Answer: is expanding
Explanation:
A supernova is a stellar explosion that occurs as a result of the final stage of a star's life. This event can be very remarkable, even observable to the naked eye. This means that supernovae are characterized by very intense flashes of light that can last from several weeks to several months. In addition, its luminous intensity increases rapidly until it reaches an absolute magnitude greater than the rest of the galaxy, and then gradually loses its brightness until it disappears completely.
Then, a supernova is a very bright element, however, as its distance from the observer is greater, they will be less luminous (look fainter). This is presented as proof that we live in <u>a universe that is expanding</u> and is not flat.

B. canadian territories are under a constitutional monarchy
Canada
still exists such that the Queen of England is the head of state or
formal representative of canada. However they are protected by a
constitution and act as an independent nation with a head of government
(the prime minister) taking care of actual governmental affairs. The
queen does not have direct power in the same manner as the prime
minister hence the division head of state vs head of government.
