Explanation : 

Correct Answer: c. Statement-I is correct but Statement-II is incorrect.

Israel’s Diplomatic Relations with Arab States

Israel has forged new diplomatic relations with several Arab States, including the United Arab Emirates, Bahrain, Sudan, and Morocco. These groundbreaking agreements, collectively known as the Abraham Accords, were brokered by the United States in 2020.

Arab Peace Initiative

The Arab Peace Initiative, also known as the Saudi Initiative, is a proposal for an end to the Arab–Israeli conflict, which was endorsed by the Arab League in 2002 at the Beirut Summit. The initiative offers full normalization of relations between the Arab region and Israel, in exchange for a full withdrawal by Israel from the occupied territories (including East Jerusalem) and a “just settlement” of the Palestinian refugee problem based on UN Resolution 194.

Key Points

  1. Full Israeli Withdrawal: From all the Arab territories occupied since June 1967, including the Golan Heights, the remaining occupied Lebanese territories, and the territories of the future Palestinian state in the West Bank and Gaza Strip with East Jerusalem as its capital.
  2. Just Solution to Refugee Issue: Agreed upon in accordance with UN General Assembly Resolution 194.
  3. Establishment of Palestinian State: Sovereign independent Palestinian state on the territories occupied since June 4, 1967, in the West Bank and Gaza Strip with East Jerusalem as its capital.
  4. Normalization of Relations: Arab countries affirm the establishment of normal relations with Israel within the framework of this comprehensive peace.

The initiative was a significant move by the Arab states to openly express their willingness to resolve the conflict and recognize Israel upon the fulfillment of the outlined conditions. Despite this, the initiative has not led to a final peace agreement, as negotiations and peace efforts have faced numerous challenges and setbacks over the years.

Israel has expressed reservations about some aspects of the initiative, particularly the full return to the 1967 borders and the right of return for Palestinian refugees, arguing that these issues should be resolved through direct negotiations rather than through preconditions. Israel has not signed the Arab Peace Initiative.

The Arab Peace Initiative remains a reference point in discussions about resolving the Arab-Israeli conflict, and its principles are often cited in peace talks and diplomatic efforts to achieve a two-state solution.

Nagorno-Karabakh Conflict

Nagorno-Karabakh is a landlocked region in the South Caucasus that has been the subject of an intense and long-standing territorial dispute between Armenia and Azerbaijan. The area is predominantly inhabited by ethnic Armenians but is internationally recognized as part of Azerbaijan.

Nagorno-Karabakh Conflict Overview

Historical Context

The roots of the conflict can be traced back to the early 20th century when both Armenia and Azerbaijan became part of the Soviet Union. Nagorno-Karabakh was established as an autonomous region within the Azerbaijan Soviet Socialist Republic, despite its majority Armenian population. Tensions between the two ethnic groups simmered for decades, with occasional outbreaks of violence.

War and Ceasefire

The conflict escalated into a full-scale war following the weakening of Soviet authority and the eventual dissolution of the USSR in 1991. Nagorno-Karabakh declared independence, leading to a war that lasted until a Russia-brokered ceasefire was established in 1994. Despite the ceasefire, the region’s status remained unresolved, and sporadic clashes continued. The war resulted in tens of thousands of deaths and the displacement of hundreds of thousands of people.

Renewed Conflict and Recent Developments

In 2020, a new outbreak of hostilities, known as the Second Nagorno-Karabakh War, resulted in significant military and civilian casualties. After six weeks of intense fighting, a trilateral agreement was signed by Armenia, Azerbaijan, and Russia to end the hostilities. Azerbaijan regained control of some territories held by Armenian forces, and Russian peacekeeping forces were deployed to the region.

Current Situation

The status of Nagorno-Karabakh remains a contentious issue. The 2020 ceasefire agreement has not resolved the fundamental dispute over the region’s sovereignty. While Azerbaijan insists on its territorial integrity, many ethnic Armenians in Nagorno-Karabakh and the Armenian government continue to seek recognition of the region’s independence or its unification with Armenia. The presence of Russian peacekeepers and ongoing negotiations aim to maintain stability and find a lasting resolution to the conflict. However, the future of Nagorno-Karabakh is still uncertain, and the region remains a flashpoint in the South Caucasus.

Kherson and Zaporizhzhia Regions in Southeastern Ukraine

Kherson

Kherson is a region (oblast) located in the southern part of Ukraine, north of the Crimean Peninsula annexed by Russia in 2014. The administrative center is the city of Kherson. Known for its agricultural productivity, the region grows fruits and vegetables due to fertile soil and a favorable climate. Kherson also has a significant industrial sector, including shipbuilding and food processing.

The region’s access to the Black Sea via the Dnipro River makes it a crucial transit point for maritime trade. Its proximity to the Crimean Peninsula adds strategic significance amid the ongoing conflict between Ukraine and Russia.

Zaporizhzhia

Zaporizhzhia, also spelled Zaporizhia, is another region in southeastern Ukraine, known for its rich history and industrial strength. The capital is the city of Zaporizhzhia, home to the DniproHES hydroelectric power plant, one of Europe’s largest. The region is a key industrial area with a focus on heavy industry, including steel production, aluminum, and machinery.

Historically significant as the homeland of the Cossacks, particularly the Zaporozhian Cossacks, the region played a vital role in the development of Ukrainian national identity. Its strategic location along the Dnipro River has been important for centuries.

Impact of Russian Invasion

Both Kherson and Zaporizhzhia have been significantly affected by the Russian invasion of Ukraine that began in 2014 and escalated in February 2022. These regions witnessed military conflict, occupation, and contested control, leading to human suffering, displacement, and damage to infrastructure and the local economy. The ongoing conflict has brought international attention to these regions, emphasizing their importance to Ukraine’s sovereignty and territorial integrity.

Q39. Consider the following statements regarding mercury pollution:

1. Gold mining activity is a source of mercury pollution in the world.
2. Coal-based thermal power plants cause mercury pollution
3. There is no known safe level of exposure to mercury

How many of the above statements are correct?
a. Only one
b. Only two
c. All three
d. None

Question from UPSC Prelims 2023 GS Paper

Explanation : 

Correct Answer b. Only two

1. Gold mining activity is a source of mercury pollution in the world because mercury is used to extract gold from the ore. The process involves mixing mercury with the gold-containing materials, forming an amalgam. The amalgam is then heated, evaporating the mercury and leaving behind the gold. This process releases mercury vapor into the air and leaves behind mercury-contaminated waste.

2. Coal-based thermal power plants cause mercury pollution because coal contains trace amounts of mercury. When coal is burned in power plants, the mercury is released into the atmosphere. This airborne mercury can travel long distances and eventually settle in soil and water, where it can enter the food chain and accumulate in fish and other aquatic organisms.

3. Incorrect, Consider it like radiation from cell tower, low level does not cause too much or visible damage but high levels can.

2. Nebulae – Stars which brighten and dim periodically
3. Pulsars – Neutron stars that, are formed when massive stars run out of fuel and collapse

How many of the above pairs are correctly matched?
a. Only one
b. Only two
c. All three
d. None

Question from UPSC Prelims 2023 GS Paper

Explanation : 

Correct Answer – a. Only One

Cepheids – Stars Which Brighten and Dim Periodically

  • Cepheids are a type of variable star that exhibit a regular pattern of brightening and dimming. They are used as distance indicators in astronomy because their period of variation is directly related to their luminosity.

Nebulae – Giant Clouds of Dust and Gas in Space

  • Nebulae are indeed giant clouds of dust and gas in space. They are the birthplaces of stars, as the dust and gas within them come together under the force of gravity to form new stars.

Pulsars – Neutron Stars That Are Formed When Massive Stars Run Out of Fuel and Collapse

  • Pulsars are a type of neutron star that emit beams of electromagnetic radiation out of their magnetic poles. As the star rotates, these beams sweep across the sky, creating a pulsing effect when observed from Earth. They are formed when massive stars run out of fuel and collapse, so this pair is correctly matched.

Q35. Which reference to the role of biofilter in Recirculating Aquaculture System, consider the following statement

Q35. Which reference to the role of biofilter in Recirculating Aquaculture System, consider the following statement

1. Biofilters provide waste treatment by removing uneaten fish feed.
2. Biofilters convert ammonia present in fish waste in nitrate.
3. Biofilters increase phosphorus as nutrient for fish in water.

How many of the statements given above are correct?
a. Only one
b. Only two
c. All three
d. None

Question from UPSC Prelims 2023 GS Paper

Explanation : 

Correct Answer – b Only Two

Role of Biofilters in Recirculating Aquaculture Systems

In a Recirculating Aquaculture System (RAS), biofilters are crucial for maintaining water quality and providing effective waste treatment. These systems rely on biofilters for two primary functions:

1. Removing Uneaten Fish Feed

Biofilters are instrumental in removing uneaten fish feed and other suspended solids from the water. This function is vital to prevent the accumulation of waste materials in the system, which can lead to poor water quality and adversely affect fish health.

2. Converting Ammonia to Nitrate

Fish waste typically contains ammonia, which is toxic to fish in high concentrations. Biofilters utilize beneficial bacteria to convert ammonia into nitrite and then into nitrate through a process known as nitrification. Nitrate, being less harmful to fish, can be subsequently removed from the system via water exchange or denitrification.

Limitation of Biofilters in Phosphorus Management

While biofilters effectively convert harmful compounds like ammonia into less harmful ones like nitrate, they do not increase phosphorus levels in the water. Phosphorus is an essential nutrient for fish growth, but excess phosphorus can lead to issues such as algal blooms. Therefore, biofilters help maintain overall water quality but do not directly contribute to phosphorus nutrient levels.

So, Statements 1 and 2 are correct, while Statement 3 is incorrect. Therefore, the answer is b. Only two.
