Translation:They eat a lot of fish and rice in Japan.
Also, I would love a discussion on "beaucoup de poisson" vs. "beaucoup de poissons". If I recall correctly, the latter means "a lot of different kinds of fish" while the former means "a lot of fish". The former should still be correct (and is indistinguishable in audio) unless "poisson" limits us to a lot of a single type of fish, versus a lot of fish (variety unspecified).
I stopped bothering with the speaking test a long time ago, as I have a teacher and I'm in France, so I know how my pronunciation is going and when it's good & bad. I found the speaking exercises pretty unhelpful. There must be a better program with feedback for speaking.... somewhere
