One subtask in the game is to roll the dice. explain why is roll the dice an abstraction.

A game is built from a combination of sub-tasks in order to provide the best experience to the user and make sure that the interface is comprises of only the results of the ongoing sub-tasks to provide a higher degree of data abstraction.

Data abstraction refers to the process of representing the essential information without including the background details. Rolling a dice is preferred to be a sub-task so that the user only gets to know about the result of the roll and does not have to wait for or anticipate the result. Moreover, a game may consist of n number of sub-tasks so it is not a good idea to include them in the main framework and are preferred to be abstracted.

i believe the answer would be b. within an intersection or on a crosswalk. hope this ! : )

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
