This task is about translating a given English language sentence to French.

You'll see there, if you look at the music again (it's really important to see the music) that the first note, the 3 (this is the 3rd fret of the 5th string) is played with the thumb on the 5th string by itself, and then on beat 2, our thumb has moved over to the 4th string and we're using our 2nd finger to play the 2nd string.
Vous verrez si vous regardez la partition la 1ère note, le 3 (3ème frette de la 5ème corde) est jouée par le pouce sur la 5ème corde toute seule, et sur le 2ème temps, le pouce passe sur la 4ème corde. et on prend le 2ème doigt pour jouer la 2ème corde.
