1. Question
1 pointsThe Kimberley Process (KP), recently seen in the news, primarily aims to:
Correct
Answer: c
Explanation:
India has assumed the chair of the Kimberley Process (KP) for the year 2026.
About Kimberley Process (KP):
- It is a coalition of governments, civil society and the diamond industry to eliminate the trade in so-called conflict diamonds.
- Conflict diamonds are defined by the relevant United Nations Security Council resolution (UNSC resolution 1459) as “rough diamonds used by rebel movements or their allies to finance conflict aimed at undermining legitimate governments”.
- Based on a mandate from the United Nations, the Kimberley Process regulates the international trade in rough diamonds.
- Participants in the scheme are required to:
- Satisfy ‘minimum requirements’ and establish national legislation, institutions and import/export controls;
- Commit to transparent practices and to the exchange of critical statistical data;
- Trade only with other participants in the Scheme;
- Certify shipments as conflict-free.
- Currently it has 60 participants, representing 86 countries (with the EU as a single participant) which account for more than 99% of the global rough diamond production and trade.
- The KP meets twice a year at the Intersessional and Plenary meetings. It is chaired by a participating country on an annual, rotating basis.
- As a consensus-based body, the KP relies on the constructive engagement from all participants of the tripartite structure.
What is the Kimberley Process Certification Scheme (KPCS)?
- It is the mechanism the KP uses to prevent the trade of conflict diamonds.
- Under this scheme, the Government implements safeguards on shipments of rough diamonds and certifies the diamond as conflict-free.
- According to this Scheme, each rough diamond shipment must be accompanied by the Kimberley Process certificate and transported in a tamper-resistant container.
- The KP certificate states the authenticity of the rough diamond.
- Since 2003, India has been actively participating in the KPCS process.
- The Department of Commerce is the nodal Department.
- Gem & Jewellery Export Promotion Council (GJEPC) is designated as the KPCS Importing and Exporting Authority in India.
- GJEPC is responsible for issuing KP Certificates and is also the custodian of KP Certificates received in the country.
Hence option c is the correct answer.

Question 4 of 10
4. Question
1 pointsThe HbA1c test is primarily used to assess which of the following?
Correct
Answer: b
Explanation:
A new study has found that glycated hemoglobin (HbA1c), a laboratory test commonly used in India for detecting type-2 diabetes, may not accurately reflect blood glucose levels.
About HbA1c Test:
- A hemoglobin A1C (HbA1C) test is a blood test that shows your average level of blood glucose, also called blood sugar, over the past two to three months.
- Glucose is a type of sugar in your blood that comes from the foods you eat. Your cells use glucose for energy.
- A hormone called insulin helps glucose get into your cells.
- If you have diabetes, your body doesn’t make enough insulin, or your cells don’t use it well.
- As a result, glucose can’t get into your cells, so your blood glucose levels increase.
- Glucose in your blood sticks to hemoglobin, a protein in your red blood cells (RBCs).
- As your blood glucose levels increase, more of your hemoglobin will be coated with glucose.
- An A1C test measures the percentage of your RBCs that have glucose-coated hemoglobin.
- An A1C test can show your average glucose level for the past three months because:
- Glucose sticks to hemoglobin for as long as the RBCs are alive.
- RBCs live about three months.
- High A1C levels are a sign of high blood glucose from diabetes.
- Diabetes can cause serious health problems, including heart disease, kidney disease, and nerve damage.
- But with treatment and lifestyle changes, you can control your blood glucose levels.
Hence option b is the correct answer.

Question 5 of 10
5. Question
1 pointsThe Sansha Yongle Blue Hole, recently seen in the news, is located in which of the following water bodies?
Correct
Answer: c
Explanation:
The Sansha Yongle Blue Hole, also known as the Dragon Hole, sits in the South China Sea and has drawn scientific attention for more than a decade.
About Dragon Hole:
- The Dragon Hole is the popular name for the Sansha Yongle Blue Hole, a massive marine sinkhole in the South China Sea.
- Blue holes are steep-sided underwater cavities, often formed in limestone landscapes, that later flooded as sea levels rose.
● It is the deepest known underwater sinkhole in the world.
● It is about 25 kilometers from the Discovery Reef in the South China Sea.
- The local fishermen call it the‘eye’of the South China Sea.
● It is believed to be 301.19 meters deep, beating Dean’s Blue Hole in the Bahamas by almost 100 meters.
- The almost vertical blue hole measures 130 meters in diameter at its surface entrance and 36 meters at its very bottom, where there is literally no water flow or exchange with the rest of the ocean.
- Water in the lower part of a deep blue hole like Dragon Hole is stagnant and anoxic with nearly no water circulation and thus unfavorable for most sea life, but nonetheless can support large colonies of bacteria.
- However, at least 20 ocean species thrive in the upper section of the hole, where there is a unique ecosystem characterized by ample oxygen and nutrients.
Hence option c is the correct answer.
