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 because. Choice B is correct because it has an independent clause 'we stayed inside to read books' and a dependent clause 'Because it was raining' that cannot stand alone. Choice A is incorrect because it uses coordinating conjunction 'so' to join 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). Watch for: thinking compound predicates with compound sentences (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. 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 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. For this compound sentence we need two complete thoughts joined by a conjunction like and with a comma. Choice B is correct because it has two independent clauses joined by 'and' with a comma: 'Keisha packed her lunch' and 'she drank water,' both of which can stand alone. Choice A is incorrect because it misidentifies the sentence as simple, but there are two clauses; students confuse compound sentences with simple ones that have compound predicates. 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 compound sentence we need two complete thoughts joined by a conjunction like so with a comma before it. Choice A is correct because it has two independent clauses joined by 'so' with a comma: 'It was sunny' and 'we went to the park,' both of which can stand alone. Choice B is incorrect because it lacks the comma before 'so,' making it a run-on; students confuse proper punctuation in 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.

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 this complex sentence we need one complete thought and one incomplete clause with a subordinating conjunction like when. Choice C is correct because it has an independent clause 'we line up' and a dependent clause 'When the bell rings' that cannot stand alone. Choice D is incorrect because the full sentence is not a fragment, though students might think the dependent clause alone is a fragment; students confuse fragments 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.).
