Example Input: The Canada Act 1982 (1982 c. 11) is an Act of the Parliament of the United Kingdom that was passed (as stated in the preamble) at the request of the Parliament of Canada, to 'patriate' Canada's constitution, ending the necessity for the British parliament to be involved in making changes to the Constitution of Canada. The Act also formally ended the 'request and consent' provisions of the Statute of Westminster 1931 in relation to Canada, whereby the British parliament had a general power to pass laws extending to Canada at its own request.

Example Input: A callus is an area of thickened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on feet because of frequent walking and incorrectly fitting footwear. While they can be perceived as being unsightly, calluses are generally not harmful, but if neglected for long periods may sometimes lead to other problems, such as a skin ulceration or infection, or cause the sufferer to try and offload the affected painful area, which can place excessive stress on the asymptomatic side. Rubbing that is too frequent or forceful will cause blisters as opposed to calluses to form.
Example Output: why do i have callus on my hands
