BONUS QUESTION: Given questions #1-10 above, select three statements you identified as “false” and re-write them to make them “true”. As you select a statement to re-write for bonus point consideration, be sure to write the original question number (Example: “I am re-writing question #7” or simply “#7”). If you do not do this, 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 statement to simply include “not” or “don’t” (etc) is not properly re-writing a statement and shall not be accepted. Further, when re-writing your false statements, the modified true statements should pertain directly to course materials, only. Finally, if you re-write more than three statements, only the first three statements will be graded for bonus point consideration (even if an error is made in re-writing one of the first three statements and a later statement has been re-written properly).
