Read an excerpt from the introduction to an informative essay. The Neolithic Revolution was an important turning point in history. Instead of moving from place to place to gather enough food to survive, early peoples were able to settle in one place, farm crops on a large scale, and build settlements. How could a writer most improve the thesis in this introduction?

The thesis says the Neolithic Revolution was an important turning point, but it does not explain why that change mattered over time. The writer could strengthen it by explaining the lasting effects of people settling, farming, and building communities. Choice B, “by explaining the lasting change that occurred,” would make the thesis more specific; details about sources, later events, or particular crops would not directly clarify the revolution’s significance.
