This landmark amendment ensures that daughters, along with sons and their mothers, are entitled to an equal share of family property. The act aimed to eliminate gender discrimination in property inheritance, promoting equality within Hindu families.
Question 5: A sound plan of action is necessary for the conversation of forests. What steps should this plan take?
- Protection of animals at highest tophic level, ie., top carnivores, as they depend directly on herbivores (Correct answer)
- Protection of herbivores
- Comprehensive programme for the protection of all the physical and biological components of forests
- Protection of consumers
Correct answer: Protection of animals at highest tophic level, ie., top carnivores, as they depend directly on herbivores
Protecting animals at the highest trophic level, such as top carnivores, is a crucial strategy in forest conservation because they act as indicator species and play a vital role in maintaining ecosystem balance. Their survival depends on a healthy population of prey (herbivores) and intact habitats, meaning their protection indirectly ensures the conservation of lower trophic levels and the overall forest ecosystem. This 'top-down' approach helps regulate herbivore populations, preventing overgrazing and promoting forest regeneration.
Question 6: Which of the following is a sunrise industry example?

A sunrise industry is characterized by rapid growth, high innovation, and significant future potential, often driven by new technologies or changing consumer demands. The Information Technology (IT) industry perfectly fits this description, having experienced explosive growth and continuous innovation globally. In contrast, paper, cooking oil, and jute industries are generally considered mature or traditional sectors with slower growth rates.
Question 7: Work is completed at a rate known as:
- Power (Correct answer)
- Force
- Energy
- Motion
Correct answer: Power
Power is defined as the rate at which work is done or energy is transferred. It quantifies how quickly work is performed, meaning a higher power output indicates more work being completed in a shorter amount of time. Force is a push or pull, energy is the capacity to do work, and motion is the change in position, none of which directly describe the rate of work.
Question 8: Caterpillar secretions of the following species are used to make tussar silk:
- Antheraea mylitta (Correct answer)
- Bombyx mori
- Anteraea assama
- Attacus ricinni
Correct answer: Antheraea mylitta
Tussar silk, also known as Kosa silk, is a type of wild silk primarily produced from the larvae of the silk moth species *Antheraea mylitta*. Unlike mulberry silk, which comes from domesticated silkworms, tussar silk moths feed on specific trees in the wild. Their cocoons are collected from forests, particularly in India, to extract the unique, coarser silk fibers.
Question 9: What do we call the process when the enslavement of one nation by another results in political, economic, social, and cultural changes?
- Confederacy
- Renaissance
- Mercantile
- Colonization (Correct answer)
Correct answer: Colonization
Colonization is the process by which one nation establishes political, economic, and social control over another territory, often distant, and its people. This process inherently leads to profound and often coercive changes in the subjugated nation's political structures, economic systems, social hierarchies, and cultural practices, as the colonizer imposes its own systems and values.
Question 10: Which of the following options does a bar diagram best reflect the data on?
- Temperature
- Rainfall (Correct answer)
- Air pressure
- Humidity
Correct answer: Rainfall
Bar diagrams are highly effective for displaying and comparing discrete categories of data, such as rainfall totals over different months, years, or regions. Each bar represents a specific category, and its height or length corresponds to the value of the data, making it easy to visualize and compare variations in rainfall patterns. This visual representation clearly highlights differences across categories.
Question 11: Which of the following best describes the biosphere?
- Man's immediate surroundings
- Plant and animal kingdom
- Various domains of environment

This regulation aimed to ensure financial transparency and accountability among those holding public office, preventing corruption and mismanagement.
Question 15: A kilowatt-hour is a measure of -
- Electric charge
- Power
- Electric current
- Energy (Correct answer)
Correct answer: Energy
A kilowatt-hour (kWh) is a standard unit of energy, specifically used to measure electrical energy consumption. It represents the amount of energy consumed by a device with a power of one kilowatt operating for one hour. While power is the rate of energy consumption, the kilowatt-hour measures the total *quantity* of energy used over time, making it a common unit for billing electricity.
Question 16: Which of the following oxides will turn blue litmus red in an aqueous solution?
- Magnesium oxide
- Iron Oxide
- Sulphur dioxide
- Copper oxide
Blue litmus paper turns red in the presence of an acidic solution. Among the given options, sulphur dioxide (SO2) is an acidic oxide, as it is formed from a non-metal. When sulphur dioxide dissolves in water, it forms sulfurous acid (H2SO3), which is acidic and will cause blue litmus to turn red. The other options (magnesium oxide, iron oxide, copper oxide) are metal oxides, which are typically basic.
