 Q1. Five symbols on a rock art site at Iduhatty that closely resemble the symbols used at other rock and cave painting sites in Europe could point to the arrival of modern humans in south India between 10,000 and 40,000 years ago. Iduhatty is situated in the state of

1. TamilNadu
2. Kerala
3. Karnataka
4. Odisha

Answer (a)

Explanation:

Rock art symbols could point to the arrival of humans at the end of the last Ice Age in Nilgiris, says researcher

• Five symbols on a rock art site at Iduhatty in the Nilgiris district that closely resemble the symbols used at other rock and cave painting sites in Europe could point to the arrival of modern humans in the Nilgiris between 10,000 and 40,000 years ago.
• Palaeoanthropologist and leading rock art researcher Genevieve von Petzinger has identified 32 geometric signs of Ice Age Europe, which are seen with a remarkable commonality in caves and rock art sites across At Iduhatty, five of these symbols — the circle, cordiform, dot, finger fluting and quadrangle (names given to identify the different symbols) — are seen.
• That the symbols were also painted in red ochre (iron oxide) is also consistent with the European rock art sites.
• Ochre is a natural pigment, predominantly just an iron oxide with varying degrees of water molecules, which yields different colours, from yellow to Heat-treating the ochre causes a chemical change and makes it a really vibrant red. Ochre is a mineral, it doesn’t wash away or decay, allowing it to persist through the ages. Ancestral Homo species started using ochre over 2,50,000 years ago.

Q2. Consider the following statements

1. Ochre is a natural pigment, predominantly just an iron oxide with varying degrees of water molecules
2. It yields only the red colour characteristic of iron
3. Heat-treating the ochre causes a chemical change and makes it a really vibrant red
4. Ochre is a mineral, it doesn’t wash away or decay, allowing it to persist through the ages.

Q3. Consider the following statements about the Pangong Tso

1. The lake, a glacial melt, has mountain spurs jutting down referred to as ‘fingers’
2. It is a freshwater lake which freezes in winter

Which of the statements given above is/are incorrect?

1. 1 only
2. 2 only
3. Both 1 and 2
4. Neither 1 nor 2

Answer (b)

Explanation:

India deploys new docks and upgrades speed boats for Pangong Tso patrol

• The Army has deployed new landing docks and speedboats for patrolling on the Pangong Tso in eastern Ladakh, matching the Chinese deployments on the lake.
• This is part of an overall capability enhancement and infrastructure development taken up by India since the 2020 stand-off to plug deficiencies and catch up with the Chinese build-up along the Line of Actual Control (LAC).

• The new landing crafts have also been deployed at Sir Creek in Gujarat facing Pakistan, sources stated
• Pangong Tso has been an area of constant friction between India and China for a long India holds one-third of the 135-km-long boomerang-shaped lake.
• The lake, a glacial melt, has mountain spurs of the Chang Chenmo range jutting down referred to as ‘fingers’ and the brackish water lake freezes in winter.
