This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'after' is a subordinating conjunction that shows time. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: school ends and Marcus rides his bike. The relationship between them is time. We need a conjunction that shows this relationship specifically. Choice B is correct because 'after' properly shows the later time. Before/After: sequence (before we eat / after school). This makes the sentence logical and clear. Choice A is incorrect because it shows cause. Using 'because' would mean riding because school ended, not after. Students confuse these when they think all conjunctions are interchangeable. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach FANBOYS for coordinating (For And Nor But Or Yet So) and common subordinating (because when if before after). Practice: I like X ____ Y (and). I wanted X ____ Y happened (but). I did X ____ Y was true (because). Watch for: using and for everything / not recognizing cause-effect needs because or so / confusing time words (before/after/when).

This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'before' is a subordinating conjunction that shows time. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: we eat lunch and we wash our hands. The relationship between them is time. We need a conjunction that shows this relationship specifically. Choice B is correct because 'before' properly shows the earlier time. Before/After: sequence (before we eat / after school). This makes the sentence logical and clear. Choice A is incorrect because it shows later time. Using 'after' would mean washing hands after eating, reversing the sequence. Students confuse these when they don't identify the relationship between ideas. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach FANBOYS for coordinating (For And Nor But Or Yet So) and common subordinating (because when if before after). Practice: I like X ____ Y (and). I wanted X ____ Y happened (but).

Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Jamal wanted to play and it started raining. The relationship between them is contrast. We need a conjunction that shows this relationship specifically. Choice C is correct because 'but' properly shows the contrast. But shows contrast between two different ideas. This makes the sentence logical and clear. Choice A is incorrect because it shows addition. Using 'and' would mean adding ideas without contrast, like both happening together positively. Students confuse these when they don't identify the relationship between ideas. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if.

In this sentence we have two ideas: Maya wore boots and the ground was wet. The relationship between them is cause. We need a conjunction that shows this relationship specifically. Choice A is correct because 'because' properly shows the cause. Because explains the reason why. This makes the sentence logical and clear. Choice D is incorrect because it shows contrast. Using 'but' would mean opposing ideas, like wearing boots despite dry ground. Students confuse these when they think all conjunctions are interchangeable. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if.

Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: the bell rings and we line up quietly. The relationship between them is time. We need a conjunction that shows this relationship specifically. Choice B is correct because 'when' properly shows the time. When shows the time relationship. This makes the sentence logical and clear. Choice A is incorrect because it shows condition.
