Answer :
A CONTENTIOUS person likes to argue about everything. "My mom seems to be CONTENTIOUS person so I avoid conflict with her". Theres a couple ways to use TENSION. "There was a lot of TENSION between the two boys". Or tension used as emotional or physical pain, "I have a TENSION headache so I cannot concentrate well". Both in a sentence could be…."My mom and I are both CONTENTIOUS, it really puts TENSION on our relationship".
