Q352. The following question consists of two statements, Assertion (A) and Reason (R). Choose the correct option.
Assertion (A): The Sustainable Development Goals (SDGs) are often described as indivisible and integrated.
Reason (R): Progress in one SDG is inherently linked to progress in others, meaning economic, social, and environmental dimensions must be balanced simultaneously.
Assertion (A): The Sustainable Development Goals (SDGs) are often described as indivisible and integrated.
Reason (R): Progress in one SDG is inherently linked to progress in others, meaning economic, social, and environmental dimensions must be balanced simultaneously.
Explanation
The Sustainable Development Goals are described as indivisible because they are deeply interconnected. For example, improving education often leads to better health outcomes and higher economic productivity. Conversely, failing to address climate change can undermine progress in poverty reduction. Therefore, the goals must be pursued as a package, ensuring that social, economic, and environmental progress are balanced and mutually reinforcing.
Q353. When light passes from a denser medium to a rarer medium, it bends:
Explanation
When light travels from an optically denser medium, like water, into a rarer medium, like air, its speed increases. This change in speed causes the light ray to bend away from the normal line at the boundary. If the angle of incidence exceeds a certain critical value, the light will undergo total internal reflection and remain within the denser medium entirely.
Q354. Consider the following statements regarding Chalcolithic pottery styles in Rajasthan:
I. Black and Red Ware (BRW) is uniquely identified with the Ahar culture.
II. Ochre Coloured Pottery (OCP) is prominently associated with the Ganeshwar culture.

II. Ochre Coloured Pottery (OCP) is prominently associated with the Ganeshwar culture.
III. Painted Grey Ware (PGW) is the defining pottery of the early Chalcolithic period.
IV. The pottery was largely handmade in the earliest phases and gradually shifted to wheel-made.

Explanation
Chalcolithic Rajasthan is identified by distinct pottery traditions, such as the Black and Red Ware of Ahar and the Ochre Coloured Pottery of Ganeshwar. These ceramics were often wheel-made and featured various decorations. However, claiming that Painted Grey Ware is the defining pottery of the early Chalcolithic is incorrect. Painted Grey Ware is actually associated with the transition into the Iron Age.

V. Steatite was sourced from South Rajasthan and North Gujarat.
Which of the combination of statements given above is correct?
Explanation
The Harappans maintained a complex network for sourcing raw materials. Gold came from South India, while copper was sourced from Rajasthan and Oman. Lapis Lazuli was imported from Afghanistan. Jade was obtained from Central Asia, and steatite was sourced from Rajasthan and Gujarat. This extensive trade network ensured a steady supply of materials for their sophisticated craft industries and economy.
Q356. The word ‘Sovereign’ in the Preamble implies all of the following except:
Explanation
