Creating local bodies
- B.
Financial decentralization
- C.
People's participation in policy making
- D.
None of the above
Correct Answer
B. Financial decentralizationExplanation
Mayo's Resolution of 1870 aimed to achieve financial decentralization. This means that the objective was to distribute financial power and decision-making authority to local bodies or entities. By doing so, it would allow for more local control and management of financial resources, promoting autonomy and accountability at the local level. This approach would also enable better allocation of funds and resources based on the specific needs and priorities of each locality.Rate this question:

- A.
Both I & III
- B.
Both I & II
- C.
Both II & III
- D.
All the above
Correct Answer
A. Both I & IIIExplanation
The drawbacks of local bodies formed during British rule were limited franchise and the fact that municipalities were headed by non-officials. Limited franchise means that only a small portion of the population had the right to vote or participate in local governance. This restricted the representation and voice of the people. Additionally, having non-officials as the heads of municipalities meant that there was no proper control and management by the government, leading to potential mismanagement and corruption. Therefore, the correct answer is Both I & III.Rate this question:

Steel is more elastic than rubber because it -
- A.
Is harder than rubber
- B.
Requires larger deforming force
- C.
Is never deformed
- D.

Correct Answer
B. Requires larger deforming forceExplanation
Steel is more elastic than rubber because it requires a larger deforming force. Elasticity refers to a material's ability to deform under stress and return to its original shape when the stress is removed. Steel, being a stronger and more rigid material compared to rubber, requires a greater force to deform it. On the other hand, rubber is known for its high elasticity as it can easily deform under smaller forces. Therefore, steel's higher elasticity is attributed to the fact that it requires a larger deforming force.Rate this question:

Price rigidity is the feature of -
- A.
Perfect competitive competition
- B.
Monopoly
- C.
Oligopoly
- D.
Monopolistic competition
Correct Answer
C. OligopolyExplanation
Price rigidity is a characteristic of oligopoly. In an oligopoly market structure, there are only a few large firms that dominate the market. Due to the interdependence of these firms, they tend to engage in strategic behavior and closely monitor each other's pricing decisions. This leads to a situation where prices are relatively stable and resistant to change, resulting in price rigidity. In contrast, perfect competition, monopoly, and monopolistic competition do not exhibit the same level of price rigidity as they have different market structures and characteristics.Rate this question:

The surface of a lake is frozen in severe winter, but the water at its bottom is still liquid. What is the reason?
- A.
Ice is a bad conductor of heat
- B.
Since the surface of the lake is at the same temperature as the air, no heat is lost
- C.
The density of water is maximum at 4°C
- D.
None of the above
Correct Answer
C. The density of water is maximum at 4°CExplanation
The reason why the surface of a lake is frozen in severe winter, but the water at its bottom is still liquid is because the density of water is maximum at 4°C. As the temperature decreases, the water near the surface starts to cool and become denser. This denser water sinks to the bottom, displacing the warmer water which rises to the surface. This process continues until the entire lake is at a uniform temperature of 4°C, which is the temperature at which water is most dense. As a result, the bottom water remains in liquid form while the surface freezes.Rate this question:

When a person climbs a hill, bending forward helps to increase stability. This is because it shifts the center of gravity lower and closer to the ground, providing a better balance and preventing the person from losing their balance and falling backwards. By leaning forward, the person can distribute their weight more evenly and maintain a stable position while climbing uphill.Rate this question:

A football bounces when it falls on the ground, because -
- A.
It is made up of Rubber
- B.
It is hollow
- C.
It is very light and is able to overcome the resistance of air
- D.
Of its property of elasticity
Correct Answer
D. Of its property of elasticityExplanation
When a football falls on the ground, it bounces due to its property of elasticity. Elasticity refers to the ability of an object to regain its original shape after being deformed. In the case of a football, when it hits the ground, it gets compressed. However, because of its elasticity, it quickly regains its original shape, causing it to bounce back up. This property allows the football to overcome the resistance of the ground and gravity, resulting in a bouncing motion.Rate this question:

An air bubble in water will act like a -
- A.
Convex mirror
- B.
Concave lens
- C.
Concave mirror
- D.
Convex lens
Correct Answer
D. Convex lensExplanation
An air bubble in water will act like a convex lens because it has a curved surface that is thicker in the middle and thinner at the edges. This curvature causes light rays passing through the bubble to converge, similar to how a convex lens focuses light. As a result, the image formed by the bubble will be smaller and inverted.Rate this question:

Superconductivity means -
- A.
Very feeble currect
- B.
Very large current
- C.
Current without facing any resistance
- D.
Current due to positive particles
Correct Answer
C. Current without facing any resistanceExplanation
Superconductivity refers to the phenomenon where an electric current can flow through a material without experiencing any resistance. This means that the current can move through the material indefinitely without losing any energy. In superconducting materials, the electrons pair up and move together, creating a current that can flow freely without any obstacles. This property allows for the efficient transmission of electricity and has various applications in industries such as healthcare, energy, and transportation.Rate this question:

In photoelectric emission, the energy of emitted electron is
- A.
Same as that of incident photon
- B.
Larger than that of incident photon
- C.
Less than that of incident photon
- D.
Proportional to the intensity of incident light
Correct Answer
D. Proportional to the intensity of incident lightExplanation
In photoelectric emission, the energy of the emitted electron is proportional to the intensity of the incident light. This means that as the intensity of the incident light increases, the energy of the emitted electron also increases. This is because the energy of the incident photons is transferred to the electrons, causing them to be emitted from the material. The greater the intensity of the incident light, the more energy is transferred to the electrons, resulting in higher energy electrons being emitted.Rate this question:
