I am somewhat at a loss about 2 of the sentences of "practice and review" in chapter 17, and I hope someone will be able to shed the light
1. Potens quoque est vis artium, quae nos semper alunt
The able is force of arts, which not always provide support? Doesn't really make sense. What am I missing?
3. Nam illa aetate pars populi in Italia iura civium numquam tenuit.
For during that era (?) part of the people in Italia never posessed [any] civil rights. How do I conciliate the 'never' and the 'during that time'? Shouldn't it be something like 'before this time'?
