When was the Black Death that affects the world's population?
Correct Answer
C. 1350
Explanation
The Black Death, a devastating pandemic caused by the bacterium Yersinia pestis, occurred between 1347 and 1351. It is believed to have originated in Asia and spread through fleas on rats, leading to the deaths of millions of people in Europe, Asia, and Africa. While the peak of the pandemic occurred in 1348 and 1349, it continued to affect the world's population until 1351. Therefore, 1350 is a plausible answer as it falls within the timeframe of the Black Death.

Which of these affects world's population mostly?
Correct Answer
A. Increase in birthrate
Explanation
An increase in birthrate affects the world's population mostly because it leads to a higher number of births, which in turn increases the overall population. When birth rates are high, there is a greater number of individuals being added to the population each year, resulting in population growth. This can have various impacts on society, including increased demand for resources, strain on infrastructure, and potential challenges in providing healthcare, education, and other essential services to a larger population.

Which continent's population dropped during the Plague of Justinian?
Correct Answer
A. Europe
Explanation
During the Plague of Justinian, Europe's population dropped significantly. The Plague of Justinian, which occurred in the 6th century, was one of the deadliest pandemics in history. It is estimated that it caused the death of up to 25 million people, resulting in a significant decline in Europe's population. This plague was caused by the bacterium Yersinia pestis, which is also responsible for the Black Death in the 14th century. The high mortality rate and rapid spread of the disease contributed to the population decline in Europe during this time.
7.
Which of these is the most populated?
Correct Answer
A. Asia

With countries like China and India, which have the highest populations globally, Asia has a significant advantage in terms of population. Additionally, Asia has a diverse range of cultures, languages, and ethnicities, contributing to its high population density. Europe, Africa, and South America have smaller populations compared to Asia, making Asia the correct answer.
