There is an audio problem in this sentence, that we'll fix as soon as possible. Thanks!
This sentence was built for you to see the difference between singular and plural. Therefore, to split the two parts, Duo has used a comma. I could have been a semi-column or a full stop, or any other sign meant to just make a break between the two parts.
What is the difference in pronunciation between chiens and chiennes?
Try to play this audio example: http://translate.google.com/#fr/en/les%20chiens.%20les%20chiennes.
I can really hear the difference on Google Translate.
I wonder if the Duo robot is so clear.
I could not tell the differences between "chiens sont noirs" and "chiennes sont noires". I hope my ear improves!
maybe try "chien, chienne" on Google/Translate to better hear the difference
because "noir, noire, noirs, noires" is an adjective that is easy to use for grammar purposes. As you can see, all gender and number forms are different.
that is not the case for many other color adjectives.
