Explanation

The Reserve Bank of India (RBI) is primarily responsible for maintaining price stability and controlling inflation in India. It does this through its monetary policy framework, which includes tools like the repo rate, reverse repo rate, open market operations, and cash reserve ratio (CRR). Under the Monetary Policy Framework Agreement (2016), the RBI, in collaboration with the Government of India has a mandate to maintain inflation at 4% (with a tolerance band of ±2%), i.e., between 2% to 6%.

Explanation

Statement 1 is correct: The election date of the Deputy Speaker of Lok Sabha is not fixed in the Constitution. However, according to Rule 8 of the Rules of Procedure and Conduct of Business in Lok Sabha, The Speaker decides the date of election of the Deputy Speaker. The election usually happens after the Speaker’s election, but there is no constitutional or statutory time limit for it.

Statement 2 is incorrect: There is no such mandatory provision that the election of a candidate, as Deputy Speaker of Lok Sabha, shall be from either the principal opposition party or the ruling party. It is only by convention that the position of Deputy Speaker is offered to the opposition party in India.

Statement 3 is correct: In case of the absence of the Speaker, the Deputy Speaker presides over the sessions of the Lok Sabha and conducts the business in the house, during such time he/she enjoys the same power as the Speaker when presiding over the sitting of the House.

Statement 4 is incorrect: The appointment of the Deputy Speaker of the Lok Sabha is not initiated by the Speaker. Instead, a member of the Lok Sabha moves the motion for the election, which is then put to vote in the House. While the ruling party historically held this position, in recent decades, a convention has developed of electing a member from the opposition. There is no rule or convention requiring the Prime Minister to second the motion, and any member of the House may do so.

Explanation

Statement 1 is incorrect: The proclamation of Emergency must be approved by both the Houses of Parliament within one month from the date of its issue. If approved by both the Houses of Parliament, the emergency continues for six months, and can be extended to an indefinite period with an approval of the Parliament for every six months.

Statement 2 is correct: A No-Confidence Motion can only be initiated and passed in the Lok Sabha (House of the People). The Rajya Sabha (Upper House) cannot move or pass a No-Confidence Motion against the government.

Statement 3 is incorrect: As per Article 61, when a President is to be impeached for violation of the Constitution, the charges can be initiated by either House of Parliament. The impeachment resolution needs to be passed by not less than a majority of two-thirds of the total membership in each house.

Explanation

Statement 1 is incorrect: The constitution mentions the word ‘council of ministers’, however it doesn’t classify ministers into 4 categories. Generally, the Prime Minister and other Ministers are collectively known as the Council of Ministers.

Statement 2 is correct: As per 91st Constitutional Amendment Act, the total number of Central Council of Ministers/State Council of Ministers including Prime Minister/ Chief Minister should not be more than 15% of total strength of Lok Sabha. It aimed at curbing the growing size of Cabinets at both the Union and State levels, which had often led to inefficient governance, excessive expenditure, and political instability. The goal was to promote good governance, encourage coalition politics, and reduce the influence of "buying loyalty" by offering ministerial positions.

Explanation

The Fractional Orbital Bombardment System (FOBS) is a missile technology designed to place a nuclear warhead into a partial Earth orbit before deorbiting to strike a target. Unlike intercontinental ballistic missiles (ICBMs), FOBS takes an unpredictable orbital path, bypassing traditional radar systems and potentially striking from unexpected directions, such as via the South Pole. Originally developed by the Soviet Union in the 1960s, FOBS was tested with the R-36ORB missile but later abandoned under arms control treaties like SALT II and the Outer Space Treaty. Recent reports indicate renewed interest, with countries like China reportedly testing FOBS integrated with hypersonic glide vehicles. Its capability to evade missile defenses has raised global security concerns and spurred advancements in countermeasures.

Explanation

A biofilm is a collection of microbial cells that are encased in a polysaccharide-based matrix and are permanently attached to a surface (i.e., cannot be removed by gentle rinsing). Microorganisms that form biofilms include bacteria, fungi, and protists. Noncellular materials such as mineral crystals, corrosion particles, clay or silt particles, or blood components, depending on the environment in which the biofilm has developed, may also be found in the biofilm matrix.

Statement 1 is correct: Biofilms may form on a wide variety of surfaces, including living tissues, food and food processing surfaces, indwelling medical devices (devices in the body like catheters, heart valves), human and animal tissue, industrial or potable water system piping, or natural aquatic systems.

Statement 2 is correct: Biofilms are a significant concern in the food industry, forming on surfaces such as cutting boards, conveyor belts, and food packaging equipment. Contaminated biofilms can lead to foodborne illnesses caused by pathogens like Listeria monocytogenes, Salmonella, and Escherichia coli.

Statement 3 is correct: Microorganisms in biofilms are significantly more resistant to antibiotics compared to planktonic (free-floating) cells because:

The EPS (extracellular polymeric substance) matrix acts as a barrier, limiting antibiotic penetration. Cells within biofilms have reduced metabolic activity, making them less susceptible to antibiotics targeting active processes. Some bacteria within biofilms can exchange antibiotic resistance genes via horizontal gene transfer. This resistance complicates treatment, especially in chronic infections such as cystic fibrosis, where Pseudomonas aeruginosa biofilms are common.

Explanation

Miyawaki method is a method of urban afforestation by turning backyards into mini-forests. It includes planting trees as close as possible in the same area which not only saves space, but the planted saplings also support each other in growth and block sunlight from reaching the ground, thereby preventing the growth of weeds. Thus the saplings become maintenance-free (self-sustainable) after the first three years. It helps to create a forest in just 20 to 30 years while through conventional methods it takes anywhere between 200 to 300 years. In the Miyawaki Process:

The native trees of the region are identified and divided into four layers -- shrub, sub-tree, tree, and canopy. The quality of soil is analysed and biomass which would help enhance the perforation capacity, water retention capacity, and nutrients in it, is mixed with it. The ground is covered with a thick layer of mulch. A mound is built with the soil and the seeds are planted at a very high density -- three to five sapling per square meter.

Explanation

Wetlands Location and Significance Hokera Wet-land Jammu and Kashmir. A perennial natural wetland that is part of the Jhelum basin. Renuka Wet-land Himachal Pradesh A naturally occurring wetland that receives freshwater springs and underground karst formations from the lower Himalayas and the Giri river. Rudrasagar lake Melaghar, Tripura A lowland sedimentation reservoir in the northeastern highlands that receives water from three enduring streams that empty into the River Gomti. Sasthamkotta lake Kollam district, Kerala Being Kerala’s largest freshwater lake, it has long been a popular destination for travellers.

Explanation

Natural wetlands are often called "earth’s kidneys" because they effectively filter pollutants from water, much like our kidneys filter waste and excess fluid from our bodies. Just as kidneys maintain a healthy balance of water, salts, and minerals, wetlands absorb and store excess nutrients, heavy metals, and chemicals from runoff. Aquatic plants and microorganisms help absorb heavy metals, excess nutrients, while sediment settles at the bottom in areas of slow-moving water, preventing it from reaching open water.
