A district administration in a major horticulture-producing belt is evaluating a draft policy to reduce severe post-harvest losses among small and marginal farmers. The initial proposal suggests providing a 50% capital subsidy to private logistics firms to construct a single centralized mega-cold storage facility at the district headquarters. However, a feasibility study reveals two major bottlenecks: small farmers in remote blocks cannot afford the high freight costs to transport produce to the central hub, and small-scale private operators still lack sufficient capital despite the subsidy. As the District Magistrate tasked with optimizing policy feasibility and social impact, which of the following policy modifications is the most administratively viable and effective option?

A coastal state administration is formulating an Urban Drainage and Flood Risk Mitigation Policy for a densely populated port city that suffers from severe monsoon waterlogging due to heavy plastic clogging in major urban canals. The administration aims to ensure immediate operational efficiency, administrative feasibility, and socio-economic sustainability without causing public distress. Which of the following measures represent administratively feasible and sustainable policy interventions for the state administration to implement?

Six administrative officers—Aarav, Bina, Chetan, Divya, Ekta, and Farhan—belong to three departments: Agriculture, Defense, and Commerce, with exactly two officers per department. They are allocated into two three-member scrutiny committees, Committee 1 and Committee 2, such that each committee contains exactly one representative from each department. Each officer holds one of two designations: Senior Advisor or Junior Advisor.

The allocation follows these analytical rules:
1. Aarav and Farhan belong to the same department (which is not Defense), but are assigned to different committees.
2. Bina and Chetan are the only two officers representing the Defense department, and Bina is assigned to Committee 1.
3. Ekta and Farhan are Senior Advisors, whereas Bina and Divya are Junior Advisors.
4. The Commerce department consists of exactly one Senior Advisor and one Junior Advisor.
5. Chetan and Divya are assigned to the same committee.
6. Aarav is a Junior Advisor, and the Agriculture department officer assigned to Committee 2 is a Senior Advisor.

Based on the above constraints, which officer represents the Agriculture department in Committee 1, and what is their designation?

Four research scholars—Ananya, Bharath, Chitra, and Deepak—are to be divided into two project teams, Team Alpha and Team Beta, with exactly two members in each team. The distribution must follow these rules:
1. Ananya and Bharath cannot be in the same team.
2. Chitra must be assigned to Team Alpha.

Based on these rules, which of the following statements are correct?

During severe midnight rainfall, a Sub-Divisional Magistrate (SDM) receives news of a critical structural failure risk in a major river barrage upstream of a densely populated valley. Primary telecommunication lines are disrupted, and water levels are rising rapidly. Local community leaders demand that the SDM order an immediate breach of an adjacent downstream embankment to divert floodwaters toward uninhabited farmland, even though this breach would bypass statutory engineering assessments and threaten unauthorized inundation of neighboring low-lying hamlets. According to established disaster response and administrative management protocols, which course of action should the SDM prioritize?

As the District Magistrate serving as the Chairperson of the District Disaster Management Authority (DDMA), you are informed of a major rupture in a high-pressure industrial chemical pipeline carrying toxic, flammable gas adjacent to a densely populated township. The toxic plume is advancing rapidly toward residential sectors, and mass panic has caused severe traffic gridlock along the designated primary evacuation highway. Concurrently, the plant's management proposes immediately flushing the remaining volatile chemical inventory into an adjoining river—a direct violation of environmental protection laws—claiming it is the only way to prevent a catastrophic ground-level vapor cloud explosion. Which of the following represents the most legally sound, ethically responsible, and administratively effective immediate course of action?

A municipal administration is preparing a feasibility analysis for a new public policy aimed at reducing plastic waste contamination in urban waterways. Which of the following policy measures represent administrative actions that are legally compliant and socially feasible?

Just before sunset, Ananya starts walking from point $P$ directly towards her shadow. After walking $10\text{ m}$ to reach point $Q$, she turns $135^\circ$ anti-clockwise and walks $10\sqrt{2}\text{ m}$ to point $R$. From point $R$, she turns $90^\circ$ to her right and walks $15\sqrt{2}\text{ m}$ to point $S$. Finally, she turns to face South and walks $5\text{ m}$ to reach point $T$. What is the shortest straight-line distance between point $P$ and point $T$, and in which direction is point $T$ located relative to point $P$?

As the District Disaster Management Officer responding to an industrial toxic gas leak near a populated residential zone, arrange the following standard emergency response measures in the correct chronological sequence of operational priority.

A field researcher starts from a campsite and walks $10\text{ km}$ due North. She then turns right and walks $7\text{ km}$ due East. Next, she turns left and walks $6\text{ km}$ due North. Finally, she turns right and walks $5\text{ km}$ due East. What is the shortest straight-line distance (in km) from her final position to the campsite?

At sunset, a surveyor standing at point $O$ observes the shadow of a tall communication tower pointing directly towards point $A$. He walks $12\text{ m}$ straight along the shadow to reach point $A$. From point $A$, he turns $135^\circ$ clockwise and walks $10\sqrt{2}\text{ m}$ to reach point $B$. At point $B$, he takes a $90^\circ$ right turn and walks $5\sqrt{2}\text{ m}$ to point $C$. From point $C$, after turning $135^\circ$ anti-clockwise, he walks $15\text{ m}$ to reach point $D$. Finally, he turns to his left and walks $5\text{ m}$ to reach point $E$. What is the shortest distance from point $O$ to point $E$, and in which direction is point $E$ located relative to point $O$?

Complete the given number series by determining the missing term that logically fits the sequence.

A District Collector is tasked with resolving a severe public health crisis caused by toxic heavy metal contamination in downstream agricultural groundwater, linked to unauthorized industrial discharge upstream. Arrange the following administrative intervention steps in the logical sequence of qualitative cause-and-effect problem solving, starting from root-cause identification to long-term structural remediation.
