GENERAL KNOWLEDGE

Detailed explanation-1: -The original carrier for the plague-infected fleas thought to be responsible for the Black Death was the black rat. The bacterium responsible for the Black Death, Yersinia pestis, was commonly endemic in only a few rodent species and is usually transmitted zoonotically by the rat flea.

Detailed explanation-2: -Where did the Black Death originate? The plague that caused the Black Death originated in China in the early to mid-1300s and spread along trade routes westward to the Mediterranean and northern Africa. It reached southern England in 1348 and northern Britain and Scandinavia by 1350.

Detailed explanation-3: -The death toll was so high that it had significant consequences on European medieval society as a whole, with a shortage of farmers resulting in demands for an end to serfdom, a general questioning of authority and rebellions, and the entire abandonment of many towns and villages.
