Why is blue the second element and not the first?

I am a little confused. I know that position one in an array is "0" even though it is zero, would it still be referred to as the first element?

I kept choosing the answer Green because I start at zero and then Blue in my mind is the first element [ 1 ] then Green [ 2 ]. I think im getting the numbers and the verbage mixed up

Hey Arvelle,

you are right that in the world of programming, counting starts with the number 0, and that can indeed get confusing. However, the question asks which is the "second" element - don't confuse that with the element at position 2. In our every-day language we still say "first, second, third"; this also applies in programming. (Imagine if you'd say "zero-th", hehe).

So the first element is the element at position 0 ("Red"). The second element is the element at position 1 ("Blue"), etc.

Hope that helps.
