Q742. Which distinctive geographical feature is formed at the mouth of the Mississippi River system?
Explanation
The Mississippi River is well-known for its unique depositional feature at its mouth in the Gulf of Mexico. This structure is classified as a bird’s-foot delta, characterized by long, narrow distributary channels that extend into the sea like the digits of a bird’s foot. This shape results from the heavy sediment load being deposited into relatively calm waters.
Q743. What are the three foundational dimensions of the Human Development Index?
Explanation
The framework for assessing human progress centers on three fundamental areas of life. These include the ability to lead a long and healthy existence, the opportunity to acquire knowledge through schooling, and the attainment of a decent standard of living. By combining these factors, the index provides a more comprehensive view of development than purely financial or infrastructure-based national metrics.
Q744. Which component of the Central Processing Unit (CPU) is responsible for directing and coordinating most of the operations in the computer?
Explanation
The Control Unit serves as the primary coordinator within the Central Processing Unit, managing the flow of data and instructions. It interprets commands from the computer’s memory and directs other components, such as the ALU and input/output devices, on how to respond. This vital function ensures that all hardware operations are executed in the correct sequence and timing.
Q745. Consider the following statements regarding the epigraphic sources of Rajasthan:
I. Prashastis are eulogistic inscriptions praising the achievements of rulers.
II. Copper plates (Tamrapatras) were primarily used to record land grants and religious donations.
III. All inscriptions in Rajasthan prior to the 10th century AD were written exclusively in the Apabhramsha language.
Which of the above statement(s) is/are correct?
I. Prashastis are eulogistic inscriptions praising the achievements of rulers.
II. Copper plates (Tamrapatras) were primarily used to record land grants and religious donations.
III. All inscriptions in Rajasthan prior to the 10th century AD were written exclusively in the Apabhramsha language.
Which of the above statement(s) is/are correct?
Explanation
Prashastis were eulogistic inscriptions composed by court poets to glorify the military and personal achievements of rulers. Copper plates, or Tamrapatras, served as formal legal documents recording land grants and religious endowments. Although many early inscriptions were in Sanskrit or Prakrit, the claim that all were written exclusively in Apabhramsha before the tenth century is historically inaccurate.
Q746. Which of the following is the correct sequence of political units in the Early Vedic period, arranged from the smallest to the largest?
Explanation
The political structure of the Early Vedic period was organized hierarchically based on kinship. The Kula or family was the basic unit, followed by the Grama or village. Multiple villages formed a Vis, and a collection of Vis constituted the Jana or tribe. The Rashtra emerged as the largest territorial entity, representing the collective identity of the tribal group.
Q747. Find the odd one out regarding the writs issued under Article 32:
Explanation
Article 32 empowers the Supreme Court to issue five specific types of writs for the enforcement of Fundamental Rights. These include Habeas Corpus, Mandamus, Prohibition, Certiorari, and Quo Warranto. An injunction is a general legal remedy used in civil law but is not one of the five prerogative writs traditionally listed under the constitutional remedies article.
Q748. Consider the following statements regarding the Siberian river systems:
I. The Ob, Yenisei, and Lena all flow predominantly northwards.
II. They discharge their waters into the Arctic Ocean.
III. Their lower reaches freeze in winter, leading to severe spring flooding when the upper reaches thaw.
IV. They are characterized by warm waters supporting tropical biodiversity.
Which of the above statement(s) is/are correct?
I. The Ob, Yenisei, and Lena all flow predominantly northwards.
II. They discharge their waters into the Arctic Ocean.
III. Their lower reaches freeze in winter, leading to severe spring flooding when the upper reaches thaw.
IV. They are characterized by warm waters supporting tropical biodiversity.
Which of the above statement(s) is/are correct?
Explanation
The major Siberian rivers, including the Ob, Yenisei, and Lena, primarily flow in a northward direction. These systems discharge their waters into the Arctic Ocean. A significant geographical challenge occurs during spring when the upper southern reaches thaw while the lower northern reaches remain frozen. This blockage leads to severe ice-jam flooding across the vast Siberian plains.
Q749. Which of the following is NOT an indicator used to measure the dimensions of the Human Development Index?
Explanation
To calculate human development, specific indicators are used for health, education, and wealth. Life expectancy represents the health dimension, while schooling years measure knowledge. National income per capita reflects the standard of living. Although infant mortality is a significant health concern, it is not a direct component in the primary calculation, as life expectancy already captures general survival trends.
Q750. Consider the following statements regarding Random Access Memory (RAM):
I. It is a volatile memory.
II. It directly communicates with the CPU.
III. It permanently stores the BIOS instructions.
Which of the above statement(s) is/are correct?
I. It is a volatile memory.
II. It directly communicates with the CPU.
III. It permanently stores the BIOS instructions.
Which of the above statement(s) is/are correct?
Explanation
Random Access Memory is characterized as volatile memory because it loses all stored data when the power is removed. It facilitates high-speed data exchange by communicating directly with the CPU during active processing. However, RAM does not store BIOS instructions permanently; that function is reserved for non-volatile ROM chips, which retain firmware even when the computer is off.Answer key for these questions
