For me, this exercise is a "Translate this sentence - Mangiamo un quarto della torta".
And the male audio did say "un quarto", not "una quarto".
You can also click on the word "un" to hear it.
Anyway, at this level, one should be able to write the correct phrase.
My personal favourite is how my not-tuned-to-Italian-comprehension ears heard the audio says "say ye lunica" and I immediately thought to translate that to - "Are you lunatic?!" Heehee
Happy DL e-learning.
Not I. But there's a recurring issue with the speakers on my laptop mangling certain sounds. By the way, how would Italians say "the torte" (https://www.tasteofhome.com/recipes/special-raspberry-torte/)?
