Dan wants to check the layout of his web page content. What is the best way in which he can do this?

A. check the page on a smartphone

B. check a paper printout of the page

C. check the page in an old version of a web browser

D. check the page in safe mode

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.
