Write a select statement that returns three columns from the vendors table: vendor_name, vendor_contact_last_name, and vendor_contact_first_name. then, run this statement to make sure it works correctly. add an order by clause to this statement that sorts the result set by last name and then first name, both in ascending sequence. then, run this statement again to make sure it works correctly. this is a good way to build and test a statement, one clause at a time.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
