Consider the following statements about famous scientists and their contributions. Which option correctly describes them so that all listed statements are accurate?

Difficulty: Easy

Correct Answer: All of the above

Explanation:


Introduction / Context:
This question checks your general knowledge of important scientists and inventors and whether you can correctly match them with their major contributions. Such questions often present several statements and ask which are correct together, so you must evaluate each one rather than guess based on one familiar name.


Given Data / Assumptions:

  • Three scientist-contribution pairs are listed.
  • We need to decide whether each individual statement is accurate.
  • The final option “All of the above” will be correct only if all three statements are factually correct.


Concept / Approach:
Sir Richard Arkwright is widely regarded as a key figure in the Industrial Revolution due to his innovations in spinning machinery and factory systems, which leads to his description as the father of the Industrial Revolution. Michael Faraday is famous for his discoveries in electromagnetism and electrochemistry and is also credited with discovering benzene. Thomas Alva Edison developed many devices, including the phonograph and important improvements related to motion picture cameras. If each of these statements matches historical facts, then the combined option “All of the above” is correct.


Step-by-Step Solution:
Step 1: Evaluate statement about Sir Richard Arkwright. His spinning frame and factory system made him a central figure in the Industrial Revolution, so calling him its father is acceptable in general knowledge context.Step 2: Examine statement about Michael Faraday. He discovered benzene and is renowned for pioneering experiments in electromagnetism, including induction and laws of electrolysis, which matches the description.Step 3: Check statement about Thomas Alva Edison. He developed the phonograph and contributed to motion picture camera technology through devices such as the Kinetoscope.Step 4: Since all three statements are factually sound in general knowledge terms, the combination option must be correct.Step 5: Select “All of the above” as the final answer.


Verification / Alternative check:
Biographies and science history summaries confirm Arkwright’s central role in early industrialisation, Faraday’s benzene discovery and electromagnetic work, and Edison’s inventions in sound recording and moving images. Each statement is a simplified but accurate reflection of their major contributions. Cross-checking with a few reliable references will validate each pairing.


Why Other Options Are Wrong:
Option A alone: Recognises Arkwright correctly but ignores the correctness of the other two statements.Option B alone: Acknowledges Faraday but does not account for the other correct statements.Option C alone: Accepts Edison’s work but again fails to include the others, making it incomplete.


Common Pitfalls:
Examinees sometimes focus only on one scientist they know well and ignore the rest, leading them to choose a single-statement option instead of the combined one. Another trap is to doubt a statement that summarises complex contributions in a short phrase. A good strategy is to think calmly about each pair and ask whether there is any clear contradiction with known facts. If all statements appear consistent with your learning, “All of the above” is likely to be correct.


Final Answer:
All three scientist-contribution statements are accurate, so the correct choice is All of the above.
