RAS PrelimsIndian Economy · Service Sector: Role, Challenges and Opportunities
Q4021. Read the following statements regarding the relationship between the service sector and employment: Statement I: India’s economic growth over the past two decades has been criticized as ‘jobless growth’ because employment elasticity in the service sector is low. Statement II: The majority of the workforce transitioning out of agriculture is successfully absorbed by the high-skill IT sector. Select the correct response:
Explanation
India’s growth is often described as ‘jobless’ because the employment elasticity in the high-value service sector is relatively low. This means that significant increases in economic output do not result in a corresponding increase in jobs. Furthermore, the high-skill IT sector cannot easily absorb the large number of workers leaving agriculture, as these individuals often lack the specialized technical training.

Q4022. Identify the incorrect statement regarding tiger census methods in India.
Explanation
Tiger estimation in India is a massive undertaking conducted every four years, not annually. While early methods relied on pugmarks, modern census techniques integrate camera trapping, DNA analysis, and digital tools like the M-STrIPES application. This quadrennial cycle allows for a comprehensive assessment of tiger populations, their prey base, and habitat status across the entire national network of tiger reserves.

RAS PrelimsIndian Polity and Governance · Union-State Relations
Q4024. In the context of All-India Services (IAS and IPS), how is the disciplinary control managed between the Union and the States?
Explanation
All-India Service officers are recruited and trained by the Central Government but assigned to state cadres. Consequently, the state government exercises immediate disciplinary and administrative control over them during their posting. However, the ultimate power to take major disciplinary actions, such as dismissal or removal from service, rests solely with the Union Government, ensuring the independence and security of tenure for these officers.
Q4025. Consider the following statements regarding the consequences of deforestation: I. It disrupts the local hydrological cycle, often leading to reduced precipitation in the area. II. It increases the albedo of the cleared land, affecting local energy balances. III. It results in an immediate increase in the amount of organic carbon securely stored in the soil. Which of the above statement(s) is/are correct?
Explanation
Deforestation significantly alters local environments by reducing evapotranspiration, which can lead to lower rainfall. It also typically increases surface albedo, as cleared land reflects more sunlight than dark forest canopies. Contrary to increasing soil carbon, the removal of vegetation and subsequent soil disturbance usually leads to a rapid loss of organic carbon. This happens as the soil organic matter decomposes more quickly.

Q4026. The rapid expansion of the gig economy within the service sector has had which of the following primary effects on the labor market?
Explanation
The expansion of the gig economy has introduced a new level of flexibility into the labor market, allowing workers to choose tasks via digital platforms. However, this shift has also raised serious concerns regarding the lack of traditional social security, health benefits, and long-term job security for these workers. It creates a precarious employment environment where individuals operate outside standard labor protections.

Q4028. Read the following statements regarding the Mathura and Gandhara schools of art: Statement I: The Mathura school relied heavily on grey sandstone and focused on realistic musculature. Statement II: The Gandhara school predominantly used spotted red sandstone and depicted spiritual serenity. Which of the following is correct?
Explanation
The Mathura and Gandhara schools represent distinct regional artistic developments in ancient India. Mathura relied on indigenous red sandstone to create spiritual images, while Gandhara employed grey schist to depict Buddha with realistic Greco-Roman features. Because the descriptions of their material usage and stylistic focus were swapped in the statements, both are considered factually inaccurate representations of these schools.
Q4029. What is the chemical formula of stratospheric ozone, and how is it naturally formed?
Explanation
Stratospheric ozone has the chemical formula O 3 . It forms naturally through a process where high-energy ultraviolet radiation splits diatomic oxygen molecules into individual atoms. These highly reactive oxygen atoms then collide and bond with other oxygen molecules to create triatomic ozone. This continuous cycle of creation and destruction maintains a steady-state concentration of ozone, which filters harmful UV radiation from reaching Earth.

Q4030. Arrange the four modes of supply under the General Agreement on Trade in Services (GATS) from Mode 1 to Mode 4 in their correct sequential order: A. Commercial presence B. Consumption abroad C. Presence of natural persons D. Cross-border supply Select the correct sequence:

International trade in services is classified into four distinct modes under the GATS framework. Mode 1 involves cross-border supply, such as online consulting. Mode 2 covers consumption abroad, like tourism. Mode 3 refers to commercial presence, such as opening a foreign branch. Mode 4 involves the presence of natural persons, where individuals travel to provide services. These modes define how services are delivered.
