Q3642. Microplastics are generally defined as plastic particles smaller than:
Explanation
Tiny pieces of plastic that contaminate the environment are defined by their maximum dimension. These particles are typically smaller than half a centimeter. They can originate from the breakdown of larger plastic items or be intentionally manufactured for use in various products. Because of their small size, they are easily ingested by a wide range of organisms, entering the food chain and causing harm.
Q3643. The diplomatic and commercial embassies sent by the Chola emperors (such as Rajaraja I and Kulothunga I) to the court of the Chinese Song dynasty primarily resulted in?
Explanation
The diplomatic missions sent by Chola emperors like Rajaraja I and Kulothunga I to the Song court were primarily economic in nature. These embassies aimed to secure better trading conditions and royal protection for Indian merchant guilds operating in Chinese ports. As a result, Tamil merchants gained significant commercial privileges, which led to a surge in the export of textiles, spices, and ivory. This fostered a period of unprecedented economic prosperity and cultural exchange between South India and China.
Q3644. Which country possesses the world’s most extensive and heavily utilized domestic air transport network, accounting for a massive share of global domestic flights?
Explanation
The United States possesses the world’s most highly developed and utilized domestic air transport network. This dominance is driven by the country’s vast geographical size, high level of economic development, and a culture of mobility. Major hubs facilitate thousands of daily flights, connecting hundreds of cities. This internal network accounts for a significant portion of the total global domestic volume.
Q3645. Read the following statements regarding the impact of Globalisation on the Indian economy:
I. It led to an increase in the variety and quality of consumer goods available in the market.
II. It resulted in the contraction of the Information Technology and ITES sectors.
III. It exposed domestic small-scale industries to intense international competition.
IV. It necessitated the establishment of the Competition Commission of India to prevent anti-competitive practices.
V. It completely eliminated poverty and income inequality in the country.
Which of the statements given above are correct?
I. It led to an increase in the variety and quality of consumer goods available in the market.
II. It resulted in the contraction of the Information Technology and ITES sectors.
III. It exposed domestic small-scale industries to intense international competition.
IV. It necessitated the establishment of the Competition Commission of India to prevent anti-competitive practices.
V. It completely eliminated poverty and income inequality in the country.
Which of the statements given above are correct?
Explanation
Globalisation has profoundly impacted the Indian economy by increasing the variety and quality of consumer goods through international trade. However, it also exposed domestic small-scale industries to intense competition from global players. To address market imbalances, the government established the Competition Commission of India to prevent anti-competitive practices. While sectors like IT flourished, globalisation did not completely eliminate complex social issues.
Q3646. Regarding the potential for natural biodegradation of plastics, consider the following:
A. PET (Polyethylene Terephthalate)
B. PHA (Polyhydroxyalkanoate)
C. Glass
D. PLA (Polylactic Acid)
Which of the following represents the correct sequence in increasing order of biodegradation potential?
A. PET (Polyethylene Terephthalate)
B. PHA (Polyhydroxyalkanoate)
C. Glass
D. PLA (Polylactic Acid)
Which of the following represents the correct sequence in increasing order of biodegradation potential?
Explanation
Materials vary significantly in how quickly they break down in the environment. Natural minerals used in construction are extremely durable and show almost no biological decay. Common synthetic polymers also persist for centuries. In contrast, some newer plastics made from plant-based sources or produced by bacteria are designed to decompose more rapidly under certain conditions, making them a more sustainable option for specific applications.
Q3647. Consider the following two statements:
Statement I: The Chola state maintained a strong and specialized naval fleet to protect their expansive maritime trade routes.
Statement II: The Bay of Bengal was virtually converted into a "Chola Lake" during the reign of Rajendra I due to his naval supremacy.
Which of the following is correct?
Statement I: The Chola state maintained a strong and specialized naval fleet to protect their expansive maritime trade routes.
Statement II: The Bay of Bengal was virtually converted into a "Chola Lake" during the reign of Rajendra I due to his naval supremacy.
Which of the following is correct?
Explanation
The Chola Empire was a formidable maritime power that maintained a specialized naval fleet to protect its merchant ships from piracy and foreign interference. Under Rajendra I, the navy achieved such dominance that the Bay of Bengal was frequently referred to as a "Chola Lake." This naval supremacy allowed the Cholas to launch successful expeditions to Sri Lanka and Southeast Asia, ensuring their control over strategic sea lanes and solidifying their status as a major regional superpower.
Q3648. Consider the following statements regarding global air transport networks:
I. Air transport is the preferred mode for transporting high-value, lightweight, and perishable goods over long distances.
II. The development of air routes is highly dependent on favorable climatic conditions and the availability of sophisticated navigation infrastructure.
III. The Northern Hemisphere hosts a much denser network of air routes compared to the Southern Hemisphere.
IV. Air transport has significantly reduced the friction of distance, bringing remote continents closer in terms of travel time.
V. Air transport provides the most cost-effective solution for moving heavy bulk commodities like coal and iron ore internationally.
Which of the above statements is/are incorrect?
I. Air transport is the preferred mode for transporting high-value, lightweight, and perishable goods over long distances.
II. The development of air routes is highly dependent on favorable climatic conditions and the availability of sophisticated navigation infrastructure.
III. The Northern Hemisphere hosts a much denser network of air routes compared to the Southern Hemisphere.
IV. Air transport has significantly reduced the friction of distance, bringing remote continents closer in terms of travel time.
V. Air transport provides the most cost-effective solution for moving heavy bulk commodities like coal and iron ore internationally.
Which of the above statements is/are incorrect?
Explanation
Air transport is the fastest mode for high-value, perishable, or urgent goods, but it is not cost-effective for heavy bulk commodities like coal or iron ore. The high fuel costs and limited weight capacity of aircraft make them unsuitable for such low-value, high-volume items. These bulk materials are almost exclusively moved by sea or rail, where costs are lower.
Q3649. Primary microplastics are:
Explanation
Some microscopic plastic particles are intentionally produced for specific commercial uses. These include small beads used in personal care products like exfoliating scrubs or the tiny pellets that serve as raw materials for manufacturing larger items.
Q3650. Who among the following was the last recognized ruler of the Imperial Chola dynasty, whose defeat by the Pandyas in 1279 CE marked the formal end of the empire?
Explanation
Rajendra III was the final monarch of the Imperial Chola dynasty. During his reign, the empire faced increasing pressure from the rising power of the Pandyas and the Hoysalas. Despite his efforts to maintain authority, he was eventually defeated by the Pandyan king Maravarman Kulasekara Pandyan I in 1279 CE. This military collapse led to the total absorption of the remaining Chola territories into the Pandyan kingdom, marking the end of nearly four centuries of Chola imperial rule.Answer key for these questions
