Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 14

Which of the following statements best describes the ‘head count ratio’?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 14
  • A common method used to estimate poverty in India is based on the income or consumption levels and if the income or consumption falls below a given minimum level, then the household is said to be Below the Poverty Line (BPL).
  • Poverty: According to the World Bank, Poverty is pronounced deprivation in well-being and comprises many dimensions. It includes low incomes and the inability to acquire the basic goods and services necessary for survival with dignity.
  • Poverty Line: The conventional approach to measuring poverty is to specify a minimum expenditure (or income) required to purchase a basket of goods and services necessary to satisfy basic human needs and this minimum expenditure is called the poverty line.
  • Poverty Line Basket: The basket of goods and services necessary to satisfy basic human needs is the Poverty Line Basket (PLB).
  • Poverty Ratio: The proportion of the population below the poverty line is called the poverty ratio or headcount ratio (HCR). Hence option (b) is the correct answer. 
Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 15

In order to arrive at the market price of the product, which of the following are added to the factor cost of the product?

1. Total direct taxes

2. Total indirect taxes

3. Total subsidies

Select the correct answer using the code given below.

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 15
  • Factor cost is the cost of an item of goods or a service in terms of the various factors which have played a part in its production or availability.
  • In order to arrive at the market prices, we have to add to the factor cost the total indirect taxes less total subsidies. Also, it does not generally include direct taxes. Hence option (b) is the correct answer.
  • Once goods and services are produced they are sold in a marketplace at a set market price. The market price is the price that consumers will pay for the product when they purchase it from the sellers. Taxes charged by the government will be added to the factor price while subsidies provided will be reduced from the factor price to arrive at the market price.
  • Taxes are added on because taxes are costs that increase the price, and subsidies are reduced because subsidies are already included in the factor cost, and cannot be double-counted when the market price is calculated. The market price will be decided, depending on the cost of production, demand for the product, and prices that are charged by competitors. In economics, the market price is identified as the price at which demand for the product or service is equal to its supply.
  • Changes in the levels of demand and supply, cost of factor inputs, and other economic and environmental conditions can affect the market price of a good or service. 
Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 16

Under which of the following types of unemployment more people are doing work than actually required?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 16
  • Disguised Unemployment
    • It is a situation in which more people are doing work than actually required. Even if some are withdrawn, production does not suffer. In other words, it refers to a situation of employment with surplus manpower in which some workers have zero marginal productivity. Hence option (b) is the correct answer.
    • Overcrowding in agriculture due to the rapid growth of the population and lack of alternative job opportunities may be cited as the main reasons for disguised unemployment in India.
    • Note:
      • Casual Unemployment: When a person is employed on a day-to-day basis, casual unemployment may occur due to short-term contracts, shortage of raw materials, fall in demand, change of ownership, etc.
      • Chronic Unemployment: If unemployment continues to be a long-term feature of a country, it is called chronic unemployment. The rapid growth of the population and inadequate level of economic development on account of the vicious circle of poverty are the main causes of chronic unemployment. 
Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 17

A decision of the Reserve Bank of India to increase the Cash Reserve Ratio (CRR) is most likely to result in

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 17
  • Cash Reserve Ratio (CRR) is the average daily balance that a bank is required to maintain with the Reserve Bank as a percent of its net demand and time liabilities (NDTL) as of the last Friday of the second preceding fortnight that the Reserve Bank may notify from time to time in the Official Gazette. 
  • Cash Reserve Ratio (CRR) = Percentage of deposits which a bank must keep as cash reserves with the bank.
  • CRR is one of the monetary policy tools that the RBI uses to control inflation. During high inflation in the economy, RBI increases the CRR to lower the bank’s loanable funds. Thus, when banks are required to deposit more cash with the RBI the total loanable funds with the banks will reduce. The less availability of funds with the banks will lead to an increase in the interest rates charged by the Banks. Hence, option (b) is the correct answer.
  • The rise in interest rates decreases the liquidity in the market which further seeks to reduce the aggregate demand and thereby inflation in the economy. Hence, options (a) and (c) are not correct.
  • A high-interest rate by the banks is likely to attract households to save more money with banks. Thus an increase in CRR is likely to increase household savings with the banks. Hence, option (d) is not correct.

In the context of the Balance of Payments, consider the following :

1. External commercial borrowing

2. Government transfers

3. Balance of invisibles

4. Global depository receipt

Which of the above comes under Capital Account ?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 21
  • The balance of payments (BOP), or the balance of international payments, is a statement of all transactions made between entities in one country and the rest of the world over a defined period, such as a quarter or a year. It summarizes all transactions of a country's individuals, companies, and government bodies, complete with individuals, companies, and government bodies outside the country. External Commercial borrowings refer to commercial loans in the form of bank loans, buyers’ credit, suppliers’ credit, and securitized instruments availed from non-resident lenders with a minimum average maturity of 3 years. They form a part of the Capital account in the context of the Balance of Payments. So, Statement 1 is correct.
  • Government transfers are usually in the form of gifts or grants, which do not have quid pro quo. This means that it need not be compensated or reciprocated. Once it is received, it need not be repaid. Hence, they form a part of the current account and not the capital account in the context of the Balance of Payments. So, Statement 2 is not correct.
  • The head of invisibles in the Balance of Payments records the receipts and payments with respect to the following:
    • Import and export of Services
    • Income/ Remittances
    • Transfers These neither create an asset nor a liability. So, the head of invisibles falls under the current account and not the capital account. So, Statement 3 is not correct.
  • Companies of a country can go abroad to sell their shares in the foreign capital market. When a foreign investor buys shares of domestic companies abroad (in the capital market), he is issued a receipt by a Custodian Bank. This receipt represents a certain number of underlying shares of domestic companies; hence, they are called depository receipts. The depository receipts raised by Indian companies in the American market are called American Depository Receipts (ADRs). Those raised in some other countries are called Global Depository Receipts (GDRs). They form a part of the Capital account in the context of the Balance of Payments. So, Statement 4 is correct.
Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 22

With reference to Digital Security Infrastructure in India, consider the following statements :

1. The Information Technology Act 2000 provides legal sanctity to digital signatures in India.

2. Certifying Authorities licensed by the Controller of Certifying Authorities (CCA) issue Digital Signature Certificates.

3. The electronic documents that have been digitally signed are not treated at par with paper documents.

4. The Data Security Council of India (DSCI), set up by the Ministry of electronics, is committed to making cyberspace safe and secure.

Which of the statements given above are correct?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 22
  • Section 3(1) of the Information Technology Act of 2000 gives legal sanctity to the usage of digital signatures in the country. A person can, if he/she wishes, use digital signatures to authenticate an electronic record, and such authentication is now recognizable under the law. Section 2(p) of the Act defines ‘digital signature’ as ‘authentication of any electronic record by a subscriber by means of an electronic method or procedure in accordance with the provisions of section 3’. Chapter II of the Act has a single section which is section 3, providing for the authentication of electronic records. Sub-section (1) of section 3 states that ‘any subscriber may authenticate an electronic record by affixing his digital signature.’ This forms the basis for the use of digital signatures. So, Statement 1 is correct.
  • The IT Act of 2000 creates a hierarchy in which at the top is the Controller of Certifying Authorities, who has the power to appoint Certifying Authorities and grant them the license to issue Digital Signature Certificates. In turn, the Certifying Authorities can issue such Certificates to the subscribers. So, Statement 2 is correct.
  • The IT Act of 2000 adopts the functional equivalent approach. When adopting this approach in the UNCITARL Model Law, attention was given to the existing hierarchy of form requirements, which provides a distinct level of reliability, traceability and inalterability with respect to paper-based documents. This approach singles out the basic functions of paper-based form requirements with a view to providing criteria which, once they are met by electronic documents, enable such e-documents to enjoy the same level of legal recognition as corresponding paper documents performing the same function enjoy. As per Section 18 of The Information Technology Act, 2000 provides the required legal sanctity to the digital signatures based on asymmetric cryptosystems. The digital signatures are now accepted at par with handwritten signatures and the electronic documents that have been digitally signed are treated at par with paper documents. So, Statement 3 is not correct.
  • The Data Security Council of India (DSCI) is a not-for-profit industry body on data protection in India, set up by NASSCOM, a non-governmental industry organization. DSCI is committed to making cyberspace safe, secure and trusted by establishing best practices, standards and initiatives in cyber security and privacy. To further its objectives, DSCI engages with governments and their agencies, regulators, industry sectors, industry associations and think tanks for policy advocacy, thought leadership, capacity building and outreach activities. So, Statement 4 is not correct.

1. A Trademark is a unique sign used by businesses to distinguish themselves.

2. It provides the owner exclusive rights and is protected by Intellectual Property rights.

3. Once registered, it has perpetual validity.

4. The Ministry of Corporate Affairs manages trademarks.

Which of the above statements are correct ?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 23
  • The term trademark refers to a recognizable insignia, phrase, word, or symbol that denotes a specific product and legally differentiates it from all other products of its kind. A trademark exclusively identifies a product as belonging to a specific company and recognizes the company's ownership of the brand. Trademarks are generally considered a form of intellectual property and may or may not be registered. Intellectual property rights protect trademarks. So, Statements 1 and 2 are correct.
  • The Trademark Act 1999 governs the trademark regime and registration. The Act guarantees protection for a trademark registered with the Controller General of Patents, Designs, and Trademarks, also known as the trademark registry. A trademark is valid for 10 years and can be renewed by the owner indefinitely every 10 years. So, Statement (3) is not correct.
  • Trademark rights are private rights, and protection is enforced through court orders. The Controller General of Patents, Designs and Trade Marks heads the TRADE MARKS Registry offices and functions as the Registrar of TRADE MARKS. From time to time, he assigns functions of the Registrar to other officers appointed by the Central Government, and such officers also function as Registrar in respect of matters assigned to them. The Office of the Controller General of Patents, Designs & Trade Marks (CGPDTM) is located in Mumbai. It functions under the Department of Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce & Industry. The Controller General supervises the working of the Patents Act of 1970, the Designs Act of 2000 and the Trade Marks Act of 1999 and also renders advice to the Government on matters relating to these subjects. The Head Office of the ‘Patent office’ is in Kolkata, the ‘Trade Mark Registry’ is in Mumbai and the ‘GI Registry’ is in Chennai. The Offices of ‘The Patent Information System’ (PIS) and ‘National Institute of Intellectual Property Management’ (NIIPM) are at Nagpur. So, Statement (4) is not correct.

  • It is caused by the Lassa virus, a member of the arenavirus family of viruses.

  • Unlike the Ebola virus, Lassa fever is not as contagious from person to person, nor as deadly. Hence, statement 2 is not correct.

  • Lassa virus is typically transmitted by the urine or feces of Mastomys rats to humans. Hence, statement 3 is correct.

  • Health workers may be infected by direct contact with blood, body fluids, urine, or stool of a patient with Lassa fever.

  • Lassa fever occurs primarily in West Africa in areas where these rodents live. Blueprint Priority Diseases of WHO: Worldwide, the number of potential pathogens is very large, while the resources for disease research and development (R&D) is limited. To ensure efforts under WHO‘s R&D Blueprint are focused and productive, a list of diseases and pathogens are prioritized for R&D in public health emergency contexts. A WHO tool distinguishes which diseases pose the greatest public health risk due to their epidemic potential and/or whether there is no or insufficient counter-measures.

    At present, the priority diseases are:

    • COVID-19

    • Crimean-Congo hemorrhagic fever

    • Ebola virus disease and Marburg virus disease

    • Lassa fever

    • Middle East respiratory syndrome coronavirus (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS)

    • Nipah and henipaviral diseases

    • Rift Valley fever

    • Zika

    • Disease X‖: Disease X represents the knowledge that a serious international epidemic could be caused by a pathogen currently unknown to cause human disease. The R&D Blueprint explicitly seeks to enable early cross-cutting R&D preparedness that is also relevant for an unknown ―Disease X‖.

Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 25

Consider the following pairs:

Which of the pairs given above is/are correctly matched?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 25
The p-Block Elements comprise those belonging to Group 13 to 18 and these together with the s-Block Elements are called the Representative Elements or Main Group Elements.

At the end of each period in a periodic table is a noble gas element with a closed valence shell. All the orbitals in the valence shell of the noble gases are completely filled by electrons and it is very difficult to alter this stable arrangement by the addition or removal of electrons. The noble gases thus exhibit very low chemical reactivity.

Noble gases have uses that are derived from their other chemical properties. The very low boiling points and melting points of the noble gases make them useful in the study of matter at extremely low temperatures. Therefore often used for specific industrial processes.

  • The low solubility of helium in fluids leads to its admixture with oxygen for breathing by deep-sea divers: because helium does not dissolve in the blood, it does not form bubbles upon decompression (as nitrogen does, leading to the condition known as decompression sickness, or the bends).

  • Xenon has been used as an anesthetic; although it is costly, it is non-flammable and readily eliminated from the body.

  • Radon is highly radioactive; its only uses have been those that exploit this property (e.g., radiation therapy). (Oganesson is also radioactive, but, since only a few atoms of this element have thus far been observed, its physical and chemical properties cannot be documented.).

  • Krypton is used in fluorescent bulbs, flashbulbs, and lasers. Lamps filled with krypton are used at some airports as approach lights since their light can penetrate dense fog unusually well.

  • Neon is also used as fog lights. Hence option (d) is the correct answer.

Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 26

Which of the following statements is/are correct?

  1. Chloroplasts are green-colored plastids, which comprise pigments called chlorophyll.

  2. Chloroplasts are found in all green plants and algae.

Which of the statements given above is/are correct?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 26
  • Chloroplasts: They are green-colored plastids, which comprise green-colored pigments within the plant cell and are called chlorophyll. Hence, statement 1 is correct.

  • Chloroplast is an organelle that contains the photosynthetic pigment chlorophyll that captures sunlight and converts it into useful energy, thereby, releasing oxygen from water.

  • Chloroplasts are found in all green plants and algae. They are the food producers of plants. These are found in the guard cells located in the leaves of the plants. They contain a high concentration of chlorophyll that traps sunlight. This cell organelle is not present in animal cells. Hence, statement 2 is correct.

  • Chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They also produce amino acids and lipids required for the production of chloroplast membrane.

  • Functions of Chloroplast: Following are the important chloroplast function:

    • The most important function of the chloroplast is to synthesize food by the process of photosynthesis.

    • Absorbs light energy and converts it into chemical energy.

    • Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and used for the synthesis of food in all green plants.

    • Produces NADPH and molecular oxygen (O2) by photolysis of water.

    • Produces ATP – Adenosine triphosphate by the process of photosynthesis.

    • The carbon dioxide (CO2) obtained from the air is used to generate carbon and sugar during the Calvin Cycle or dark reaction of photosynthesis.

    • Where does the photosynthesis process occur in the plant cell?

    • In all green plants, photosynthesis takes place within the thylakoid membrane of the Chloroplast.

Select the correct answer using the code given below:

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 27
Coronal Holes are areas on the sun's surface where fast solar wind erupts into space. Hence, statement 1 is correct.

In these regions, the magnetic field is open to interplanetary space, sending solar material

out in a high-speed stream of solar wind i.e., geomagnetic storm.

Coronal holes can last between a few weeks to months thus not a permanent formation. Hence, statement 2 is not correct.

The holes are not a unique phenomenon, appearing throughout the sun’s approximately 11-year solar cycle.

Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 28

Bowman‟s capsule and glomerulus are associated with which organ of the human

Body?

Detailed Solution for Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 28
A nephron is the basic structural and functional unit of the kidney. They are the microscopic structure composed of a renal corpuscle and a renal tubule.

Structure of Nephron

  • The mammalian nephron is a long tube-like structure, its length varying from 35–55 mm long. At one end, the tube is closed, folded and expanded, into a double-walled, cuplike structure called the Bowman‘s capsule or renal corpuscular capsule, which encloses a cluster of microscopic blood vessels called the glomerulus. This capsule and glomerulus together constitute the renal corpuscle.

Functions of Nephron

  • The primary function of the nephron is removing all waste products including the solid wastes, and other excess water from the blood, converting blood into urine, reabsorption, secretion, and excretion of numerous substances.

  • As the blood passes through the glomerulus with high pressure, the small molecules are moved into the glomerular capsules and travel through a winding series of tubules.

  • The cell present in each tube absorbs different molecules excluding the glucose, water, and other beneficial molecules which are called ass ultrafiltrate. As the ultrafiltrate molecules travel down the tubules they become more and more hypertonic, which results in more amount of water to be extracted from the ultrafiltrate before it exits the nephrons.

  • The blood surrounding the nephron travels back into the body through the renal blood vessels, which are free of toxins and other excess substances. The obtained ultrafiltrate is urine, which travels down via the collecting duct to the bladder, where it will be stored and released through the urethra.

Kerala PSC KAS Prelims Paper 2 Mock Test - 10 - Question 29

  • A clone is a living organism (such as a plant or animal), which shares the same genetic information as another organism. However, their characteristics can be affected by random mutations which occur in their DNA during development in the womb or by the environment that they grow up in, so, although clones have the same DNA, they may not look the same or behave in the same way.

  • While some clones can be found in nature, it is also possible for scientists to create a clone or identical copy of an organism. It is important to understand that a cloned animal is not the same as a genetically modified animal. Hence, statement 1 is correct.

  • A cloned animal shares the same DNA as another animal, while a genetically modified animal has had a change made to its DNA, but does not share its DNA with any other animals. Hence, statement 2 is correct.

  • Scientists can also use bacteria or viruses to replicate or clone individual DNA sequences that they are interested in. This is known as molecular or DNA cloning.
