Test 1 Errata

Question #29:

* A comment in the code block of the remove_duplicates() function is wrong:
* As written: "Loop through items in a_list. If item not in *a_list* then append it to new_list"
* Should be: "Loop through items in a_list. If item not in *new_list* then append it to new_list"
