Alright for (i) I think I got it.
(i) Span not equal means x is not a linear combi of v and w. We know x is redundant, so it must be a linear combi involving u, meaning the statement is true
(ii) For this I gather y is non-zero and not a linear combi of u v w x. I'm not sure if the new set can be expressed as a
linear span if y is a fixed vector.
