Answer:
C). Rearrange the types of snow so they match the order they’re discussed in the essay.
Step-by-step explanation:
The Thesis statement primarily aims to offer a brief summary of the key claim or argument of the essay or paper. Thus, Gracie can improve her thesis statement by 'reordering the kinds of snow in the same order as it is going to be discussed in the essay' as this will help in guiding the reader about the content that they can expect from her essay. Her introductory paragraph is quite strong as the topic sentence and the outline sentence she offers are sufficient to grab readers' attention and detail them about the main points of the essay and this improvement in the thesis statement will make it perfect and leave the desired impact. Hence, option C is the correct answer.
