Under “nous avons pu réinvestir les dons qui nous étaient parvenus”, the “voix passive” lesson is listed beneath it, and not the “plus que parfait” lesson.
But isn’t it that case that this line is an example of plus que parfait, and not of voix passive?
This may seem like splitting hairs, but I find the listed lessons very useful even just from their titles, to guide my understanding of the grammar.
