The answer key is every correct pairing in this topic. Use it to check the data before a topic is published — a wrong pairing here teaches a child something false. The Spanish noises especially: guau, miau, muu, cuac and quiquiriquí are certain, but jiiii (horse), cloc cloc (hen), mee (goat), iii-aah (donkey) and onc onc (goose) are best checked by somebody who grew up with them — they vary by country and I am not confident in them. Worth a second pair of eyes on the Spanish column, and on the noises: they are the English spellings, and Spanish writes several of them differently — a cow says “mu” and a dog “guau”, which is a category this topic could grow rather than a mistake to fix in place.
