Determine whether the given set s is a subspace of the vector space v.
a. v = m_3 (r) and s is the set of 3 times 3 matrices with trace 0 (recall the trace of a matrix is the sum of its diagonal entries)
b. v = m_3(r) and s is the set of 3 times 3 matrices of rank 1
c. v = m_3 (r) and s is the set of 3 times 3 matrices a such that the vector (7 4 3) is in the of a
d. v = m_2(r) and s is the set of 2 times 2 matrices a such that a^2 = o (here o is the 2 times 2 zero matrix)
e. v = m_2 (r) and s is the set of 2 times 2 matrices that commute with the matrix (0 5 1 6)
f. v = m_3(r) and s is the set of 3 times 3 matrices a such that a^2 = a

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

when the constitution was formally published 2 years later (1857). it also contained an article which permitted education free from any religious influence, the removal of the catholic church institutional privileges, and the sale of property belonging to the church. all of these provisions were clearly against the catholic church interests.
