Q2723. Assertion (A): Ganga plain is the most densely populated part of India. Reason (R): Ganga is the most harnessed river of India.
Explanation
Assertion (A) is True: The Ganga Plain, a part of the Indo-Gangetic Plain supports one of the highest population densities in India. This is primarily due to its fertile alluvial soil, which makes the land highly productive for agriculture. The region benefits from abundant water resources, a favorable climate, and flat terrain, all of which have historically encouraged dense human settlements. Reason (R) is True: The Ganga is the most harnessed river in India, with its waters extensively used for irrigation, drinking, industrial purposes, and hydroelectric projects. This extensive harnessing has been pivotal for the region’s agricultural productivity and development. R is not the correct explanation of A: The reason alone does not directly explain the high population density in the Ganga Plain. Population density is influenced by a variety of factors, including geographical, historical, economic, and cultural factors. The availability of fertile land for agriculture, historical settlement patterns, economic opportunities, and cultural factors play significant roles in determining population density.

Q2724. Assertion (A): In Australia, cattle rearing is done more for meat than for milk. Reason (R): Australians are traditionally non vegetarians
Explanation
Assertion (A) is True: Australia is one of the world’s largest exporters of beef and has a significant cattle industry focused on meat production. The country’s vast grazing lands and favorable climate make it ideal for raising cattle for beef. According to the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES), beef production is a major agricultural activity, and Australia exports a significant portion of its beef to international markets. In contrast, dairy farming, while still important, is smaller in scale compared to the beef industry. Reason (R) is True: It is true that meat, particularly beef and lamb, forms a significant part of the Australian diet. This dietary habit reflects the cultural preferences in Australia, where a majority of the population consumes meat. Reason (R) is not the correct explanation of Assertion(A):
The reason provided does not directly explain why cattle rearing in Australia is predominantly for meat production. The primary factors influencing this include:
Geographical and Climatic Conditions: Australia’s expansive rangelands and favorable climate support large-scale grazing, making beef cattle rearing more efficient and economically viable than dairy farming. Agricultural Practices: The country’s agricultural infrastructure and export orientation have historically promoted beef production, irrespective of the local dietary habits.

Q2725. The best performance in terms of Human Development among Asian countries is by:
Explanation
Among the given options, South Korea had the best performance in terms of Human Development Index (HDI) in the year 2000. South Korea consistently ranked higher than China, Malaysia, and the Philippines due to its strong education system, healthcare, high life expectancy, and economic development.
Additional insight:
HDI is a composite index developed by the United Nations Development Programme (UNDP) to measure and compare human development across countries. It assesses three key dimensions:
Health - Measured by life expectancy at birth.
Education - Measured by mean years of schooling and expected years of schooling. Standard of Living - Measured by Gross National Income (GNI) per capita (PPP in USD). The HDI ranges from 0 to 1, with higher values indicating better human development. While HDI provides a broad measure of well-being, it does not account for inequality, gender disparity, or environmental sustainability. The 2023-24 Human Development Report (HDR), titled "Breaking the Gridlock: Reimagining Cooperation in a Polarised World," ranks India 134th on the Human Development Index (HDI), while Switzerland tops the list.

Q2729. Which one of the following statements about a Money Bill is not correct?
Explanation
Statement (a) is incorrect: A Money Bill can only be introduced in the Lok Sabha on the prior recommendation of the President, as per Article 109 of the Indian Constitution. It cannot be introduced in the Rajya Sabha. Statement (b) is correct: The Speaker of the Lok Sabha is the final authority to decide whether a bill is a Money Bill or not. This decision is final and cannot be questioned in any court.

Statement (c) is correct: After the Lok Sabha passes the Money Bill, it is sent to the Rajya Sabha. The Rajya Sabha has 14 days to either accept, reject, or recommend changes in the bill to the Lok Sabha. The Lok Sabha can either accept or reject all or any of the recommendations of the Rajya Sabha. Statement (d) is correct: Once the Money Bill has been passed by the Lok Sabha (and the Rajya Sabha, if applicable), it is sent to the President for approval. The President may either give or withhold his assent to a Money Bill. The President cannot return a Money Bill to the Lok Sabha for reconsideration.

Explanation
Option (d) is correct: The speaker of the Lok sabha can ask a member of the house to stop speaking and let another member speak. It is known as yielding the floor. Yielding the floor allows the smooth and orderly conduct of debate in the House. The Speaker may ask a member to stop speaking if they have exceeded their time or if another member is to speak on the matter at hand. Options (a), (b) and (c) are incorrect:
Decorum refers to the appropriate behavior and conduct expected in the House. Crossing the floor is a term used when a member switches allegiance from one party to another, particularly in the context of voting or support. Interpellation is a formal procedure where a member of the House asks a question to the government, which requires a written or oral response. The term "interpellation" is not formally used in Indian parliamentary practice.
