I still don't understand why they have you do something and then give you the same thing in the next problem

who lives in a pineapple under the sea

When you hear this woman talk you don't hear 'una'! You hear 'un'

[Kama410]

Yeah, I have a tendency to type in exactly what I hear, and it's really tough to hear the end of, "una," and the beginning of, "esponja," as two separate sounds. I get lots of questions wrong because, even though I know the correct answer, I type what I heard...

[tothadam06]

In such cases when grammar dictates it differently it's better to write the version you think is correct, especially since you know that the difference is hard to hear.
In this case, you know that the un/una indefinite article needs to be conjugated to the gender of the noun, "un esponja" can't possibly be correct. It has to be "una esponja".
I occasionally make mistakes with this approach as well when I completely mishear things, but it is a lot less often this way, and it also helps with remembering the rules if you think about the grammar a couple more times.
