I want to know the answer to the following question:
Which political division does not often utilize its power, if it has any?
All the background I'm provided with is that "In parliamentary systems, governments are generally required to have the confidence of the lower house of parliament (though a small minority of parliaments, by giving a right to block supply to upper houses, in effect make the cabinet responsible to both houses, though in reality upper houses, even when they have the power, rarely exercise it).". Is that enough to answer the question?
Answer: yes
