Why are multiple NAND gates used to replace other single function gates? Select one: a. NAND gates are packaged more densely on IC's than other types of gates. b. It is easier to design logic circuits with a single gate type, since you only have to fully understand how one type of gate works. c. NAND gates are cheaper than any other type of gate. d. It makes it possible to use spare portions of NAND IC packages to implement other logic functions, perhaps reducing the total IC package count.

browsing like internet search? don't look at anything stupid. or set up restrictions on ur device's search engine. and if something suspicious comes up don't be dumb and click on it. i hope that's what ur question meant.

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.
