    A. Africa
    B. Antarctica
    C. Europe
    D. Australia
    Ans. B
    Explanation: In a recent development, scientists have found particles of a rare isotope of iron (Fe-60) in Antarctica snow. It is believed that they have been originated from nearby supernovae. It will help in understanding the structure and origin of interstellar dust clouds, according to scientists.
  6. Chandrayaan-2 Mission was launched by which vehicle?
    B. PSLV C11
    C. GSLV F11
    D. PSLV C45
    Ans. A
    Explanation: Chandrayaan-2 is the second mission to the moon which was launched on 22 July, 2019 by India's Geosynchronous Satellite Launch Vehicle (GSLV Mk III). It reached lunar orbit on 19 August, 2019. Despite the crash-landing of the Lander, ISRO confirmed that all the instruments are onboard the orbiter and are working well.
  7. In 2019, Nobel Prize in Chemistry is given for which development?
    A. For the development of Lithium-ion batteries.
    B. To develop protein.
    C. For developing cryoelectron microscopy.
    D. None of the above
    Ans. A
    Explanation: The recipients of the Nobel Prize in Chemistry 2019 are John B. Goodenough, M. Stanley Whittingham and Akira Yoshino for the development of lithium-ion batteries. Do you know that this lightweight, rechargeable and powerful battery can be used in mobile phones to laptops, electric vehicles? Not only this, it can even store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society.
  8. Which of the following statements is/are correct regarding bipolar disorder?
    A. It is a mental health condition.
