Question

we do (guided instruction questions): what does john muir argue is the primary reason people cut down trees? to clear land for farming; to build new homes; because they think the trees are diseased; for fun or a dollar

Explanation:

John Muir, a conservationist, argued that people cut down trees "For fun or a dollar" (for profit or recreational/thoughtless reasons). The other options (clearing for farming, building homes, thinking trees are diseased) don't align with his view on the primary reason; he emphasized economic gain or frivolous motives.

Answer:

D. For fun or a dollar
