The second response is the best option for completing the R.A.C.E. strategy, as it clearly follows the structure:
- Restate: It restates the question by referencing the utility of etymology for readers.
- Answer: It provides a direct answer about how etymology helps understand the meaning of words.
- Cite Evidence: It includes evidence about how understanding history helps in identifying patterns and definitions of unfamiliar words.
- Explain Evidence: It explains that this knowledge can be applied to other words, enhancing vocabulary and comprehension.
In contrast, the other responses are less structured, with some lacking the necessary elaboration and application to other words. Therefore, the second response serves the prompt most effectively.
