Q3662. Consider the following two statements regarding the transitional period following the Chola decline:
Statement I: The power vacuum created by the subsequent decline of the Pandyas and Hoysalas eventually paved the way for the rise of the Vijayanagar Empire.
Statement II: Harihara and Bukka officially established the Vijayanagar Empire in 1336 CE to consolidate Hindu resistance in the South.
Which of the following is correct?
Statement I: The power vacuum created by the subsequent decline of the Pandyas and Hoysalas eventually paved the way for the rise of the Vijayanagar Empire.
Statement II: Harihara and Bukka officially established the Vijayanagar Empire in 1336 CE to consolidate Hindu resistance in the South.
Which of the following is correct?
Explanation
The decline of major regional powers like the Pandyas and Hoysalas following the Chola collapse created a period of political instability. This fragmentation made the South vulnerable to invasions from the Delhi Sultanate. In response to these external threats and the need for regional stability, Harihara and Bukka founded the Vijayanagar Empire in 1336 CE. Their objective was to consolidate local Hindu resistance and preserve traditional South Indian culture, leading to the rise of a new imperial era.
Q3663. Given below are two statements, one labeled as
Assertion (A) and the other as Reason (R):
Assertion (A): Pipeline transport is highly capital-intensive to construct but extremely cost-effective to operate.
Reason (R): Once laid, pipelines require minimal maintenance, operate continuously without empty return journeys, and are unaffected by surface weather conditions.
Select the correct answer from the options given below:
Assertion (A) and the other as Reason (R):
Assertion (A): Pipeline transport is highly capital-intensive to construct but extremely cost-effective to operate.
Reason (R): Once laid, pipelines require minimal maintenance, operate continuously without empty return journeys, and are unaffected by surface weather conditions.
Select the correct answer from the options given below:
Explanation
Pipelines require a massive initial investment for construction, making them highly capital-intensive. However, once operational, they are extremely cost-effective because they eliminate the need for fuel, drivers, and return journeys. They provide a continuous, weather-independent flow of goods with minimal maintenance, leading to very low operating costs per unit of volume transported over their long lifespan in the field.
Q3664. Read the following statements regarding Foreign Direct Investment (FDI) and Foreign Portfolio Investment (FPI):
I. FDI implies investment in a foreign country involving management control.
II. FPI generally involves short-term investment in financial assets like stocks and bonds.
Which of the statements given above is/are correct?
I. FDI implies investment in a foreign country involving management control.
II. FPI generally involves short-term investment in financial assets like stocks and bonds.
Which of the statements given above is/are correct?
Explanation
Foreign investment is broadly classified into Foreign Direct Investment and Foreign Portfolio Investment. FDI involves a long-term interest and usually includes a significant degree of management control over a business in a foreign country. In contrast, FPI typically involves shorter-term investments in financial assets such as stocks and bonds without direct control over the company operations. Both are essential.
Q3665. The term "single-use plastics" refers to:
Explanation
Many modern convenience items are designed to be used only once before they are thrown away or recycled. These products, such as straws, bags, and food packaging, are typically made from durable synthetic polymers that do not decompose in the environment. Because they are used for such a short time but last for centuries, they contribute disproportionately to the growing global waste problem.
Q3666. Identify the incorrectly matched pair regarding the late medieval South Indian dynasties and their primary capital or political center after the decline of the Cholas.
Explanation
The Pandyas were based in Madurai, the Hoysalas ruled from Dwarasamudra, and the Later Cholas continued to use Gangaikonda Cholapuram as their political center. However, the Kakatiya dynasty was centered in the Deccan region of present-day Telangana, with Warangal (Orugallu) as their primary capital. Thanjavur was the historical capital of the Cholas and later became a seat for the Pandyas and Nayakas, but it was never the capital of the Kakatiya kingdom, making this pair incorrect.
Q3667. Consider the following statements:
Statement I: The ‘Big Inch’ is one of the most famous pipelines in the world, located in the United States.
Statement II: It carries milk from dairy farms in the Midwest to processing plants in New York.
Which of the following is correct?
Statement I: The ‘Big Inch’ is one of the most famous pipelines in the world, located in the United States.
Statement II: It carries milk from dairy farms in the Midwest to processing plants in New York.
Which of the following is correct?
Explanation
The Big Inch is a famous 24-inch diameter pipeline built in the United States during World War II. It was designed to transport crude oil from the oil fields of Texas to refineries on the East Coast to ensure a secure energy supply. It was never intended for, nor is it physically used for, the transport of milk products.
Q3668. What was the effect of systematic tariff reduction under globalization on domestic manufacturing in India?
Explanation
Under the process of globalization, India systematically reduced import tariffs, which had a profound impact on domestic manufacturing. This policy change ended the era of high protectionism and forced domestic firms to face international competition. To survive, Indian companies were compelled to become more cost-efficient and quality-conscious. This shift led to improvements in productivity, better resource allocation, and overall industrial modernisation.
Q3669. In India, the manufacture, import, stocking, distribution, sale and use of identified single-use plastic items were banned from which date?
Explanation
To combat the rising tide of environmental pollution, the Indian government implemented a significant nationwide ban on the production and use of numerous disposable plastic items. This regulation took effect in the middle of twenty twenty-two. By targeting products with high littering potential and low utility, the policy aims to reduce the environmental footprint of non-biodegradable waste and encourage more sustainable alternatives.
Q3670. The Hoysala dynasty, which played a crucial role in the geopolitics that led to the decline of the Cholas, ruled primarily from which present-day region?
Explanation
The Hoysala dynasty was a prominent South Indian power that ruled between the tenth and fourteenth centuries. Their kingdom was primarily located in the Malnad and plateau regions of present-day Karnataka. From their capital at Dwarasamudra (modern-day Halebidu), they played a crucial role as a buffer state and a major military power in the conflicts between the Cholas and the Chalukyas. They are also celebrated for their unique and highly decorative temple architecture found throughout the Karnataka region.Answer key for these questions
