An outline for a Panel Discussion program is a brief, chronological listing of the program's progression.

Explanation:

Panel discussion is brief:

        It is not a set of presentations, rather the panel format allows only brief introduction and then discussion among audience and panelists.

Chronological order:

         Discussion is done in chronological order, which means events are discussed with time as they occur.

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.
