This is your code. >>> a = [5, 10, 15]
>>> b = [2, 4, 6]
>>> C = [11, 33, 55]
>>> d = [a, b, c]

d[2][0] is ___?

11

Explanation:

the second in the d aray is c because to call the first value, it is d[0]. So, to call c, you put d[2]. And the 0 of the c array, or the 0 of the 2 of the d array, it is 11

put it in a program. I use JS so if you have an Apple, open script editor and change the script from AppleScript to JavaScript and put in this code:

var a = [5, 10, 15];

var b = [2, 4, 6];

var C = [11, 33, 55];

var d = [a, b, C];

d[2][0];
