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 - either with just a comma (comma splice: 'I ran, she walked') or with no punctuation (fused sentence: 'I ran she walked'). In this example, 'Sofia finished her book she told Chen about it' is a run-on. Two complete sentences ('Sofia finished her book' and 'she told Chen about it') are run together with no punctuation. Choice A is correct because it properly separates the two sentences with a period: 'Sofia finished her book. She told Chen about it.' Choice C represents a comma splice error, which occurs when students think a comma alone can join two complete sentences. 'Sofia finished her book, she told Chen about it' is still a run-on - comma alone doesn't properly join sentences. Run-ons need proper punctuation (period) or conjunction (comma + and/but/so/or) to join. To help students: Teach to read slowly and listen for two complete thoughts running together - if yes, need period or comma+conjunction (and, but, so, or) to join. 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: Comma splice (comma alone between sentences - need period or add conjunction), Fused sentence (no punctuation between sentences). Watch for: using comma alone to join sentences (need comma + conjunction like 'and'), thinking any sentence with comma is correct, and not recognizing when two complete thoughts are present.

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 - common types include missing subject ('Ran to school' - who ran?), missing predicate ('The big dog' - what about the dog?), or dependent clause alone ('Because it rained' - what happened?). In this sentence, 'Ran to the playground after lunch' is a fragment. It is missing a subject - we don't know who ran to the playground. Choice B is correct because it adds the missing subject 'Jamal' to create 'Jamal ran to the playground after lunch,' which now has a subject (Jamal), predicate (ran to the playground after lunch), and expresses a complete thought. Choice D represents a run-on error, which occurs when students try to add too much information by joining two complete sentences with only a comma. 'Jamal ran to the playground after lunch, he played tag' is a comma splice - two complete sentences incorrectly joined with just a comma. To help students: Teach the 'complete sentence test' - (1) Find subject (who/what it's about), (2) Find predicate (what happens - needs verb), (3) Ask 'Does it make sense alone?' If missing any part = fragment. Common fragments include missing subject ('Went to school' - who went?), missing predicate ('The small bird' - what about it?), and dependent clause alone (starts with because/when/if but doesn't tell what happened). Watch for: thinking any long group of words is complete, not recognizing when subject is missing, and overcorrecting by creating run-ons when trying to fix fragments.

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 - either with just a comma (comma splice) or with no punctuation (fused sentence). In this example, 'The bell rang we lined up' is a run-on. Two complete sentences ('The bell rang' and 'we lined up') are run together with no punctuation between them (fused sentence). Choice B is correct because 'The bell rang. We lined up.' properly separates the two sentences with a period, making each a complete sentence that stands alone. Choice A represents a comma splice error, which occurs when students know sentences need separation but use only a comma - commas alone cannot join two complete sentences without a conjunction. To help students: Teach to read slowly and listen for two complete thoughts running together - if yes, need period or comma+conjunction (and, but, so, or) to join. Practice finding where one complete thought ends and another begins by asking 'Could this part stand alone as a sentence?' Common run-ons: Comma splice (comma alone between sentences), Fused sentence (no punctuation between sentences). Watch for: using comma alone to fix run-ons (creates comma splice), not hearing where sentences should separate, thinking any pause needs only a comma.

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 - common types include missing subject ('Ran to school' - who ran?), missing predicate ('The big dog' - what about the dog?), or dependent clause alone ('Because it rained' - what happened?). In this example, 'Ran to the bus stop' is a fragment. It is missing a subject - we don't know who ran to the bus stop. Choice B is correct because it correctly identifies this as a fragment due to the missing subject. Choice A represents a common error where students think any group of words with a verb is complete, but fragments need all three parts: subject, predicate, and complete thought. To help students: Teach the 'complete sentence test' - (1) Find subject (who/what it's about), (2) Find predicate (what happens - needs verb), (3) Ask 'Does it make sense alone?' If missing any part = fragment. Watch for: thinking any sentence with a verb is complete (missing subject is still fragment), not asking 'who' or 'what' did the action to find missing subjects.

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 because, when, if, although but don't tell us what happened. In this example, 'Because it was windy at recess' is a fragment. It is a dependent clause that doesn't express a complete thought - the word 'because' makes us expect to hear what happened as a result of the wind, but that information is missing. Choice C is correct because it correctly identifies this as a fragment - specifically a dependent clause fragment that needs a main clause to complete the thought. Choice B represents a common error where students think any clause with subject and verb is complete, which occurs when students don't recognize that dependent words (because, when, if, although) make thoughts incomplete. 'Because it was windy at recess' has a subject (it) and verb (was), but the word 'because' makes it dependent - it needs completion like 'Because it was windy at recess, we played inside.' To help students: Teach that dependent words (because, when, if, although, since) create incomplete thoughts that need main clauses. Practice completing dependent clauses - 'Because it rained...' needs 'we stayed inside' or similar. Common fragments include dependent clause alone (starts with because/when/if but doesn't tell what happened). Watch for: not recognizing dependent words make incomplete thoughts, thinking any group with subject+verb is complete, and confusing dependent clauses that sound natural in speech with complete sentences in writing.

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). In this example, 'Yuki read a book and wrote a summary' needs to be analyzed for completeness. This sentence has a subject 'Yuki' and a compound predicate 'read a book and wrote a summary' (two actions connected by 'and'), and it expresses a complete thought. Choice C is correct because this is a complete sentence - it has all required parts and is properly constructed with one subject doing two actions joined by the conjunction 'and.' Choice B represents a common error where students confuse compound predicates with run-ons, which occurs when students think any sentence with 'and' is a run-on. 'Yuki read a book and wrote a summary' is NOT a run-on because it's one subject (Yuki) doing two things, not two complete sentences joined together. A run-on would be 'Yuki read a book she wrote a summary' (no punctuation) or 'Yuki read a book, she wrote a summary' (comma splice). To help students: Teach the difference between compound predicates (one subject, two actions: 'She ran and jumped') and run-ons (two complete sentences incorrectly joined: 'She ran, he jumped'). Practice identifying: Is there one subject doing multiple things (compound predicate = complete sentence) or multiple subjects with their own actions (potential run-on if not properly joined)? Watch for: thinking any sentence with 'and' is a run-on, not recognizing compound predicates as complete sentences, and confusing length or complexity with run-on status.

In this example, 'Sofia finished her math she started reading' is a run-on. Two complete sentences 'Sofia finished her math' and 'she started reading' are run together with no punctuation, creating a fused sentence. Choice B is correct because it properly separates the two sentences with a period: 'Sofia finished her math. She started reading.' Choice A represents a comma splice, which occurs when students join sentences with only a comma.

If missing any part = fragment. For run-ons, teach to read slowly and listen for two complete thoughts running together - if yes, need period or comma+conjunction (and, but, so, or) to join. Practice identifying subjects and predicates in sentences. Common fragments: Missing subject ('Went to school' - who went?), Missing predicate ('The small bird' - what about it?), Dependent clause alone (starts with because/when/if but doesn't tell what happened). Common run-ons: Comma splice (comma alone between sentences - need period or add conjunction), Fused sentence (no punctuation between sentences). Watch for: thinking 'The big brown dog' is complete (missing predicate/verb), thinking any long group of words is complete sentence, using comma alone to join sentences (need comma + conjunction like 'and'), not recognizing dependent words (because, when, if, although) make incomplete thoughts that need main clause. Teach correction strategies: Fragments - add what's missing; Run-ons - separate with period OR join with comma+conjunction OR use dependent word.

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?'

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 subject ('Ran to school' - who ran?), missing predicate ('The big dog' - what about the dog?), or dependent clause alone. In this fragment, 'Is my favorite game' is missing a subject - we don't know what is the favorite game. Choice A is correct because it identifies that a subject (who or what) is missing from this fragment. The fragment has a predicate 'is my favorite game' but no subject to tell us what thing is the favorite game. Choice B represents a common misconception where students think fragments need punctuation fixes, which occurs when students confuse fragment problems with punctuation problems. Adding a comma won't help 'Is my favorite game' - it needs a subject like 'Chess is my favorite game' or 'Soccer is my favorite game.' Fragments are fixed by adding missing parts (subject, predicate, or completion), not by adding punctuation. To help students: Teach the 'complete sentence test' - (1) Find subject (who/what it's about), (2) Find predicate (what happens - needs verb), (3) Ask 'Does it make sense alone?' For this fragment, step 1 fails - no subject found. Common fragments include missing subject ('Went to school' - who went?), and these often start with a verb. Watch for: thinking punctuation fixes fragments, not recognizing when subject is missing especially when sentence starts with verb, and confusing different types of sentence errors (fragments need missing parts, not punctuation).
