Answer: To stay with some well-to-do friends. Hope this helps
First of navigavisti is past tense, so you can immediately rule out options B and C. Then, the phrase <em>de quo </em>can be translated as <em>of who, </em>or <em>of what, </em>or <em>from where. </em>Thus, the correct answer is From where did you sail?
De quo means from where, and not why, so A is also incorrect.
the variable y is a function of the variable x. y is dependent on x
y=f(x) ???
