How have the Piedmont region's physical features influenced its local economy?

my answer
A. In places, it has rocky soil that is better for manufacturing than farming.***
B. The hilly land makes it difficult to transport goods, which limits economic activity.
C. The lack of rivers in the region limits farming and transportation.
D. The flat land is used for farming rather than auto and textile manufacturing.

You may be right. Read lots to be sure:

To determine how the Piedmont region's physical features have influenced its local economy, you can analyze the characteristics of the region and consider their impact on different economic activities.

One physical feature of the Piedmont region is its rocky soil. This can be significant in influencing the local economy. Rocky soil is generally less suitable for farming, particularly for large-scale agriculture. Instead, it can be more advantageous for manufacturing industries. Factories and industries that require mineral resources, such as mining and quarrying, may thrive in areas with rocky soil. Therefore, option A is the most accurate answer.

On the other hand, options B and C do not accurately reflect the influence of physical features on the local economy. While the hilly land may present challenges in terms of transportation, it does not necessarily limit economic activity overall. Similarly, the lack of rivers may limit farming and transportation to some extent, but it does not necessarily exclude other economic sectors like manufacturing.

Option D is also incorrect. While flat land may be suitable for farming, it does not necessarily mean that auto and textile manufacturing cannot coexist with agriculture in the region.

In summary, the physical feature of rocky soil in the Piedmont region is likely to have influenced the local economy by favoring manufacturing industries over large-scale agriculture.
