1. Let a,b,c,d be row vectors and form the matrix A whose rows are a,b,c,d. If by a sequence of row operations applied to A we reach a matrix whose last row is 0 (all entries are 0) then:        a. a,b,c,d are linearly dependent   b. one of a,b,c,d must be 0.       c. {a,b,c,d} is linearly independent.       d. {a,b,c,d} is a basis. 2. Suppose a, b, c, d are vectors in R4 . Then they form a...
