Sorry, but this is wrong.
Ignoring the fact that you've used an array slice to get a single value from an array (@ra[$_]), which I'll assume is just a typographical error, your use of 0..@sub to iterate over the indices1 of the array won't work. @array returns the number of values in the array, so your code iterates over the arrays from indicies 0 to 4, or five elements. The arrays only have four elements each.
To fix it, you could try something like 0 .. $#sub.
Two other points:
- You're missing a space in $_right.
- You telling the user they've got question 0 correct, when most people would expect that to be question 1.
Obfu'd code is ok, but obfu'd code that doesn't work seems a bit pointless to me

Is this going out live?
No, Homer, very few cartoons are broadcast live - it's a terrible strain on the animator's wrist
1: Is it indices or indexes? - I can never remember
