Explanation

This tests CCSS.L.2.1.f (producing, expanding, and rearranging complete simple and compound sentences). A simple sentence has one complete thought ("The dog barked"). A compound sentence joins two complete thoughts with a coordinating conjunction: and (adds information), but (shows contrast), or (shows choice), or so (shows result). When combining two sentences into a compound sentence, put a comma before the conjunction: "The dog barked, and the cat ran." Expanding a sentence means adding descriptive details: add adjectives to describe nouns ("The little boy"), add adverbs to tell how ("walked slowly"), or add phrases to tell when/where ("after school," "at the park"). Both parts of a compound sentence must be complete sentences that could stand alone. Choice A is correct because it combines two complete sentences with the appropriate conjunction 'but' and a comma, showing contrast between running outside and the rain starting. Choice B shows a missing comma before the conjunction, which second graders often forget in compound sentences. To help students: Teach coordinating conjunctions (and, but, or, so) and practice combining sentences by deciding the relationship and using comma + conjunction. Use the check: Cover one side of the conjunction—is it complete? Cover the other—is it complete?
