Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 35-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Inventions and Discoveries GK Level 3 Practice Quiz on Nobel Prize Facts

This Level 3 Inventions and Discoveries GK quiz is for General Awareness aspirants in the advanced stage of preparation who already know the basic discoverer and discovery pairs. It covers X-rays, radioactivity, the cell and its nucleus, subatomic particles, vaccines, DNA and the transistor. On Aptitude360, the questions also test which scientists shared certain Nobel Prizes and the subject in which each prize was given.

Topics covered in this Inventions and Discoveries set

  • Röntgen's X-rays and Becquerel's discovery of radioactivity in uranium salts
  • Marie Curie's work on polonium and radium, and why her later Nobel was in Chemistry
  • Hooke's cork cells in Micrographia versus Brown's description of the cell nucleus
  • Thomson's electron and Chadwick's neutron
  • Jenner's smallpox vaccine, Ross's work on the malaria parasite, Fleming's penicillin and the insulin Nobel
  • Watson and Crick's DNA structure, the transistor and the basis of Mendeleev's periodic table

Key concepts to revise for discovery and Nobel Prize questions

  • Separating the year of a discovery from the year its Nobel Prize was awarded
  • Arranging discoveries and Nobel Prizes in chronological order
  • Co-winners, such as Wilkins with Watson and Crick, and Bardeen and Brattain with Shockley
  • Common traps, such as giving the nucleus to Hooke or insulin to Fleming

Revision tips for advanced science GK

  • Build a timeline with separate columns for the discovery year and the Nobel year
  • Learn the exact Nobel citation, for example Einstein's prize for the photoelectric effect and not relativity
  • In statement and pair questions, check each claim on its own before choosing an option

Who this GK quiz suits

This set suits aspirants of competitive exams with a General Awareness section who are in the final revision stage and have finished the easier levels of this topic.

FAQs about Inventions and Discoveries – GK Quiz with Answers – Level 3

What is the difference between an invention and a discovery?
A discovery finds something that already exists in nature, such as the electron or radioactivity. An invention creates something new that did not exist before, such as the transistor.
Who discovered X-rays?
X-rays were discovered by the German physicist Wilhelm Röntgen. He received the first Nobel Prize in Physics for this discovery.
Who discovered radioactivity?
Henri Becquerel discovered radioactivity when he found that uranium salts give off radiation on their own. He shared the Nobel Prize in Physics with Pierre and Marie Curie.
Who invented the transistor?
The first transistor was built by John Bardeen and Walter Brattain at Bell Labs. They shared the Nobel Prize in Physics with William Shockley.
