What are some difficulties that could arise for a married couple that practices two different religions?

Having a lack of respect for each other's heritage. Not being curious about your partner's heritage, culture or religious beliefs. Failing to timely inform your families and friends of your holiday decisions. Forcing your children to feel as if they must choose between their father's or mother's religion.

Hope this helps :)

b. parliament was weaker than the monarchy.

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
