong together. The last option puts the closing comma after 'bell' but skips the opening comma before 'which,' so again the extra information is fenced on only one side. Only surrounding the clause on both sides shows a reader exactly where the added detail begins and ends.

Question 7

1. The results, surprisingly positive—encouraged the whole class.
2. The results (surprisingly positive, encouraged the whole class.
3. The results—surprisingly positive—encouraged the whole class. (correct answer)
4. The results—surprisingly positive, encouraged the whole class.

Explanation: A nonrestrictive interrupter has to be set off with the SAME kind of mark on both sides. The sentence that opens with a dash and closes with a dash is correct, because both ends match and the extra information is cleanly separated. Watch out for the sentence that begins with a comma but closes with a dash—those marks don't match, so the interrupter isn't properly enclosed. Another version opens with a parenthesis but never closes it, then uses a comma instead, leaving the interrupter half-open. The last version starts with a dash but ends with a comma, again mixing two different marks. Only paired, matching punctuation correctly frames a nonrestrictive interrupter on both sides.

Question 8

1. Maya, sitting in the front row, raised her hand quickly. (correct answer)
2. Maya sitting in the front row, raised her hand quickly.
3. Maya, sitting in the front row raised her hand quickly.
4. Maya sitting in the front row raised her hand quickly.

Explanation: Because Maya is already named, the phrase "sitting in the front row" only adds extra information and needs a comma on each side to separate it from the rest of the sentence. That is why "Maya, sitting in the front row, raised her hand quickly" is correct. The version with a comma only after "row" sets off the wrong side, leaving the front of the phrase attached to Maya's name. The version with a comma only after "Maya" opens the phrase but never closes it, so the phrase runs straight into "raised." The version with no commas at all does not separate the extra information from the sentence, making it read as though the phrase is essential. Only the version with a comma before and after the phrase fences off the extra information the way a nonrestrictive phrase requires.

Question 9

1. The homework (believe it or not) was finished before dinner.
2. The homework, believe it or not was finished before dinner.
3. The homework believe it or not, was finished before dinner.
4. The homework, believe it or not, was finished before dinner. (correct answer)

Explanation: A parenthetical aside must be set off on both sides with matching punctuation, and Choice D uses a comma before and after "believe it or not," which is correct. Choice A uses parentheses on only one side style but the item calls for commas here; more clearly, Choice B and Choice C each place only one comma, so the aside is not closed off on both sides. Choice D is the one that fully brackets the aside.

Question 10

1. The book, that Sofia borrowed from the library, is due tomorrow.
2. The book that Sofia borrowed from the library is due tomorrow. (correct answer)
3. The book, that Sofia borrowed from the library is due tomorrow.
4. The book that Sofia borrowed, from the library, is due tomorrow.

Explanation: A restrictive clause tells which specific book and is essential, so it takes no commas: "The book that Sofia borrowed from the library is due tomorrow." Choice B is correct. Choice A wrongly sets off the essential clause with two commas, Choice C adds only one comma, and Choice D puts commas around "from the library," breaking up the clause, so none is punctuated correctly.
