All questions

Question 1

Fix this fragment from Marcus's note: "Played tag at recess."

  1. At recess played tag and ran.
  2. They it played tag at recess.
  3. Marcus played tag at recess. (correct answer)
  4. The kids played tag. At recess.
Explanation: The words "Played tag at recess" tell what happened, but they never tell WHO did it, so the thought is not complete. To fix a fragment like this, you add the missing subject. "Marcus played tag at recess" names who played (Marcus) and tells what he did (played tag at recess), so it is a complete sentence — this is the correct answer. "At recess played tag and ran" still never says who played or ran, so it is still missing a subject. "They it played tag at recess" has two subject words jammed together ("They it"), which makes it confusing and not a clear sentence. "The kids played tag. At recess." breaks one idea into two pieces; "The kids played tag" is fine, but "At recess." standing alone is only a small phrase, not a sentence. Always ask "Who or what did it?" to find a missing subject.

Question 2

Fix the fragment from Keisha's report: "The tall tree in our yard."​

  1. The tall tree in our yard.
  2. The tall tree in our yard, it gives shade.
  3. The tall tree in our yard gives shade. (correct answer)
  4. Because the tall tree in our yard gives shade.
Explanation: This question tests CCSS.L.4.1.f: producing complete sentences and recognizing and correcting inappropriate fragments and run-ons. Students must identify complete sentences (subject + predicate + complete thought) versus fragments (incomplete). A complete sentence has three parts: a SUBJECT (who/what it's about), a PREDICATE (what the subject does/is - includes a verb), and a COMPLETE THOUGHT (makes sense alone). A FRAGMENT is missing one of these parts - common types include missing predicate where we have a subject but no verb/action. In this fragment, 'The tall tree in our yard' is missing a predicate - we have a subject 'The tall tree' with descriptive details 'in our yard,' but we don't know what the tree does or is (no verb). Choice C is correct because it adds the missing predicate 'gives shade' to create 'The tall tree in our yard gives shade,' which now has subject (tree), predicate (gives shade), and complete thought. Choice B represents a comma splice error, which occurs when students try to fix fragments by adding information incorrectly. 'The tall tree in our yard, it gives shade' joins two complete thoughts with just a comma - 'The tall tree in our yard' is still a fragment, and 'it gives shade' is a complete sentence, creating an incorrect combination. The correct fix is to make one complete sentence, not join a fragment to a sentence. To help students: Teach the 'complete sentence test' focusing on finding the verb - what does the subject DO or what IS it? Practice identifying predicates: circle subject, underline verb/predicate. Common fragments include missing predicate ('The small bird' - what about it?) which students miss because the phrase has good description. Watch for: thinking 'The big brown dog' is complete (missing predicate/verb), trying to fix fragments by adding comma and new sentence instead of completing the original thought, and not recognizing that every complete sentence must have a verb.

Question 3

In Yuki's story, what is wrong with: "I packed my lunch, I forgot my apple."?

  1. It is a fragment missing a subject.
  2. It is a comma splice run-on. (correct answer)
  3. It is a complete sentence.
  4. It needs a question mark.
Explanation: This question tests CCSS.L.4.1.f: producing complete sentences and recognizing and correcting inappropriate fragments and run-ons. Students must identify complete sentences (subject + predicate + complete thought) versus fragments (incomplete) and run-ons (two sentences incorrectly joined). A RUN-ON is two complete sentences incorrectly joined together - a comma splice occurs when only a comma joins two complete sentences without a conjunction. In this example, 'I packed my lunch, I forgot my apple' is a run-on. Two complete sentences ('I packed my lunch' and 'I forgot my apple') are joined with only a comma, creating a comma splice. Choice B is correct because it correctly identifies this as a comma splice run-on - the comma alone cannot properly join these two complete sentences without a conjunction like 'but.' Choice A represents a common error where students focus on missing subjects in fragments but don't recognize run-ons - both parts here have subjects and are complete sentences incorrectly joined. To help students: Teach to identify comma splices by finding commas between two complete thoughts - if both sides could stand alone as sentences, need more than just comma. Practice fixing comma splices three ways: (1) Period: 'I packed my lunch. I forgot my apple.' (2) Comma + conjunction: 'I packed my lunch, but I forgot my apple.' (3) Semicolon: 'I packed my lunch; I forgot my apple.' Watch for: thinking any sentence with comma is correct, not recognizing both parts are complete sentences, missing that comma alone can't join complete sentences.

Question 4

Read: "Carlos washed the dishes, he dried them." Is it a fragment, run-on, or complete sentence?​​

  1. Run-on sentence (correct answer)
  2. Fragment sentence
  3. Complete sentence
  4. Compound word
Explanation: The correct answer is run-on sentence. This example has two complete thoughts: "Carlos washed the dishes" and "he dried them." Each one has its own subject and verb, so each could stand alone. When two complete thoughts are joined by only a comma, you have a run-on. To fix it, you could use a period, or add a joining word like "and" after the comma. It is not a fragment, because a fragment is missing part of a complete thought, like "Washed the dishes." Both parts here are complete, so nothing is missing. It is not a complete sentence, because a single complete sentence has just one main thought, and one comma is not enough to correctly connect two thoughts. It is not a compound word, because a compound word is two small words joined into one word, like "dishwasher" or "cannot" — that describes a word, not a whole sentence.

Question 5

In Carlos's story, which sentence is a run-on that needs fixing?

  1. Carlos rode his bike to the park after school.
  2. After school, Carlos rode his fast red bike.
  3. Carlos rode his bike he wore a blue helmet. (correct answer)
  4. Carlos and Amir played basketball in the yard.
Explanation: The correct answer is "Carlos rode his bike he wore a blue helmet." This is a run-on because it jams two complete thoughts together with no punctuation between them. "Carlos rode his bike" is one whole sentence, and "he wore a blue helmet" is another whole sentence. You could fix it with a period ("Carlos rode his bike. He wore a blue helmet.") or with a comma and a joining word ("Carlos rode his bike, and he wore a blue helmet."). "Carlos rode his bike to the park after school" is not a run-on. It is one complete thought, just with extra details added on. A long sentence is not automatically a run-on. "After school, Carlos rode his fast red bike" is also one complete sentence. Starting with an extra part like "After school" does not make two thoughts, so it is fine. "Carlos and Amir played basketball in the yard" has two names doing one action, but it is still only one complete thought, so it is not a run-on. Read each choice slowly and listen for two separate ideas crashing together with nothing between them.

Question 6

Fix this run-on from Chen's writing: "The bell rang we lined up."

  1. The bell rang, we lined up.
  2. The bell rang. We lined up. (correct answer)
  3. Because the bell rang we lined up.
  4. The bell rang, so we lined up soon.
Explanation: The original sentence is a run-on: two complete thoughts, "The bell rang" and "we lined up," are jammed together with no punctuation. The best fix separates them into two clear sentences with a period: "The bell rang. We lined up." Each part now has its own subject and verb and stands on its own. Using only a comma between the two thoughts is still a run-on, called a comma splice — a comma alone is not strong enough to join two complete sentences. Starting with "Because" makes the sentence an incomplete thought (a fragment); it leaves you waiting to hear what happened because the bell rang. Adding "so" this way keeps the comma error because "so" needs to follow a comma correctly to join two sentences, and even then the extra word "soon" does not repair the punctuation between the two thoughts. To fix run-ons, you can split them with a period, join them with a comma plus a joining word like and, but, or so, or add a word like when or because to one part.

Question 7

Which best corrects Carlos's run-on: "I like drawing it helps me relax."

  1. I like drawing; it helps me relax. (correct answer)
  2. I like drawing it really helps me relax.
  3. I like drawing, it helps me relax.
  4. Because I like drawing it helps me relax.
Explanation: The original sentence is a run-on: two complete thoughts, "I like drawing" and "it helps me relax," are jammed together with no punctuation. Using a semicolon between the two related thoughts fixes it, because a semicolon can join two complete sentences that go together. "I like drawing it really helps me relax" just adds the word "really" but still runs the two thoughts together with no punctuation, so it is still a run-on. "I like drawing, it helps me relax" tries to fix it with only a comma, but a comma alone cannot join two complete sentences—that is a comma splice. "Because I like drawing it helps me relax" adds a word but makes the first part depend on the second and leaves the thoughts joined without correct punctuation, so it is not fixed either. Only the semicolon separates the two complete thoughts correctly.

Question 8

Which of these is a complete sentence?

  1. Because Yuki read a book about horses.
  2. Yuki read a book she liked it a lot.
  3. Yuki read a book and wrote a summary. (correct answer)
  4. Wrote a summary about the book she read.
Explanation: "Yuki read a book and wrote a summary." is a complete sentence. It has a subject (Yuki) and tells two things she did, and it expresses a full thought all by itself. "Because Yuki read a book about horses." is a fragment: the word "because" makes you expect more, but the idea never finishes. "Yuki read a book she liked it a lot." is a run-on, because it jams two complete thoughts together with no period or connecting word between them. "Wrote a summary about the book she read." is missing a subject: it tells what was done, but never says who did it, so it is also a fragment.

Question 9

Is this a complete sentence, fragment, or run-on: "When Maya got home."?

  1. Complete sentence
  2. Run-on
  3. Fragment (correct answer)
  4. Comma splice
Explanation: This question tests CCSS.L.4.1.f: producing complete sentences and recognizing and correcting inappropriate fragments and run-ons. Students must identify complete sentences (subject + predicate + complete thought) versus fragments (incomplete) and run-ons (two sentences incorrectly joined). A complete sentence has three parts: a SUBJECT (who/what it's about), a PREDICATE (what the subject does/is - includes a verb), and a COMPLETE THOUGHT (makes sense alone). A FRAGMENT is missing one of these parts - dependent clause fragments start with words like 'when,' 'because,' or 'if' but don't complete the thought. In this example, 'When Maya got home' is a fragment. It is a dependent clause that doesn't express a complete thought - we don't know what happened when Maya got home. Choice C is correct because it correctly identifies this as a fragment - the dependent clause needs a main clause to complete the thought, like 'When Maya got home, she did her homework.' Choice A represents a common error where students think any group of words with subject and verb is complete, but dependent clauses starting with 'when,' 'because,' 'if,' etc. create incomplete thoughts. To help students: Teach that dependent words (when, because, if, although, since) make incomplete thoughts that need main clauses. Practice completing dependent clause fragments by asking 'What happened?' - 'When Maya got home, [what happened?].' Common fragments: Dependent clause alone (starts with because/when/if but doesn't tell what happened). Watch for: not recognizing dependent words create fragments, thinking any clause with subject and verb is complete, missing that reader is left asking 'then what?'

Question 10

Which choice fixes the sentence fragment: "Ran to the playground after lunch."?

  1. After lunch, quickly ran to the playground.
  2. Jamal ran to the playground after lunch. (correct answer)
  3. Because Jamal ran to the playground after lunch.
  4. When Jamal ran to the playground after lunch.
Explanation: The fragment is missing a subject, so we need to know who ran. Adding the name Jamal gives us both a subject and a verb, making a complete sentence that can stand on its own. One choice just reorders the words and adds "quickly," but it still never tells us who ran, so it stays a fragment. Another choice starts with "Because," which turns it into a dependent clause that leaves the reader waiting for the rest of the idea. The last choice starts with "When," which does the same thing: it sounds unfinished and cannot stand alone as a sentence. Only the choice naming Jamal fixes the fragment completely.

Question 11

What is missing from Amir's sentence "My new soccer ball." to make it complete?

  1. A predicate (what happens) (correct answer)
  2. A subject (who or what)
  3. A second sentence (another idea)
  4. A comma and joining word (to connect)
Explanation: A complete sentence needs a subject (who or what) and a predicate (what happens). "My new soccer ball" already names a subject, but it never tells what the ball does or is, so it is a fragment. Adding a predicate fixes it, like "My new soccer ball rolled away" or "My new soccer ball is blue." The choice about needing a subject is wrong because the sentence already has one — the soccer ball. The choice about adding a second sentence is wrong because you don't need another idea; you need to finish this one. The choice about a comma and joining word is wrong because those connect two complete sentences, and here you only have one unfinished part. So the missing piece is a predicate that tells what happens.

Question 12

Which best corrects this comma splice: "Maya drew a cat, Marcus colored it."​​

  1. Maya drew a cat Marcus colored it.
  2. Maya drew a cat. Marcus colored it. (correct answer)
  3. Maya drew a cat, Marcus colored it.
  4. Because Maya drew a cat, Marcus colored it.
Explanation: This question tests CCSS.L.4.1.f: producing complete sentences and recognizing and correcting inappropriate fragments and run-ons. Students must identify complete sentences (subject + predicate + complete thought) versus fragments (incomplete) and run-ons (two sentences incorrectly joined). A RUN-ON is two complete sentences incorrectly joined together - a comma splice uses just a comma between complete sentences, which is incorrect. In this example, 'Maya drew a cat, Marcus colored it' is a comma splice run-on. Two complete sentences ('Maya drew a cat' and 'Marcus colored it') are joined with only a comma. Choice B is correct because it properly separates the two sentences with a period: 'Maya drew a cat. Marcus colored it.' Choice C represents the original comma splice error, which occurs when students think a comma alone can join two complete sentences. A comma by itself cannot join two complete sentences - you need either a period to separate them or a comma plus a conjunction (and, but, so, or). Choice D also corrects the run-on by making the first part dependent with 'Because,' creating one complex sentence. To help students: Teach to read slowly and listen for two complete thoughts - if joined by only a comma, it's a comma splice run-on. For run-ons, teach three correction strategies: separate with period, join with comma+conjunction, or use dependent word to make one part dependent. Common run-ons include comma splice (comma alone between sentences). Watch for: using comma alone to join sentences (need comma + conjunction like 'and'), thinking any sentence with a comma between clauses is correct, and not recognizing that two subject-predicate combinations usually mean two sentences.

Question 13

Read: "When the bell rang." Is it a fragment, run-on, or complete sentence?

  1. Run-on
  2. Complete sentence
  3. Fragment (correct answer)
  4. Simple sentence
Explanation: "When the bell rang" is a fragment because it is a dependent clause that does not express a complete thought on its own. Answer A is wrong because a run-on joins two complete sentences without proper punctuation, which this is not. Answer B is wrong because the clause needs more information to be complete, such as what happened when the bell rang. Answer D is wrong because a simple sentence must be a complete thought, and this clause is not.

Question 14

Which choice correctly fixes this run-on sentence: "The bell rang we lined up."?

  1. The bell rang, we lined up.
  2. The bell rang. We lined up. (correct answer)
  3. Because the bell rang we lined up.
  4. The bell rang and we lined up.
Explanation: The correct answer fixes the run-on by splitting it into two complete sentences with a period. Choice A is wrong because a comma alone cannot join two complete sentences; this is called a comma splice. Choice C is wrong because it starts a dependent clause but leaves out the comma that should follow it. Choice D is wrong because it needs a comma before "and" to correctly join the two complete thoughts.

Question 15

Which choice fixes the sentence fragment: "Ran to the playground after lunch."?

  1. Ran to the playground after lunch.
  2. He ran to the playground after lunch. (correct answer)
  3. Because he ran to the playground after lunch.
  4. He ran to the playground after lunch, he played tag.
Explanation: Choice B is correct because it adds a subject, making it a complete sentence. Choice A repeats the original fragment, which still has no subject. Choice C adds "because," turning it into a dependent clause that cannot stand alone. Choice D joins two complete sentences with only a comma, which creates a run-on.

Question 16

Which sentence correctly fixes this run-on: "Sofia finished her book she told Chen about it."

  1. Sofia finished her book. She told Chen about it. (correct answer)
  2. Sofia finished her book she told Chen about it.
  3. Sofia finished her book, she told Chen about it.
  4. Because Sofia finished her book, she told Chen.
Explanation: The correct answer is A because it splits the run-on into two complete sentences with correct end punctuation. Choice B is wrong because it is the same run-on sentence with no fix at all. Choice C is wrong because it only adds a comma, which creates a comma splice instead of fixing the run-on. Choice D is wrong because it changes the meaning by making the second idea sound like it only happened because of the first.

Question 17

Which sentence is written correctly and is not a fragment or run-on?

  1. Although Emma was tired.
  2. Emma was tired, she went to bed early.
  3. Went to bed early.
  4. Emma was tired, so she went to bed early. (correct answer)
Explanation: A complete sentence needs a full subject and verb without being a fragment or a run-on. The first choice is a fragment because it starts with although and never finishes the thought. The second choice joins two full sentences with only a comma, which is a run-on. The third choice is a fragment with no subject. The fourth choice correctly joins two full sentences using a comma and the word so.

Question 18

Which sentence is written correctly for Maya's journal entry about art class?

  1. Because Maya used bright colors in her painting.
  2. Maya painted a sunset during art class. (correct answer)
  3. Painting a sunset, Maya during art class.
  4. Maya painted a sunset, she showed it to her teacher.
Explanation: "Maya painted a sunset during art class." has a subject and a complete verb phrase, so it expresses a full, correct thought. Choice A is a fragment that begins with a dependent clause and never finishes the thought, choice C is a fragment missing a main verb, and choice D joins two complete sentences with only a comma, creating a comma splice.

Question 19

In Jamal's journal, is "Ran to the bus stop." a fragment, run-on, or complete sentence?

  1. Complete sentence
  2. Fragment (correct answer)
  3. Run-on
  4. Compound sentence
Explanation: Fragment is correct because "Ran to the bus stop" has no subject telling who ran, so it cannot stand alone as a complete thought. It is not a complete sentence because it is missing a subject. It is not a run-on because a run-on joins too many complete thoughts together, not too few. It is not a compound sentence because it does not join two complete sentences with a conjunction.

Question 20

Fix this run-on: "Sofia finished her math she started reading." Which option correctly fixes the run-on sentence?

  1. Sofia finished her math, she started reading.
  2. Sofia finished her math. She started reading. (correct answer)
  3. Because Sofia finished her math, she started reading.
  4. Sofia finished her math and started reading she smiled.
Explanation: This choice fixes the run-on by separating the two complete thoughts into two sentences with a period. The first choice only adds a comma, which creates a comma splice instead of fixing the run-on. The third choice adds a cause-and-effect word that was not part of the original meaning. The fourth choice joins the sentences in a confusing way and adds an idea that was not there before.
