Read and answer to critique an author

After reading Chapter 7, complete exercise "1" at the end of Section 7.4:

Select a piece of writing from a web site, book, newspaper, or magazine. Imagine that you are delivering an evaluation to the author of the piece. Using the strategies in this section, write a tactful and diplomatic critique.

Please note that the instructions in the textbook say the instructor may make this a class exercise, for our class, this will not be a class exercise. You will write your response in the form of a Block Letter and submit it as a regular assignment.
