Q1181. Read the following statements carefully: Statement I: A Gini Coefficient of 0 represents perfect income equality within a population. Statement II: A Gini Coefficient of 1 indicates absolute income inequality, where a single individual holds all the income. Which of the following is correct?
Explanation
On the scale used to measure inequality, a value of zero represents the theoretical ideal where every person has the exact same amount of income. Conversely, a value of one indicates a situation where a single person holds all the income while everyone else has none. Most nations fall somewhere in between, with lower numbers representing more egalitarian societies and resources.

Q1182. Which of the following is not considered a biometric security measure?
Explanation
Biometric security measures utilize unique physical or behavioral characteristics of an individual for authentication, such as fingerprints, retina patterns, or facial features. These methods are highly secure as they are difficult to replicate. In contrast, complex password generation is a traditional knowledge-based security method. While important for protecting accounts, passwords rely on something a user knows rather than their inherent biological.

Q1183. Consider the following coins: I. Akhayshai (Jaisalmer) II. Vijayashahi (Jodhpur) III. Jharshahi (Jaipur) IV. Madanshahi (Jhalawar) Which of the following is the correct sequence of their respective issuing states from West to East geographically?
Explanation
Arranging these coins by their issuing states from west to east follows the geography of Rajasthan. Jaisalmer (Akhayshai) is the westernmost, followed by Jodhpur (Vijayashahi) in the central-west. Jaipur (Jharshahi) is located towards the east, and Jhalawar (Madanshahi) is in the southeastern region. This geographical progression highlights the distribution of independent monetary centers across the various princely states of Rajasthan.

Q1185. Geometrically, the Gini Coefficient is calculated as the ratio of the area between the Lorenz curve and the line of perfect equality to the:
Explanation
To calculate the numerical measure of inequality, economists look at the space between the actual distribution curve and the line of perfect equality. This area is then divided by the total triangular area located below that diagonal line. This ratio provides a precise mathematical value that represents how far a society is from an even distribution of wealth or income.

Q1186. Match List I with List II.
Cyber Threat
Description
A. Worm
i. Fraudulent emails seeking sensitive data
B. Spyware
ii. Self-replicating malware requiring no host file
C. Phishing
iii. Malicious code inserted into a database query
D. SQL Injection
iv. Software that secretly monitors user activity
Explanation
Cyber threats take many forms, each with specific characteristics. Worms are self-replicating malware, while spyware secretly monitors user activity. Phishing uses deceptive emails to steal data, and SQL injection involves inserting malicious code into database queries. Recognizing these different attack vectors is essential for developing comprehensive cybersecurity protocols and protecting sensitive data from unauthorized access or malicious interference.

Q1187. Which of the following inscriptions provides the genealogy of the Rathores of Marwar up to Rao Siha?
Explanation
The Bithu Inscription, dated 1273 AD, is a critical source for the early history of the Rathores of Marwar. It records the death of Rao Siha, the founder of the Rathore dynasty in the region. This inscription provides the earliest authentic evidence regarding the migration and establishment of the Rathores in western Rajasthan, serving as a foundational record for their later genealogical and political expansion.

Q1188. Consider the following statements regarding the right against self-incrimination under Article 20(3): I. It extends to both oral evidence and documentary evidence. II. It extends to the compulsory production of material objects or blood specimens. III. It applies only to criminal proceedings, not to civil proceedings. Which of the above statement(s) is/are correct?
Explanation
The right against self-incrimination under Article 20(3) covers both oral and documentary evidence and applies only to criminal proceedings. It does not cover the compulsory production of material objects or blood specimens, so II is wrong.

Q1189. Consider the following statements regarding the Gini Coefficient: I. It can be used to measure both income inequality and wealth inequality. II. A decreasing Gini Coefficient indicates that income distribution is becoming more unequal. III. It satisfies the principle of anonymity, meaning it does not matter who the high and low earners are. IV. It is derived directly from the Lorenz curve. Which of the above statements are correct?
Explanation
Derived from a graphical distribution curve, this coefficient can measure disparities in both income and wealth. It follows the principle of anonymity, focusing on the overall distribution rather than specific individuals. Importantly, as the value of the coefficient decreases, it indicates that the distribution is becoming more equal over time, reflecting a reduction in the concentration of resources.

Q1190. Given below are two statements regarding digital authentication. Statement I: A digital signature provides authenticity and non-repudiation of an electronic document. Statement II: Digital signatures rely on hash functions and public key cryptography. Which of the above statement(s) is/are correct?
Explanation
Digital signatures provide a powerful way to ensure the authenticity and integrity of electronic documents. By using public-key cryptography and hash functions, they verify the identity of the sender and confirm that the document has not been altered since it was signed. This technology supports non-repudiation, meaning the signer cannot later deny having signed the document, which is vital.
