Question

Match the following scientists and their discoveries during Renaissance period. 
(A) Cordus - (i) Carbon dioxide
(B) Helmount - (ii) Anatomy of human body  
(C) William Harvey - (iii) Ether
(D) Vesalius - (iv) Blood Circulation

Accepted Answer

The correct option is 3:

This matching question tests your knowledge of critical scientific breakthroughs made during the Renaissance and Early Modern periods, which laid the foundation for modern science. The correct pairings are: **(A) Cordus - (iii) Ether**, **(B) Helmount - (i) Carbon dioxide**, **(C) William Harvey - (iv) Blood Circulation**, and **(D) Vesalius - (ii) Anatomy of human body**.  * **Cordus** (Valerius Cordus) is credited with synthesizing and describing sulfuric ether around 1540.
  * **Helmont** (Jan Baptist van Helmont) was a Flemish chemist who introduced the term "gas" and was the first to recognize and isolate "gas sylvestre," which is now known as carbon dioxide (CO2).
  * **William Harvey** is famously known for his work *De Motu Cordis* (1628), where he definitively described and demonstrated the full circulation of blood throughout the body.
  * **Vesalius** (Andreas Vesalius) is considered the founder of modern human anatomy. His groundbreaking work, *De Humani Corporis Fabrica* (1543), provided detailed and accurate anatomical descriptions of the human body, correcting centuries of reliance on Galen's teachings.The incorrect option is 1: This option incorrectly links Cordus to Blood Circulation and Helmont to Ether, which reverses their actual discoveries. William Harvey is credited with the discovery of blood circulation.

The incorrect option is 2: This option incorrectly links Cordus to Blood Circulation and Vesalius to Ether. Vesalius's principal contribution was in human anatomy, not the discovery of Ether.

The incorrect option is 4: This option presents a completely incorrect mapping. For instance, it incorrectly links Cordus to Carbon dioxide and William Harvey to Ether, contradicting the well-established historical facts of these Renaissance-era breakthroughs.
