Q1. In which region of India is Dogri language chiefly spoken?
Correct
Answer: b
Explanation:
In recent years, growing concern has emerged over the gradual decline of the Dogri language in the Jammu region.
About Dogri Language:
It is an Indo-Aryan language, part of the larger Indo-European family of languages.
It is spoken in India, chiefly in the Jammu region of Jammu and Kashmir.
It is also spoken in the state of Himachal Pradesh and in northern Punjab, other parts of Jammu and Kashmir, and elsewhere.
The earliest written reference to Dogri (using the paleonym Duggar) is found in the Nuh sipihr (“The Nine Heavens”), written by the poet Amir Khosrow in 1317 CE.
It has its origin in the old Indo-Aryan language, i.e., language of the Vedas and Laukik Sanskrit.
Like other modern Indo-Aryan languages, Dogri has also passed through Old Indo-Aryan (Sanskrit) and Middle Indo-Aryan (Pali, Prakrit, and Apabhramsha) stages of development and entered the modern Indo-Aryan stage around the 10th century A.D.
Hence, it shows its three-fold process of development of its sound structure, expressing its affinity with Shaurseni Prakrit.
Initially written in the Takri script, Dogri now uses the Devanagari script, which is also utilized by several other Indian languages.

Q3. Consider the following statements regarding the Dilmun Civilization, recently seen in the news:
It was located in the Eastern Mediterranean region.
It acted as an important trading link between Mesopotamia and the Indus Valley Civilization.
Which of the statements given above is/are correct?
Correct
Answer: b
Explanation:
Kuwait’s Failaka Island has just yielded one of its most significant secrets in decades: a 4,000-year-old temple belonging to the powerful Bronze Age Dilmun civilization.
About Dilmun Civilization:
Dilmun (Telmun) was a civilization located in the eastern part of the Arabian Peninsula.
Dilmun was mainly located on the islands of Bahrain and Failaka Island in Kuwait.
It also had a presence in parts of Saudi Arabia, Qatar, Oman, and the nearby Iranian coast in the Persian Gulf.
Although this was quite an old civilization, it is much less famous than the four cradles of civilization of the Old World, i.e., Mesopotamia, Ancient Egypt, the Indus Valley Civilization, and the Yellow River Civilization.
Growth:
The Dilmun civilization first took shape towards the end of the 4th millennium BCE, around 3200 to 3000 BCE, starting out as a modest trading hub.
By the early 3rd millennium BCE, it had grown into a recognised power in the region.
Dilmun acted as a central point for trade between two of the biggest ancient civilizations: Mesopotamia (modern-day Iraq) and the Indus Valley Civilization (modern-day Pakistan and India).
Goods like copper, pearls, and other materials passed through Dilmun. This made it a rich and powerful place.
The Land of Copper:
One of Dilmun’s most important roles was providing copper. Copper was a vital metal in the Bronze Age, used for tools, weapons, and art.
Dilmun helped supply this important metal to Mesopotamia, which needed it for its growing cities and armies.
Decline:
After 1600 BCE, the empire began to dwindle, then slowly declined like many other empires.
It was eventually absorbed into Mesopotamia and Persia at a later date.
Archaeologists have foundmany ancient sites in Bahrain and Kuwait that match the descriptions of Dilmun.
These sites include old settlements, burial mounds, and artifacts like unique stamp seals.

Q9. With reference to Benzene, consider the following:
It is a colorless liquid with a sweet odor.
It evaporates into the air very quickly and doesn’t dissolve in water.
It is used to make dyes and detergents.
How many of the above statements are correct?
Correct
Answer: b
Explanation:
Two centuries after Benzene discovery, the simple yet revolutionary molecule benzene continues to shape our world.
Benzene is a colorless liquid with a sweet odor.
Discovered by: In 1825, the English scientist Michael Faraday, isolated a new substance from the oily residue of the illuminating gas used to light London and August Kekulé proposed a revolutionary cyclic structure for benzene.
Properties of Benzene:
It evaporates into the air very quickly and dissolves slightly in water.
It is highly flammable and is formed from both natural processes and human activities.
Natural sources of benzene include volcanoes and forest fires.
It forms the base for styrene, phenol, cyclohexane, nylon, and polystyrene.
It belongs to the BTEX family (Benzene, Toluene, Ethylbenzene, Xylene) of so called aromatics because of their sweet, pleasant smell.
Application of Benzene:
Some industries use benzene to make other chemicals which are used to make plastics, resins, and nylon and synthetic fibers.
Benzene is also used to make some types of rubbers, lubricants, dyes, detergents, drugs, and pesticides.
Impact on Health: Long-term exposure to Benzene leads to acute myeloid leukaemia, aplastic anemia, and myelodysplastic syndrome.
