Answer:
if its a test try to just do it on your own ,you got nothing to lose from a test, its just to understand what you know on the concepts, but if you would still like answers just search around the net or here and you can always post the questions to ask people for help someone would eventually answer your questions but then beware of bots that post links as answer!
Explanation:
When querying a list or table, the use of wildcard symbols maybe used to optimize the search result. The words D*n will return First names which <em>starts with D and ends with n.</em>
