This question tests producing simple, compound, and complex sentences (CCSS.L.3.1.i). The sentence is a compound sentence. A simple sentence has one independent clause (one complete thought). A compound sentence has two independent clauses joined by a coordinating conjunction (and/but/or/so) with a comma. A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. The given sentence has two independent clauses joined by 'and' with a comma: 'Yuki packed her lunch' and 'she rode the bus'. Choice C is correct because it identifies the sentence as compound since both parts can stand alone. Choice A is incorrect because it labels it as simple, but there are two clauses so it's compound not simple. Students confuse compound predicates with compound sentences. To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.). Complex = complete + incomplete starting with because/when/if (Because it rained, we stayed inside.). Test by splitting: Can you break it into two complete sentences? Yes = compound. Does part start with because/when/if and can't stand alone? Yes = complex. Practice identifying independent clauses (can stand alone) vs dependent clauses (cannot stand alone). Watch for: thinking compound predicate is compound sentence (I play soccer and basketball is simple) / forgetting comma in compound / creating run-ons or fragments.

This question tests producing simple, compound, and complex sentences (CCSS.L.3.1.i). The question asks students to produce a complex sentence. A simple sentence has one independent clause (one complete thought). A compound sentence has two independent clauses joined by a coordinating conjunction (and/but/or/so) with a comma. A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. For a complex sentence we need one complete thought and one incomplete clause with a subordinating conjunction like if. Choice A is correct because it has an independent clause 'we will play outside' and a dependent clause 'If it is sunny' that cannot stand alone. Choice B is incorrect because it uses a coordinating conjunction 'and' to join two independent clauses, making it compound not complex; students confuse coordinating and subordinating conjunctions. To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.). Complex = complete + incomplete starting with because/when/if (Because it rained, we stayed inside.). Test by splitting: Can you break it into two complete sentences? Yes = compound. Does part start with because/when/if and can't stand alone? Yes = complex. Practice identifying independent clauses (can stand alone) vs dependent clauses (cannot stand alone).

This question tests producing simple, compound, and complex sentences (CCSS.L.3.1.i). The question asks students to produce a simple sentence. A simple sentence has one independent clause (one complete thought). A compound sentence has two independent clauses joined by a coordinating conjunction (and/but/or/so) with a comma. A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. For a simple sentence we need one complete thought, which can include phrases but not additional clauses. Choice C is correct because it has one independent clause 'We wash our hands' with a prepositional phrase 'before lunch' that does not add a dependent clause. Choice B is incorrect because it has two independent clauses joined by 'and,' making it compound not simple; students confuse compound sentences with simple ones that have compound verbs. To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.). Complex = complete + incomplete starting with because/when/if (Because it rained, we stayed inside.). Test by splitting: Can you break it into two complete sentences? Yes = compound.

This question tests producing simple compound and complex sentences (CCSS.L.3.1.i). The question asks students to identify a simple sentence. A simple sentence has one independent clause (one complete thought). A compound sentence has two independent clauses joined by a coordinating conjunction (and/but/or/so) with a comma. A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. For a simple sentence we need one complete thought. We need to find the sentence with only one independent clause about weather. Choice C is correct because it has one independent clause only. 'It is cold and windy today' is one complete thought with a compound predicate (cold and windy), not two separate clauses. Choice A is incorrect because it has two clauses so it's compound not simple. 'It is cold' and 'we wear coats' are two complete thoughts joined by 'so'. Students confuse compound predicates with compound sentences. To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.). Complex = complete + incomplete starting with because/when/if (Because it rained, we stayed inside.). Practice identifying independent clauses (can stand alone) vs dependent clauses (cannot stand alone). Watch for: thinking compound predicate is compound sentence (I play soccer and basketball is simple) / forgetting comma in compound / creating run-ons or fragments.

This question tests producing simple, compound, and complex sentences (CCSS.L.3.1.i). The question asks students to produce a simple sentence with one clause about daily routines. A simple sentence has one independent clause (one complete thought). A compound sentence has two independent clauses joined by a coordinating conjunction (and/but/or/so) with a comma. A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. For a simple sentence we need one complete thought, which can include a compound predicate but still one clause. Choice C is correct because it has one independent clause 'We wash our hands and eat lunch,' where 'wash... and eat' is a compound predicate in a simple sentence. Choice B is incorrect because it has two clauses joined by 'and' so it's compound not simple. Students confuse compound predicates with compound sentences. To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.). Complex = complete + incomplete starting with because/when/if (Because it rained, we stayed inside.). Test by splitting: Can you break it into two complete sentences? Yes = compound. Does part start with because/when/if and can't stand alone? Yes = complex. Practice identifying independent clauses (can stand alone) vs dependent clauses (cannot stand alone).

A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. For a complex sentence we need one complete thought and one incomplete clause with a subordinating conjunction like when. Choice A is correct because it has an independent clause 'he read a funny book' and a dependent clause 'When Chen got home' that cannot stand alone. Choice C is incorrect because it has one clause with a compound predicate, making it simple not complex; students confuse compound predicates with complex sentences. To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.).

A complex sentence has one independent clause and one dependent clause (starting with because/when/if/before/after) that cannot stand alone. For a compound sentence we need two complete thoughts joined by conjunction. The question specifically asks for a compound sentence using 'and' with a comma. Choice C is correct because it has two independent clauses joined by 'and'. 'The students read books' can stand alone, and 'the teacher helped them' can stand alone, making it compound. Choice A is incorrect because it uses 'because' which creates a complex sentence, not compound. Students confuse subordinating conjunctions (because) with coordinating conjunctions (and). To help students: Teach the three types with clear examples. Simple = one complete thought (The dog barks.). Compound = two complete thoughts + and/but/or/so (I like cats, and I like dogs.). Complex = complete + incomplete starting with because/when/if (Because it rained, we stayed inside.). Test by splitting: Can you break it into two complete sentences? Yes = compound.
