Final answer:
The evaluation lacks a summary of the claim, evaluation of the evidence, and a concluding statement, which are necessary to tie back to the thesis and provide a sense of completeness.
Step-by-step explanation:
The element missing from this evaluation could be identified as b. A summary of the claim, which is crucial in understanding the intention of the writer and the argument being made. Additionally, c. An evaluation of the evidence might also be lacking, as there is insufficient support with credible evidence mentioned. Lastly, d. A concluding statement seems to be another missing part since this is necessary to tie back to the thesis and provide a sense of completeness to the argument.
In an effective evaluation, it is critical that the writer establishes a clear thesis, provides a summary of the claim, evaluates the evidence, and concludes with a statement that reinforces the thesis and leaves the reader with a final thought or impression.
