Q2. {Health – Issues}: Consider the following statements regarding Heavy Metals:
They are a group of chemical elements with relatively high atomic weights and densities.
They can either be essential or toxic to living organisms.
Heavy metals like iron, mercury, cadmium, and arsenic are toxic to living organisms, even in trace amounts.
Which of the above statement(s) is/are correct?
1 and 2 only
2 and 3 only
1 and 3 only
1, 2 and 3
Explanation
Statement 1 is correct
Heavy metals are a group of chemical elements with relatively high atomic weights and densities.
These metals occur naturally in Earth’s crust, but human activities like industrial processes, mining, and burning fossil fuelshave increased their release into the environment.
Statement 2 is correct
Depending on their concentration and the specific metal, heavy metals can either be essential or toxic to living organisms.
Statement 3 is incorrect
Essential Heavy Metals:Heavy metals, such as copper, zinc,and iron, are essential micronutrients living organisms require in trace amounts for biochemical and physiological functions. E.g., iron is crucial for oxygen transport in hemoglobin and zinc for enzymatic reactions.
Toxic Heavy Metals: Heavy metalslike lead, mercury, cadmium, arsenic, and chromium can be toxic to living organisms, even at low concentrations. They can cause a range of health problems.
Answer: (a) 1 and 2 only

India is an associate member of the Arctic Council.
How many of the above statement(s) is/are correct?
Only one
Only two
Only three
All four
Explanation
Statement 1 is correct
The Arctic Council is the leading intergovernmental forum promoting cooperation, coordination, and interaction among the Arctic States,Arctic Indigenous Peoples, and other Arctic inhabitants.
It was formally established in 1996 through the Ottawa Declaration.
Statement 2 is incorrect
The Arctic Councilcannot implement/enforce its guidelines, assessments, or recommendations. The responsibility belongs to individual Arctic States or international bodies.
Statement 3 is correct
All the Arctic states are members of the Arctic Council.
Statement 4 is incorrect
India is not an Associate member, but India was given the Observer status in 2013.
Answer: (b) Only two
Q4. {S&T} The term “Dark Patterns” in the context of digital design is associated with which of the following?
A user experience design strategy involving subtle visual cues and psychological triggers to enhance user engagement and satisfaction.
A comprehensive set of practices for user interfaces, ensuring user transparency, informed consent, and data privacy.
A social media platform that uses personalized recommendations to keep users engaged, even if those recommendations adversely affect the users.
None of the above.
Explanations
“Dark patterns” refer to design techniques that use deceptive and manipulative tactics to nudge or trick users into taking actions they may not want to take, often for the benefit of the designer.
It is adeceptive practice employed to influence user behavior in a way that benefits the company implementing it.
Answer: (c) A social media platform that uses personalized recommendations to keep users engaged, even if those recommendations adversely affect the users.
Q5. {Envi – Conservation} Consider the following statements regarding ‘Marine Cloud Brightening (MCB)’:
It is a geoengineering technique designed to increase the albedo of marine clouds with the goal of reflecting sunlight and mitigating global warming.
It involves releasing sulphur aerosols into the atmosphere to create artificial clouds over the ocean, thus cooling the Earth’s surface.
Which of the above statement(s) is/are correct?
1 only
2 only
Both
None
Explanation
Statement 1 is correct
Marine cloud brightening (MCB) is a geoengineering technique that producesbrighter and whiter low marine clouds. Thus increasing the albedo.
Such clouds reflect sunlight away from the ocean’s surface and protect corals from bleaching.
Statement 2 is incorrect
MCB does not involve releasing chemicals likesulfuraerosols into the atmosphere.
Stratospheric aerosol injection is a proposed method of solar geoengineering to reduce global warming. It involves introducing sulfur aerosols (which are highly reflective) into the stratosphere to create a cooling effect via global dimming and increased albedo.
Marine cloud brightening (MCB) involves spraying tiny seawater dropletsinto the air.
As the tiny seawater droplets evaporate, they leave behind sea salt. These additional sea salts, when incorporated into a cloud, brighten the cloud (increasing the albedo).
Answer: (b) 1 only
Q6. {Envi – Degradation} Consider the following statements regarding the ‘Mountain Chicken Frog’:
It is endemic to the Western Ghats.
Its conservation status has improved over the past decade due to successful breeding and reintroduction programs.
Its large makes it particularly vulnerable to predation and habitat loss.
The Mountain Chicken Frog is primarily found in the Caribbean Islands of Dominica, Montserrat, Guadeloupe, Saint Kitts, Nevis, etc.
Statement 2 is incorrect
Mountain chicken frog faces imminent extinction in the wild.
It is virtually wiped out from the island of Dominica by the chytrid fungus.
Statement 3 is correct
Due to its large size, the Mountain Chicken Frog is always at risk of predation and is considered one of themost vulnerable species to habitat loss among all amphibians.
