(See the best response by .screw.)
Code:
var
    list
        SixOne=list("25","3.5","Flash","Magnetic","Read/Write Head","Actuator","Head","4","Hybrid","ReadyDrive","MBR","512","OS","NTFS")

mob
    verb
        SixOne()
            set name = "Hard Drives: Inside A Hard Drive"
            src.ri=0
            var/n = 1
            var/a = input("What is the size of a laptop hard drive?") as text
            if(a == SixOne[n])
                usr<<"You got it right!"
                ri++
            else
                usr<<"Wrong. The answer is [SixOne[n]]"


Problem description:
I get this:
runtime error: cannot read from list
proc name: Hard Drives: Inside A Hard Drive (/mob/verb/SixOne)
source file: Hard Drives - Inside A Hard Drive.dm,12
usr: Ganing (/mob)
src: Ganing (/mob)
call stack:
Ganing (/mob): Hard Drives: Inside A Hard Drive()

All I can say is I have no idea what is going on. I don't know why it's doing this. I must be over-complicating it because I'm not seeing what's wrong.

It's not giving me a error.

That verb should run fine. I did a quick test and no errors occurred:
var/list/SixOne = list("25", "3.5")

mob/verb
    SixOne()
        var/a = input("Say 25...") as text
        if(a == SixOne[1]) world << "SI"

Had 2 same named variables. One was located in a var/ and the other in mob/var/.
