Given questions #1-12 above, select four statements you correctly identified as “false” and re-write them to make them “true”. As you select a statement to re-write, be sure to write the original question number (Example: “I am re-writing question #7” or simply “#7”). If you do not properly reference your response as instructed, then no points shall be awarded. When re-writing your false statements, keep each statement to one sentence. You should be able to modify a false statement to make it true by changing just a word or two. Changing a false statement to simply include “not” or “don’t” (etc) is not properly re-writing a false statement and shall not be accepted. Further, when re-writing your false statements, the modified true statement should pertain directly to course materials only. If you re-write more than four statements, only the first four statements will be graded (even if an error is made in re-writing one of the first four statements and a later statement has been re-written properly).
