I think this returns an array with one element (the "dog"), but I wouldn't expect the result to be an array.

Oops. I was wrong. Ignore that ^
Completely different nitpick: reject and != are both "negative" in a sense, making this a double negative in my opinion. Can this be rephrased positively?

This totally works and [] has great flexibility. input.first(2) would be clearer to the next reader, though.
…t method, but the instructions say that we can only use each method once. But now I realized I used the reject method twice anyways so it doesn't matter
