Explanation:

1. Which of the following was NOT a result of the Chernobyl Nuclear Power Plant disaster?

A. quick public notification

• The accident, which occurred at reactor 4 of the plant in the early morning of April 26, 1986, resulted when operators took action in violation of the plant's procedures. Operators ran the plant at very low power, without adequate safety precautions and without properly coordinating or communicating the procedure with safety personnel.

• The four Chernobyl reactors were pressurized water reactors of the Soviet RBMK design, or Reactor BolshoMoshchnosty Kanalny, meaning "high-power channel reactor." Designed to produce both plutonium and electric power, they were very different from standard commercial designs and employed a unique combination of a graphite moderator and water coolant.

• The reactors were highly unstable at low power, due to control rod design and "positive void coefficient," factors that accelerated the nuclear chain reaction and power output if the reactors lost cooling water.

• These factors all contributed to an uncontrollable power surge that led to Chernobyl 4's destruction. The power surge caused a sudden increase in heat, which ruptured some of the pressure tubes containing fuel.

• The hot fuel particles reacted with water and caused a steam explosion, which lifted the 1,000-metric-ton cover off the top of the reactor, rupturing the rest of the 1,660 pressure tubes, causing a second explosion and exposing the reactor core to the environment. The fire burned for 10 days, releasing a large amount of radiation into the atmosphere.

• The Chernobyl plant did not have the fortified containment structure common to most nuclear power plants elsewhere in the world. Without this protection, radioactive material escaped into the environment.

• After the accident, the crippled Chernobyl 4 reactor was originally enclosed in a concrete structure that was growing weaker over time. As of November 2018, it is now encased in an enormous steel and concrete sarcophagus which is expected to last 100 years or more.

• Officials shut down reactor 2 after a building fire in 1991 and closed Chernobyl 1 and 3 in 1996 and 2000, respectively.

B. people displaced from their homes

C. radiation poisoning

D. respiratory diseases and cancer

2. The Byzantine Empire lasted for a thousand years before falling to

A. Bosnia and Herzegovina.

B. Austria.

C. the Ottoman Turks.

The Byzantine Empire lasted for a millennium after the fall of the Roman Empire, ending with the Ottoman conquests in 1453. While the Roman Empire's capital was Rome (for most of its history), the Byzantine Empire's capital city was Constantinople, which was previously called Byzantium, and today is Istanbul.

D. Hungary.

1. Quick public notification was not a result of Chernobyl Nuclear power station disaster as once the incident took place, a number of people died due to radiation poisoning and thousands experienced respiratory problems while people were displaced of their homes in lakh. Option - A

2. The Byzantine Empire lasted for a 1000 years until they were captured by The Ottoman Turks after which, the Turks became very stronger and started driving the neighbouring kings towards India as the Turks conquered their territories. Option - C
