write complete sentences that communicate their meaning clearly and accurately, varying sentence type, structure, and length to suit different purposes and making smooth and logical transitions between ideas (e.g., use a variety of sentence structures, including compoundcomplex sentences; use prepositional and participial phrases and adjectival and adverbial clauses to add details and/or qualifying information; insert rhetorical questions for emphasis in an argumentative essay; insert a sentence fragment to interrupt the flow in a paragraph for effect; use subject-verb inversion to vary sentence rhythm)
