Explanation
The Deccan Plateau covers vast areas of southern and western India. It originated from massive fissure-type volcanic eruptions that deposited thick layers of basaltic lava. The weathering of these volcanic rocks produces rich, dark black soils known for moisture retention and suitability for cotton cultivation. Consequently, the description of the region as having light-colored, acidic sandy soil is scientifically inaccurate.Assertion (A): A high per capita income in a country does not necessarily imply a high level of human development.
Reason (R): Per capita income calculations do not account for income inequality, environmental degradation, or access to basic healthcare and education.
Explanation
High per capita income is an insufficient measure of human development because it overlooks several qualitative factors. While income provides the means for progress, it does not guarantee equitable access to education or healthcare. Additionally, it fails to capture environmental costs or social inequalities. Therefore, development requires a broader focus on human freedoms and basic needs rather than average wealth.Explanation
Newton’s first law of motion is widely recognized as the law of inertia. It states that an object will remain at rest or in uniform motion unless acted upon by an external force. This principle highlights the inherent resistance of matter to changes in its velocity. In contrast, the second law relates force to acceleration, while the third law concerns action and reaction.I. It is characterized by flake-based tools.
II. The Luni basin contains significant sites of this period.
III. Scrapers and points are the most common tool types.
IV. It corresponds to the Middle Pleistocene climatic phase.
V. Chert, jasper, and fine-grained quartzite were increasingly preferred over coarse rocks.
Which of the above statement(s) is/are correct?
Explanation
The Middle Palaeolithic in Rajasthan is characterized by flake-based tools, including scrapers and points, found extensively in the Luni basin. There was a notable shift toward using fine-grained materials like chert and jasper over coarse quartzite. While it represents a significant cultural phase, the association with a specific climatic stage must align with Upper Pleistocene data rather than Middle Pleistocene contexts.Explanation
Lothal, situated in Gujarat near the Gulf of Khambhat, was a vital port city of the Indus Valley Civilisation. Its most significant archaeological feature is an artificial brick dockyard, which was connected to the river Bhogavo. This structure facilitated maritime trade with other regions. Unlike other sites, Lothal also provided evidence of double burials in several grave pits.Explanation
Frank Anthony was a prominent leader of the Anglo-Indian community and represented them in the Constituent Assembly. He played a significant role in ensuring that the interests and rights of his community were protected within the new constitutional framework. Alongside others like Sir H. P. Modi representing Parsis, he helped make the assembly a truly representative body of India.I. Tibetan Plateau
II. Deccan Plateau
III. Katanga Plateau
IV. Patagonian Plateau
Select the correct order from the options given below:
Explanation
Geographic plateaus are distributed across different latitudes globally. The Tibetan Plateau is located in Central Asia, making it the northernmost in this list. Moving south, the Deccan Plateau occupies the Indian subcontinent. Further south, the Katanga Plateau is situated in Central Africa. Finally, the Patagonian Plateau is located at the southern tip of South America, completing the north-to-south sequence.I. Divide the real GDP by the total population.
II. Compile the total market value of all final goods and services produced in the current year.
III. Select a base year for price comparison.
IV. Apply the GDP deflator to adjust nominal GDP for inflation.
Which of the following represents the correct sequence?
Explanation
Calculating real per capita income begins with compiling nominal GDP data at current market prices. Next, a base year is selected to provide a constant price reference. The GDP deflator is then applied to adjust these nominal figures for inflation, resulting in real GDP. Finally, this real GDP is divided by the total population to find the final value.Explanation
An inertial frame of reference is a coordinate system that is either at rest or moving at a constant velocity. In such frames, Newton’s first law of motion remains valid, meaning objects experience no acceleration unless a net force is applied. Non-inertial frames are those that are accelerating or rotating, where fictitious forces appear and the standard laws of motion require modification.Answer key for these questions
