    1. The discovery of stone tools belonging to the Acheulian age in a region known to have rich evidence of the Soanian period presents the possibility of continuity of the two Stone Age cultures at the site.
    2. The oldest dated Acheulian sites in India are those at Attirampakkam in Tamil Nadu, dating to 1.5 million years ago.

    Which of the above statements is/are correct?
    a. 1 only
    b. 2 only
    c. Both 1 and 2
    d. Neither 1 nor 2

    Explanation:

    Researchers from the Anthropological Survey of India (AnSI) have discovered a number of Acheulian artefacts (dated to about 1, 500,000–1,50,000 years ago) along with contemporary Soanian ones from an unexplored site at Ghumarwin in Bilaspur district of Himachal Pradesh. The site is close to the site where scientists in the 19th century discovered fossil remains of Sivapithecus, the last common ancestor of orangutans and humans.

    The discovery of stone tools belonging to the Acheulian age in a region known to have rich evidence of the Soanian period presents the possibility of continuity of the two Stone Age cultures at the site.

    The oldest dated Acheulian sites in India are those at Attirampakkam in Tamil Nadu, dating to 1.5 million years ago, whereas recent assessments of the South Asian Paleolithic (Stone Age culture) records have suggested that most Soanian assemblages are younger than Acheulian evidence in the Sivalik region. According to experts, the Soanian stone age cultures date to 600 ka (about 6,00,000) years ago.

    4. Consider the following statements regarding recently discovered material- graphene:
    1. Graphene made from honeycomb sheets of carbon just one atom thick.
    2. It is a three-dimensional form (allotrope) of carbon that consists of a single layer of carbon atoms arranged in a hexagonal lattice.
    3. Graphene has been described as wondrous stuff — of being the strongest material ever tested, almost 300 times stronger than steel.

    Which of the above statements is/are correct?
    a. 1 only
    b. 1 and 3
    c. 2 and 3
    d. 1, 2 and 3

    Answer: b

    Explanation:

    The 21st century seems set to become the age of graphene, a recently discovered material made from honeycomb sheets of carbon just one atom thick. It is a two-dimensional form (allotrope) of carbon that consists of a single layer of carbon atoms arranged in a hexagonal lattice. Graphene has been described as wondrous stuff — of being the strongest material ever tested, almost 300 times stronger than steel. It is also the best heat- and electricity-conducting material to be discovered. It could also become a valuable aid in filtering water. Researchers from Australia announced recently that they used a graphene-based product to make a water filter that can make highly-polluted sea water drinkable after just one pass.

    5. Recently, it has been found that the coral reefs in Seychelles face climate change threat. Seychelles is an archipelago island in which of the following Oceans?
    a. Indian Ocean
    b. Pacific Ocean
    c. Atlantic Ocean
    d. Arctic Ocean

    Answer: a

    Explanation:

    Beneath the crystal-clear waters of the Indian Ocean island nation of Seychelles, a fight is growing to save the coral reefs that shelter a range of creatures, from tiny invertebrates to the sprawling octopus, from climate change.

    The fragile reefs act both as a protective barrier for coastlines and an attraction for the tourists who keep the country’s economy going. But the reefs are also one of the first victims of rising ocean temperatures.

    Seychelles in some areas lost up to 90 percent of its coral reefs in 1998 in an environmental event known as bleaching, where coral in warming waters expel the colourful algae that live within their skeletons and, without their nutrients, starve. Another bleaching event occurred in 2016 after the reefs had partly recovered, said David Rowat, chairman of the Marine Conservation Society Seychelles.

    Already, conservationists have launched a number of coral reef restoration projects around the nation’s 115 islands. In one, more than 50,000 coral fragments have been nurtured and transplanted by a local charity, Nature Seychelles, in what the organization calls the world’s largest coral restoration program.
