Q: Father's Day is a celebration honoring fathers and celebrating fatherhood, paternal bonds, and the influence of fathers in society. In Catholic Europe, it has been celebrated on March 19 (St. Joseph's Day) since the Middle Ages. This celebration was brought by the Spanish and Portuguese to Latin America, where March 19 is often still used for it, though many countries in Europe and the Americas have adopted the U.S. date, which is the third Sunday of June. It is celebrated on various days in many parts of the world, most commonly in the months of March, April and June. It complements similar celebrations honoring family members, such as Mother's Day, Siblings Day, and Grandparents' Day.
Can we conclude that has fathers day always been on a sunday?
A: no

Q: The groundhog (Marmota monax), also known as a woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. It was first scientifically described by Carl Linnaeus in 1758. The groundhog is also referred to as a chuck, wood-shock, groundpig, whistlepig, whistler, thickwood badger, Canada marmot, monax, moonack, weenusk, red monk and, among French Canadians in eastern Canada, siffleux. The name ''thickwood badger'' was given in the Northwest to distinguish the animal from the prairie badger. Monax was a Native American name of the woodchuck, which meant ''the digger''. Young groundhogs may be called chucklings. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas, but the groundhog is a lowland creature. It is found through much of the eastern United States across Canada and into Alaska
Can we conclude that is there a difference between groundhog and woodchuck?
A: no

Q: Castling consists of moving the king two squares towards a rook on the player's first rank , then moving the rook to the square over which the king crossed. Castling may only be done if the king has never moved, the rook involved has never moved, the squares between the king and the rook involved are unoccupied, the king is not in check, and the king does not cross over or end on a square in which it would be in check. Castling is one of the rules of chess and is technically a king move (Hooper & Whyld 1992:71).
Can we conclude that is it legal to castle out of check?
A:
no
