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 30-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Untimed

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.
  • Open to guests. Normal practice needs no sign-in.

Timed CBT

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 30 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

Inventions and Discoveries Level 2 GK Quiz: Chronology and Nobel Prizes

This Level 2 Inventions and Discoveries quiz tests chronology, scientist matching and Nobel Prize years for landmark findings in science. Questions ask you to order discoveries in time, work out gaps between a discovery and its prize, and spot mismatched pairs. Aptitude360 gives an explanation with every question so the facts behind each answer are clear.

What Level 2 of this inventions set tests

  • Chronological ordering of events, from Hooke's cork cells and Jenner's vaccine to Brown's nucleus and Chadwick's neutron
  • Gaps in years between a discovery and its Nobel Prize, as with X-rays and the transistor
  • Matching scientists with discoveries: electron, insulin, neutron, wireless telegraphy
  • Statement checks on Einstein, Marie Curie, Becquerel and Watson and Crick
  • Odd-one-out and not-correctly-matched pairs

Key concepts for discovery chronology

  • Which Nobel Prizes came earliest, such as Ross for malaria before Banting and Macleod for insulin
  • Robert Brown, not Hooke, described the cell nucleus
  • Becquerel found radioactivity, while the Curies found radium
  • The first transistor was a semiconductor amplifier

Revision tips for this level

  • Build a single timeline of discovery years and prize years together
  • Practise subtracting discovery years from prize years for gap items
  • Read every statement fully, since one wrong detail such as the field of a prize makes it false

Who this Level 2 quiz suits

Students who have finished the basics of this topic and are revising static GK for the general awareness section of competitive exams.

FAQs about Inventions and Discoveries – GK Quiz with Answers – Level 2

Did Marie Curie win two Nobel Prizes?
Yes. She shared the 1903 Nobel Prize in Physics and won the 1911 Nobel Prize in Chemistry for discovering polonium and radium.
Who discovered the structure of DNA?
James Watson and Francis Crick described the double helix structure of DNA. They shared the 1962 Nobel Prize with Maurice Wilkins.
