General Knowledge Trivia: Science, History, Inventors & Pop Culture

Michael Jackson was inducted into the Rock and Roll Hall of Fame twice - first in 1997 as a member of The Jackson 5, and again in 2001 as a solo artist. This dual honor recognizes his contributions both as part of a family group and as an iconic solo performer.

'Romancing with Life' is the autobiography of veteran Bollywood actor Dev Anand, published in 2007. The book chronicles his journey in the Indian film industry spanning several decades. Gulzar and Dilip Kumar have also written autobiographies, but with different titles. Shabana Azmi is an actress but not associated with this autobiography.

India shares its international land border with 6 countries: Pakistan, China, Nepal, Bhutan, Bangladesh, and Myanmar. This is a standard fact taught in Indian geography curriculum. Some sources may mention 7 including Afghanistan through Pakistan-occupied Kashmir, but 6 is the most widely accepted answer in competitive examinations.

Chandrayaan-1 was launched on October 22, 2008, and stopped sending radio signals on August 28, 2009. From launch date to loss of contact: Oct 2008 (remaining days: ~10) + Nov 2008 (30) + Dec 2008 (31) + Jan 2009 (31) + Feb 2009 (28) + Mar 2009 (31) + Apr 2009 (30) + May 2009 (31) + Jun 2009 (30) + Jul 2009 (31) + Aug 2009 (28 days) = approximately 312 days total in lunar orbit. The mission was designed for 2 years but operated for 312 days before contact was lost.

Michael Jackson received one Golden Globe Award during his lifetime - the 'Best Original Song' award in 1984 for 'Beat It' (though some sources cite it as a sales-based award). This is a straightforward factual question about his awards tally. The options of 2, 3, or 4 awards are incorrect.

Michael Jackson first performed the moonwalk publicly during the Motown 25: Yesterday, Today, Forever television special on March 25, 1983, while performing 'Billie Jean.' This performance was broadcast on May 16, 1983. The Ed Sullivan Show was from an earlier era, Wembley shows were later in his career, and 'Invincible' was an album, not a specific show.

Michael Jackson held numerous Guinness World Records throughout his career. While the exact count varied as new records were set and some were broken, 13 is a commonly cited number for records he simultaneously held at his peak. These included records for album sales, concert attendance, charity support, and other achievements. The option of 5 is too low, while 15 is an overestimate.

Benjamin Banneker (1731-1806) was a free African-American mathematician, astronomer, and inventor known for his almanacs and role in surveying the boundaries of Washington D.C. He is widely recognized as one of the first African-American inventors and scientists. George Washington Carver, Elijah McCoy, and Bessie Blount came later.

Igor Sikorsky (1889-1972) was a Russian-American aviation pioneer who designed and flew the world's first practical helicopter. While he worked on various aircraft including fixed-wing planes, his most significant contribution was the development of the helicopter in the 1940s.

Sir Frank Whittle (1907-1996) was a British RAF engineer who invented and patented the turbojet engine in 1930, leading to jet propulsion for aircraft. The jet engine revolutionized aviation by enabling much higher speeds and altitudes than piston engines. Radar was developed by Robert Watson-Watt, sonar is for underwater detection, and ethyl gasoline was developed by Thomas Midgley.

Thomas Jefferson (1743-1826), the third U.S. President, was a prolific inventor and polymath who invented the swivel chair, the spherical sundial, the moldboard plow (a better plow design), and the cipher wheel (for cryptography). George Washington, Alexander Hamilton, and John Adams were not known for such inventions.

Benjamin Franklin invented the glass armonica (or harmonica) in 1761, a musical instrument consisting of graduated glass bowls mounted on a horizontal spindle and played by touching them with wet fingers. The banjo has African origins, the oboe and clarinet were developed in Europe earlier. Franklin's instrument became popular in classical music for its ethereal tone.

DDT (Dichloro-diphenyl-trichloroethane) is an organochlorine insecticide that was widely used but later banned due to environmental concerns. The name reflects its chemical structure: two phenyl rings connected to a trichloroethane group with two chlorine atoms. Options B, C, and D incorrectly substitute parts of the chemical name.

Dr. Sarvepalli Radhakrishnan served as the second President of India from 1962 to 1967, succeeding Rajendra Prasad who was the first President. Radhakrishnan was a renowned philosopher and statesman before his presidency. His birthday (September 5) is celebrated as Teachers' Day in India.

Lal Bahadur Shastri served as the second Prime Minister of India from 1964 to 1966, succeeding Jawaharlal Nehru who was the first Prime Minister. Shastri led India during the 1965 India-Pakistan war and gave the slogan 'Jai Jawan, Jai Kisan' (Hail the soldier, Hail the farmer).

CCl4 is Carbon tetrachloride, a chemical compound consisting of one carbon atom bonded to four chlorine atoms. The name reflects the 'tetra' (four) chlorine atoms around carbon. Options A, B, and D incorrectly substitute elements or misrepresent the structure.

TNT is Tri-nitro toluene, a yellow solid explosive compound consisting of toluene (a methylbenzene ring) with three nitro groups (NO2) attached. The 'tri' indicates three nitro groups, and 'toluene' is the base aromatic compound. Options A, C, and D incorrectly describe the structure or naming.

CFC stands for Chloro-fluoro-carbon, compounds containing carbon, chlorine, and fluorine atoms (e.g., CFC-11, CFC-12). These were widely used as refrigerants and propellants but are now banned due to ozone layer depletion. Options A, B, and C incorrectly name completely different compounds.

MIC stands for Methyl isocyanate, a highly toxic organic compound with the formula CH3NCO. The other options are incorrect - isocyanide has a different bonding structure, methylene isocyanide is not a valid compound name, and isocynasium is a misspelling.
