Q3622. Regarding soil remediation, consider the following statements:
I. Ex-situ remediation involves treating the contaminated soil at the site without excavation.
II. Soil washing is a physical/chemical remediation technique.
III. In-situ techniques are generally less expensive than ex-situ techniques.
IV. Thermal desorption uses heat to vaporize contaminants from soil.
Which of the above statement(s) is/are correct?
I. Ex-situ remediation involves treating the contaminated soil at the site without excavation.
II. Soil washing is a physical/chemical remediation technique.
III. In-situ techniques are generally less expensive than ex-situ techniques.
IV. Thermal desorption uses heat to vaporize contaminants from soil.
Which of the above statement(s) is/are correct?
Explanation
Techniques for cleaning contaminated ground are categorized by where the treatment takes place and the methods used. Physical processes like washing and thermal methods that vaporize toxins are common. Treating the soil directly in its original location is generally more economical and less disruptive than removing it for processing elsewhere. These various strategies are essential for restoring polluted land to a safe and productive state.
Q3623. Consider the following statements:
Statement I: ‘Khad-Lakad’ was a cess collected from villagers to provide wood and fodder for the state officials or the ruler’s camp when they visited the area.
Statement II: Such cesses were always adjusted against the primary land revenue demand and never posed an extra burden on the peasants.
Which of the following is correct?
Statement I: ‘Khad-Lakad’ was a cess collected from villagers to provide wood and fodder for the state officials or the ruler’s camp when they visited the area.
Statement II: Such cesses were always adjusted against the primary land revenue demand and never posed an extra burden on the peasants.
Which of the following is correct?
Explanation
Khad-Lakad was a customary cess where villagers were forced to provide fodder and wood for state officials or the ruler’s camp during their travels. These cesses were not adjusted against the main land revenue; instead, they were an additional burden on the peasants. Such demands were often unpredictable and added significantly to the overall economic hardship faced by rural communities.
Q3624. While the Nataraja is the most celebrated form, which of the following was also a highly popular subject for bronze casting during the Chola period?
Explanation
While the Nataraja is the most iconic Chola bronze, other religious subjects were also highly popular among sculptors and patrons. The Somaskanda, which depicts Lord Shiva seated with his consort Parvati and their child Skanda, was a very common theme. These bronzes were often used as processional icons in temples. In contrast, Buddhist and Jain figures were less common during this period of Hindu resurgence, and the Ashokan capital belongs to a much earlier historical era.
Q3625. In the context of the global transport network, what defines an "Entrepot" port?
Explanation
An Entrepot is a specialized port that acts as a central collection and distribution point for regional trade. Goods are imported from various sources, stored in warehouses, and eventually re-exported to other destinations, often after being processed or repackaged. These ports thrive by leveraging strategic locations along major shipping lanes, with Singapore and Rotterdam being classic examples of such maritime intermediaries.
Q3626. The excessive accumulation of which element in the soil leads to sodicity, causing poor soil structure?
Explanation
The physical structure of soil is heavily influenced by its chemical composition. When a specific alkali metal accumulates in high concentrations, it causes soil particles to disperse, leading to poor drainage and aeration. This condition makes the ground hard and difficult for roots to penetrate, which significantly hinders plant growth. Proper management often involves adding amendments like gypsum to displace the problematic element.
Q3627. Consider the following statements regarding Chola trade and overseas expansion:
I. Manigramam and Ayyavole were prominent and powerful merchant guilds.
II. Trade embassies were actively dispatched to the Song dynasty in China.
III. The Cholas established mercantile cantonments known as Virapattinams.
IV. The Srivijaya empire controlled the strategic maritime chokepoint of the Malacca Strait.
V. The Cholas were major exporters of war-horses to the Arab world.
Which of the above combination of statements is correct?
I. Manigramam and Ayyavole were prominent and powerful merchant guilds.
II. Trade embassies were actively dispatched to the Song dynasty in China.
III. The Cholas established mercantile cantonments known as Virapattinams.
IV. The Srivijaya empire controlled the strategic maritime chokepoint of the Malacca Strait.
V. The Cholas were major exporters of war-horses to the Arab world.
Which of the above combination of statements is correct?
Explanation
The Chola period was an era of intense maritime activity. Powerful merchant guilds like Manigramam and Ayyavole managed international commerce, and the state sent diplomatic missions to China to facilitate trade. The empire established specialized mercantile towns known as Virapattinams. This expansion often brought them into conflict with the Srivijaya empire, which controlled the vital Malacca Strait. However, the Cholas were primarily importers of horses from Arabia rather than exporters, making the fifth statement incorrect.
Q3628. Match the major ports in List I with their geographical locations or countries in List II and select the correct answer using the codes given below:
| Major Port | Geographical Location/Country |
|---|---|
| A. Rotterdam | i. China |
| B. Singapore | ii. India |
| C. Shanghai | iii. Netherlands |
| D. Mumbai | iv. Southeast Asia |
Explanation
Major global ports are defined by their strategic national and regional locations. Rotterdam serves as the primary gateway for the Netherlands and much of Europe. Singapore is a critical hub for Southeast Asia, overseeing the Malacca Strait. Shanghai is China’s leading port at the mouth of the Yangtze, while Mumbai serves as a vital maritime gateway for India’s western coast.
Q3629. Given below are two statements, one is labelled as Assertion (A) and the other is labelled as
Reason (R).
Assertion (A): The share of the manufacturing sector in India’s GDP has remained relatively stagnant at around 16-17% for several decades despite reforms.
Reason (R): The rapid growth of the services sector and structural bottlenecks in infrastructure and labor markets hindered the proportional expansion of manufacturing.
Which of the following is correct?
Reason (R).
Assertion (A): The share of the manufacturing sector in India’s GDP has remained relatively stagnant at around 16-17% for several decades despite reforms.
Reason (R): The rapid growth of the services sector and structural bottlenecks in infrastructure and labor markets hindered the proportional expansion of manufacturing.
Which of the following is correct?
Explanation
Despite economic reforms, the manufacturing sector’s share in India’s GDP has remained relatively constant at about 16-17%. This stagnation is primarily explained by the exceptional growth of the services sector, which bypassed traditional industrial expansion. Furthermore, persistent structural bottlenecks, including inadequate infrastructure and rigid labor regulations, have hindered the manufacturing sector from achieving proportional growth seen in other developing industrializing economies.
Q3630. Which of the following is an example of an organochlorine pesticide known for persisting in soil?
Explanation
A notorious synthetic chemical once widely used in agriculture and disease control is known for its extreme persistence in the environment. This substance does not break down easily and can remain in the soil for decades. Because it accumulates in the fatty tissues of animals, it has caused significant harm to wildlife populations, leading to widespread bans on its use in many countries.Answer key for these questions
