UPSC Editorials Quiz : 10 August 2024

Introducing QUED – Questions from Editorials (UPSC Editorials Quiz) , an innovative initiative from InsightsIAS. Considering the significant number of questions in previous UPSC Prelims from editorials, practicing MCQs from this perspective can provide an extra edge. While we cover important editorials separately in our Editorial Section and SECURE Initiative, adding QUED (UPSC Editorials Quiz) to your daily MCQ practice alongside Static Quiz, Current Affairs Quiz, and InstaDART can be crucial for better performance. We recommend utilizing this initiative to enhance your preparation, with 5 MCQs posted daily at 11 am from Monday to Saturday on our website under the QUIZ menu.

• Question 1 of 5 1. Question Matarbari Port is an under-construction sea-port, located in a) Newton's Third Law b) Pascal's Law c) Archimedes' Principle d) Bernoulli's Principle Correct Solution: d) Bernoulli’s Principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy. In the context of aircraft wings, the faster-moving air over the curved top surface creates a lower pressure compared to the bottom surface. This pressure difference generates lift, allowing the aircraft to overcome gravity and achieve flight. This principle is fundamental to understanding how aircraft wings create the necessary force for takeoff and sustained flight.

• a) Newton's Third Law

• b) Pascal's Law

• c) Archimedes' Principle

• d) Bernoulli's Principle

Solution: d)

Bernoulli’s Principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy. In the context of aircraft wings, the faster-moving air over the curved top surface creates a lower pressure compared to the bottom surface. This pressure difference generates lift, allowing the aircraft to overcome gravity and achieve flight.

• Question 3 of 5 3. Question Consider the following statements in the context of Temperature effects on aircraft performance STATEMENT 1: Higher temperatures reduce air density. STATEMENT 2: Hot air improves engine combustion. Which of the statements above is/are correct? a) Only STATEMENT 1 b) Only STATEMENT 2 c) BOTH STATEMENTS d) Neither statements Correct Solution: a) STATEMENT 1 EXPLANATION: Increased temperatures cause air to expand, resulting in lower air density. This means fewer air molecules are available to generate lift and support combustion in engines. STATEMENT 2 EXPLANATION: This statement is false. In reality, hotter, less dense air negatively affects engine combustion due to fewer oxygen molecules available to mix with fuel, reducing engine power and efficiency. Incorrect Solution: a) STATEMENT 1 EXPLANATION: Increased temperatures cause air to expand, resulting in lower air density. This means fewer air molecules are available to generate lift and support combustion in engines. STATEMENT 2 EXPLANATION: This statement is false. In reality, hotter, less dense air negatively affects engine combustion due to fewer oxygen molecules available to mix with fuel, reducing engine power and efficiency.

• Question 4 of 5 4. Question Consider the following statements. India’s current mineral resource classification rules largely based on the United Nations Framework Classification for Resources (UNFC). Most mining companies, stock exchanges, and regulatory bodies across the world adhere to the Committee for Mineral Reserves International Reporting Standards (CRIRSCO) template. United Nations Framework Classification for Resources (UNFC) provides sufficient information to determine the economic viability of mining a mineral block. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Statement 3 is incorrect. The Ministry of Mines was forced to scrap the auction for the lithium block in Jammu and Kashmir’s (J&K’s) Reasi district for the second time, following weak investor response. According to experts, India’s current resource classification rules largely based on the United Nations Framework Classification for Resources (UNFC) do not provide sufficient information to determine the economic viability of mining a mineral block. Clarity on the economic viability of mining lithium is especially important as the extraction process is expensive, and with global lithium prices falling significantly over the past few months, miners are increasingly eager to maintain their margins. Most mining companies, stock exchanges, and regulatory bodies across the world adhere to the Committee for Mineral Reserves International Reporting Standards (CRIRSCO) template, instead of the UNFC one, which requires the reporting of economically viable reserves with high geological confidence confirmed through studies to at least a pre-feasibility level. Mining experts say that to attract private investment in the sector, India should adopt CRIRSCO-aligned internationally-compliant mineral reporting standards.

• Question 5 of 5 5. Question Consider the following statements in the context of Aerospace applications of 3D printing STATEMENT 1: 3D printing is primarily used for large fuselage sections. STATEMENT 2: Additive manufacturing cannot produce high-value aerospace components. Which of the statements above is/are correct? a) Only STATEMENT 1 b) Only STATEMENT 2 c) BOTH STATEMENTS d) Neither statements Correct Solution: d) STATEMENT 1: While 3D printing is used in aerospace manufacturing, it is not primarily used for large fuselage sections. These components are typically manufactured using traditional methods like aluminum forming or composite layup due to their size and structural requirements. STATEMENT 2: This statement is incorrect. Additive manufacturing is capable of producing high-value aerospace components. In fact, its ability to create complex geometries and optimize material usage makes it particularly suitable for manufacturing high-value, performance-critical parts in the aerospace industry. The National Sample Survey Office (NSSO), Ministry of Statistics and Programme Implementation has conducted Household Consumption Expenditure Survey (HCES). This survey on household consumption expenditure aims at generating estimates of household Monthly Per Capita Consumption Expenditure (MPCE) and its distribution separately for the rural and urban sectors of the country, for States and Union Territories, and for different socio-economic groups. The Household Consumption Expenditure Survey (2022-23) has highlighted significant nutritional deficiencies among India’s poor.
