Explanation
Correct answer: B.
Choice B is the best answer. It best states the main idea of the text. The text opens with the statement that Taylor uses local plants and vegetables to dye wool. The rest of the text describes how she does this.
Why the other choices are wrong
Choice A
Choice A is incorrect. This doesn’t state the main idea of the text. The text only mentions one rug: In the Path of the Four Seasons, in which reds and browns are featured. It never mentions whether or not these colors are featured in her other rugs.
Choice C
Choice C is incorrect. This doesn’t state the main idea of the text. The text never says that Taylor finds it difficult to locate Arizona dock roots.
Choice D
Choice D is incorrect. This doesn’t state the main idea of the text. The text never says that In the Path of the Four Seasons is widely acclaimed. Rather, it discusses the rug to illustrate the point made earlier in the passage: that Taylor uses local plants and vegetables to dye wool.
