Current Affairs MCQs

751In which year did Christopher Columbus first reach the Americas?
Explanation

Christopher Columbus first reached the Americas in 1492, landing in the Bahamas after sailing westward from Spain in search of a new trade route to Asia, an expedition that opened the door to extensive European exploration and colonization of the Americas. His voyage was sponsored by the Spanish monarchs Ferdinand and Isabella, following his earlier unsuccessful attempts to secure funding from Portugal. 1472, 1482 and 1502 are close numerical distractors designed to test precise knowledge of the actual landing year. Columbus made three further voyages to the Americas over the following decade, though he died in 1506 still believing he had reached parts of Asia.

752Which country was the first to establish a national health insurance system, introduced under Otto von Bismarck in 1883?
Explanation

Germany became the first country to establish a national health insurance system, introduced in 1883 under Chancellor Otto von Bismarck as part of a broader set of social welfare reforms intended partly to undercut the growing appeal of socialist political movements among German workers. The system required employers and employees to jointly contribute to a fund covering workers' medical care during illness. France, Sweden and Britain are tempting distractors, as each later developed its own national health or social insurance systems, but well after Germany's pioneering 1883 reform. Bismarck's broader social insurance program also later introduced accident insurance and old-age pensions, laying foundational groundwork for the modern welfare state.

753Which is considered the first fully synthetic plastic, invented in 1907?
Explanation

Bakelite, invented in 1907 by Belgian-American chemist Leo Baekeland, is considered the first fully synthetic plastic, created from a chemical reaction between phenol and formaldehyde rather than being derived from any natural plant or animal material. Its durability, heat resistance and electrical insulating properties made it enormously useful for early 20th-century manufacturing, particularly in electrical products and household goods. Nylon, Polyester and PVC are tempting distractors, as each is another significant synthetic material developed later than Bakelite. Bakelite's invention is widely regarded as launching the modern plastics industry, which has since transformed manufacturing and consumer products worldwide.

754Which country launched Venera 7, the first spacecraft to successfully transmit data after landing on Venus, in 1970?
Explanation

The Soviet Union launched Venera 7, the first spacecraft to successfully transmit data after landing on the surface of Venus, in 1970, briefly surviving the planet's extraordinarily harsh surface conditions, including crushing atmospheric pressure and scorching temperatures. This achievement marked a major milestone in Soviet planetary exploration efforts during the ongoing Space Race. France, China and United States are tempting distractors, as each later developed its own significant planetary exploration programs, but well after the Soviet Union's pioneering Venera missions. Venus remains one of the most hostile planetary environments ever successfully explored by spacecraft, given its extreme heat and pressure.

755Which country launched Syncom 3, the world’s first geostationary communications satellite, in 1964?
Explanation

The United States launched Syncom 3, the world's first geostationary communications satellite, in 1964, successfully maintaining a fixed position relative to a specific point on the Earth's surface by orbiting at the same speed as the planet's rotation. This breakthrough technology enabled continuous, reliable satellite communication and broadcasting, including live television coverage of that year's Tokyo Olympics. Soviet Union, Japan and United Kingdom are tempting distractors, as each later developed its own significant satellite communications programs, but well after the pioneering American Syncom missions. Geostationary satellites remain essential today for television broadcasting, weather monitoring and global telecommunications.

756Which is considered the first fully synthetic fiber, developed in 1935?
Explanation

Nylon, developed in 1935 by American chemist Wallace Carothers at DuPont, is considered the first fully synthetic fiber, created entirely from chemical compounds rather than derived from any natural source like cotton, wool or silk. It was famously first marketed to the public in the form of nylon stockings, which became enormously popular after their commercial introduction in 1940. Polyester, Rayon and Acrylic are tempting distractors, as each is another significant synthetic or semi-synthetic fiber, but all were developed after nylon, with rayon actually being a semi-synthetic material derived partly from natural cellulose. Nylon's success launched an entire industry of synthetic fibers that transformed the global textile and manufacturing sectors.

757Who built one of the first commercially successful typewriters in the 1860s and 1870s?
Explanation

Christopher Latham Sholes, an American inventor, built one of the first commercially successful typewriters in the 1860s and 1870s, later selling the rights to his design to the Remington company, which began mass-producing and marketing the machine. Sholes is also widely credited with developing the QWERTY keyboard layout, still the standard arrangement used on keyboards worldwide today. Isaac Singer, Thomas Edison and Elias Howe are tempting distractors, as each is instead associated with other significant inventions, respectively the sewing machine, the light bulb and also the sewing machine. Typewriters dramatically transformed office work and written communication throughout the late 19th and 20th centuries.

758Which American college became the first coeducational institution of higher learning in the United States, admitting women from 1837?
Explanation

Oberlin College, located in Ohio, became the first coeducational institution of higher learning in the United States, admitting women alongside men beginning in 1837, a pioneering step at a time when higher education was almost universally restricted to men only. The college was also notably progressive on issues of race, admitting Black students from its earliest years as well. Princeton College, Harvard College and Yale College are tempting distractors, as each remained exclusively male institutions for many more decades before eventually admitting women. Oberlin's early commitment to coeducation and racial inclusion made it a significant pioneer in American higher education reform.

759Who were the first people to reach the deepest known point of the ocean, the Challenger Deep, in 1960?
Explanation

Jacques Piccard and Don Walsh became the first people to reach the deepest known point of the ocean, the Challenger Deep in the Mariana Trench, in January 1960, descending nearly 11,000 metres aboard the bathyscaphe Trieste. Their historic dive demonstrated that human-crewed vessels could survive the crushing pressure found at the ocean's deepest known point. James Cameron alone, Robert Ballard and team, and Auguste Piccard and Paul Kipfer are tempting distractors, with James Cameron later becoming the first person to reach the Challenger Deep solo, in 2012, and Auguste Piccard, Jacques's father, having earlier achieved pioneering high-altitude balloon flights instead. The Challenger Deep's extreme depth remains far greater than the height of Mount Everest above sea level.

760Which country is credited with issuing the first paper banknotes in Europe, in 1661?
Explanation

Sweden is credited with issuing the first paper banknotes in Europe, in 1661, produced by the Stockholms Banco, a precursor to Sweden's modern central bank, in response to a shortage of the country's cumbersome and impractically heavy copper coinage. This early experiment with paper money, however, ultimately led to overprinting and financial collapse just a few years later. France, England and Netherlands are tempting distractors, as each later developed its own paper currency systems, but generally after Sweden's pioneering, if short-lived, 1661 banknotes. Sweden's central bank, the Riksbank, founded shortly afterward in 1668, remains the oldest central bank still in operation in the world today.
