Generate 5 SAT-style grammar questions targeting the Drop the Fat strategy. Make them medium-to-hard Digital SAT difficulty. Use realistic SAT passage contexts (science, history, social science, literature). Each passage should be 2-4 sentences long with the tested sentence embedded naturally within the paragraph. Vary the answer choices and grammatical structures. Do not repeatedly use simple subject-verb agreement patterns such as remains/remain, shows/show, contains/contain. Include different verb forms, passive constructions, collective nouns, intervening phrases, appositives, prepositional phrases, and modifier distractions. Make the questions feel like official SAT items rather than worksheets.
