linear algebra?

Question

let V be a vector space and let A be any subset V. there exists linear subspaces of V that contain A (for instance, V itself is such a subspace) let n = (N: N is a linear subspace of V containing A) show that n contains a smallest element. (try intersection of n) thus, there exists a smallest linear subspace of V containing A
