The day of the summer solstice, normally reckoned as June 21.
True
24 hours
There is one of these 'rings' around the north pole ... called the Arctic Circle ... and another one around the south pole ... called the Antarctic Circle. These circles mark the farthest distance from each pole that can possibly have 24 hours without a sunrise, and 24 hours without a sunset. Each of them is located 23.5 degrees (of latitude) away from its pole. On June 21, the sun doesn't set on the Arctic Circle (the north one), and doesn't rise on the Antarctic Circle (the south one). On December 21, there's no sunrise on the Arctic Circle, and no sunset on the Antarctic Circle.
The Tropic of Cancer is to the Tropic of Capricorn as the Arctic Circle is to the Antarctic Circle. They are lines of latitude either north (Arctic Circle, Tropic of Cancer) or south of the equator.
Anyplace on earth that's farther north than the Arctic Circle, or farther south than the Antarctic Circle, has at least one day a year when the sun doesn't rise, and at least one day a year when the sun doesn't set. The closer you get to the poles, the longer these annual periods of no sunrise and no sunset get. Most of Alaska is south of the Arctic Circle, and has a sunrise and sunset every day of the year. The Arctic Circle crosses Alaska on the line roughly through Shishmaref, Allakaket, and Fort Yukon. North of that line is where you can have 24 hours without a sunrise or 24 hours without a sunset.
Everywhere north of the Arctic Circle and south of the Antarctic Circle has at least one day per year on which the sun does not set. The closer you get to the poles, the more days without a sunset there are. Six months later, those places have multiple consecutive days on which the sun never rises.
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the June solstice and December solsticerespectively).
You are misinformed, the Sun DOES set in the Arctic Circle.
Your answer depends on where you are on the continent. On the Antarctic Peninsula -- near the Antarctic Circle, you only experience one day of no sunset. At the South Pole, the period is six months.
The answer depends on a winter day in which part of the world! 10 deg C would be absurdly warm in the Arctic circle but exceptionally cold in the Tropics!
Anywhere in the polar regions; north of the Arctic Circle, or south of the Antarctic Circle. The duration of the continual daylight or night depends on how far across the circle you are. If you lived just north of the Arctic Circle, there might be a two-or-three day period around December 21 when the Sun would not-quite-rise, and a couple of days around June 21 when the Sun would not quite set. At the poles, the Sun comes up at the spring equinox and goes down at the fall equinox; one "day" that lasts a year.

The north of Finland is above the Arctic Circle so the sun doesn't set there for a period in the summer. In the south of Finland, the sun will set but is barely goes below the horizon, meaning that it never gets truly dark.
That depends on your latitude. The Arctic is all of the area north of the Arctic Circle, which is 66.56° north latitude. At the Arctic Circle, the sun sets every day, although on the June solstice it just barely sets then immediately rises again as soon as it sets. The farther north you go in the Arctic, the fewer the annual number of sunsets (and sunrises). At the northernmost point, the north pole, the sun rises once a year and sets once a year.
Anyplace on earth that's farther north than the Arctic Circle, or farther south than the Antarctic Circle, has at least one day a year when the sun doesn't rise, and at least one day a year when the sun doesn't set.

The sun does not set at all north of the Arctic Circle on the day of the June solstice.
The Sun can rise, and immediately set, in the South only on December 21, and only in places along the Arctic Circle.
