A real-world geographic situation described only in words, followed by seven short parts (A–G) that ask you to identify, define, describe or explain ideas from at least two units. On the exam: Question 1 of 3 in the 1-hour-15-minute free-response section (Section II). The three questions together are 50% of your exam score, so each is worth about 16.7%; 7 points, one for each part A–G. College Board suggests about 25 minutes per question, including up to 5 minutes to plan. No calculator.
The question
In 1826, Johann Heinrich von Thünen published a model of agricultural land use around a single market town. Today, many metropolitan areas in the United States are surrounded by farmland that is under pressure from suburban growth. Answer all seven parts, (a) through (g). Write in complete sentences; a list of terms will not earn points.
