General Knowledge Trivia Mix

x=y++ + x++: x = 35 + 20 = 55, then y becomes 36, x becomes 56. y= ++y + ++x: y increments to 37 first, x increments to 57 first, so y = 37 + 57 = 94. Final output: 57 94. Requires understanding pre and post increment.

x = 5. x<<2 (left shift by 2) = 5 * 4 = 20. x>>2 (right shift by 2) = 5 / 4 = 1 (integer division). Output: 5,20,1. Left shift multiplies by 2^n, right shift divides by 2^n.

A static variable at file scope (outside any function) has internal linkage - it's visible to all functions in the same file but not to other files. Option B correctly states that all functions in file1.c can access it. Option A is incorrect because there's no requirement for functions to be declared static.

Ruth Handler, co-founder of Mattel, created the original Barbie concept in 1959, inspired by a German doll called Bild Lilli. She revolutionized the toy industry with the adult-figured doll.

Barbie debuted in the United States at the American International Toy Fair in New York in 1959, not in the UK. The UK market came later as part of Barbie's global expansion.

Barbie was officially introduced on March 9, 1959 at the American International Toy Fair in New York. This date is historically recognized as Barbie's birthday.

The original 1959 Barbie doll featured a black-and-white zebra-striped swimsuit with a signature topknot ponytail and tightly curled bangs, exactly as described in the question.

Turritopsis nutricula is a species of jellyfish capable of reverting back to juvenile stage through transdifferentiation, making it biologically immortal. It can theoretically live indefinitely.

The Belcher's Sea Snake (Hydrophis belcheri) is widely regarded as the most poisonous snake, with venom estimated to be many times more potent than most terrestrial snakes including taipans and cobras.

The Slow Loris has toxin-secreting glands near its elbows. Before sending offspring to forage, it licks these glands to coat its young with poison, providing them with chemical defense against predators.

The Golden Poison Dart Frog (Phyllobates terribilis) from Colombia is the most poisonous vertebrate. One frog has enough poison (batrachotoxin) to kill 10 adult humans.

The Basket Starfish, a type of brittle star, can have up to 50 arms - far more than any other animal. Unlike millipedes which have many legs, or octopuses which have 8 arms, basket stars have the most arms.

Wolffia (duckweed) is the world's smallest flowering plant. Entire plants are only 0.6-1.5 mm in size - smaller than a pinhead, making it impossible for any other option to be correct.

Rafflesia arnoldii produces the world's largest single flower, reaching up to 1 meter (3 feet) in diameter and weighing up to 11 kg. It grows in Southeast Asian rainforests and is a parasitic plant.

The Methuselah Tree, a Great Basin bristlecone pine in California, is over 4800 years old and considered the oldest known living non-clonal organism. The Ashoka Tree, Giant Tortoise, and Australian Snail are not the oldest living organisms. Methuselah's location is kept secret to protect it from vandalism.

In seahorses, the male carries the fertilized eggs in a pouch and gives birth to the young ones. This is unique among animals. Piranhas, Giraffe Whales (likely a typo), and Star Fish do not have this reproductive role reversal.

Starfish (sea stars) do not have a centralized brain. They have a nerve ring and radial nerves but no brain. Piranhas, Cucumber Fish (likely sea cucumber), and Squit (likely Squid) all have brains or neural ganglia.

Richard Nixon was forced to resign in 1974 due to the Watergate scandal, which involved a break-in at the Democratic National Committee headquarters and cover-up attempts. FD Roosevelt, Jimmy Carter, and Bill Gates were not involved in Watergate.
