Answer: This feedback is for a small-scale revision.
Explanation: A thesis statement is an introduction of an essay that contains the main topic of it, commonly resumed in one or two sentences. A small-scale revision focuses on questioning the grammar structure, spelling, and word choice. Therefore, since it is a thesis statement, the writer must rewrite it and make sure that the main idea is conveyed clearly in the sentence, using the correct words and summarizing a whole topic.
