The best response that completes the R.A.C.E. strategy for the prompt about the text structure of the paragraph is:
The text structure of this paragraph would be classified as cause and effect. For example, the text states that the rising cost of gas has had a "ripple effect on the economy," forcing businesses to charge customers more. This puts great pressure on all parties involved as businesses are unable to sell as many products and services.
This response correctly restates the question (the text structure of the paragraph), provides a direct answer (cause and effect), cites specific evidence from the text (the reference to the "ripple effect" and its consequences), and explains how that evidence supports the classification (the impact on businesses and consumers).
