its price falls

Which of the above statements are correct?

(a) 1 and 4 only

(b) 2, 3 and 4

(d) 1, 2 and 3

Ans: (a)

Explanation:

Law of Demand states that other things being equal, there is a negative relation between demand for a commodity and its price. In other words, when price of the commodity increases, demand for it falls and when price of the commodity decreases, demand for it rises, other factors remaining the same. Hence, statement 4 is correct.
The demand for a good usually increases if the price of its substitutes increases. Hence, statement 1 is correct.
Goods which are consumed together are called complementary goods. In general, the demand for a good move in the opposite direction of the price of its complementary goods. Hence, statement 2 is not correct.
There are some goods the demands for which move in the opposite direction of the income of the consumer. Such goods are called inferior goods. As the income of the consumer increases, the demand for an inferior good falls, and as the income decreases, the demand for an inferior good rises. Examples of inferior goods include food items like coarse cereals. Hence, statement 3 is not correct.
Therefore, option (a) is the correct answer.

Urban Co-operative Banks (UCB) are regulated and supervised by State Registrars of Co-operative Societies (RCS) in case of single-state co-operative banks and Central Registrar of Co-operative Societies (CRCS) in case of multi-state co-operative banks and by the RBI. Hence, statement 1 is not correct.
The banking related functions such as issue of license to start new banks/branches, matters relating to interest rates, loan policies, investments and prudential exposure norms are regulated and supervised by the Reserve Bank under the provisions of the Banking Regulation Act, 1949 after an amendment in 1966. Hence, statement 3 is correct.
The UCBs could raise share capital by issue of equity to persons within their area of operation enrolled as members and also through additional equity shares to the existing members. Hence, statement 2 is correct.
Therefore, option (b) is the correct answer.

36. Indian Government Bond Yields are influenced by which of the following?

Actions of the United States Federal Reserve

The actions of the RBI plays a crucial role in determining the yield of government bonds. The sovereign yield curve has a special significance for monetary policy in influencing a wide array of interest rates in the economy. Hence, 2 is correct.
Inflation and short-term interest rates also influence the yield of government bonds. Hence, 3 is correct.
Therefore, option (d) is the correct answer.

37. Consider the following:

Foreign currency convertible bonds
Foreign institutional investment with certain conditions
Global depository receipts
Non-resident external deposits

Which of the above can be included in Foreign Direct Investments?

(a) 1, 2 and 3

(b) 3 only

(d) 1 and 4

Ans: (a)

Explanation:

Foreign Currency Convertible Bonds (FCCBs) are foreign currency convertible Bonds invested in Indian company. Since these bonds are convertible into equity shares over a period of time as provided in the instrument, therefore they are covered under FDI policy and inward remittances received by the Indian company vide issuance of FCCBs are treated as FDI and counted towards FDI. Hence, 1 is correct.
Foreign Institutional Investor (FII) is not FDI in general as FIIs can invest up to a maximum of 10 percent of the total paid-up capital, however, if FII invest in convertible debenture then it is counted as FDI subject to certain limitations. Hence, 2 is correct.
Indian companies can raise foreign currency resources abroad through the issue of American Depository Receipt (ADR)/Global Depository Receipts (GDRs) in accordance with the Scheme for issue of Foreign Currency Convertible Bonds and Ordinary Shares (through Depository Receipt Mechanism) Scheme, 1993 and guidelines issued by the Government of India thereunder from time to time. Therefore, bonds cannot be FDI but Convertible Bond/Debenture could be converted to Equity and included under FDI. Hence, 3 is correct.
Non-resident external deposits are not treated as FDI as banks can route these deposits for loans. NRIs can invest in shares on recognized stock exchanges under portfolio investment route. The investment can be repatriable or non-repatriable, but the maximum limit of investment is 10% of paid-up capital of the relevant company. Hence, 4 is not correct.
Therefore, option (a) is the correct answer.

38. Consider the following statements:

improves the competitiveness of the domestic exports in the foreign markets
increases the foreign value of domestic currency
improves the trade balance

Which of the above statements is/are correct?

(a) 1 only

(b) 1 and 2

(d) 2 and 3

Ans: (a)

Explanation:

Currency devaluation is the deliberate reduction in the value of a country’s currency against another currency. A country pursues a policy of devaluation to boost its exports as its products and services become cheaper to buy. In other words, the competitiveness of domestic exports improves in the foreign markets. Devaluation will not increase the foreign value of domestic currency. Hence, 1 is correct and 2 is not correct.
Devaluation of currency is often done by the monetary authorities when they need to improve the country’s trade balance. However, it is not necessary that it will improve the trade balance as import can be expensive. Hence, 3 is not correct.
Therefore, option (a) is the correct answer.

40. Which one of the following is likely to be the most inflationary in its effect?

(a) Repayment of public debt

(b) Borrowing from the public to finance a budget deficit

(d) Creation of new money to finance a budget deficit

Ans: (d)

Explanation:

Printing new currency notes increases the flow of money in the economy. As the flow of money raises aggregate expenditure, the aggregate demand also increases and the danger of inflation becomes large.
With the creation of new money, the amount of goods does not change. Therefore, if the money supply is increased, but the goods remain the same, everything will become more expensive.
If the government keeps printing more, the economy will start experiencing hyperinflation. Moreover, the currency will also devalue against other currencies.
So, among all the deficit financing methods creating more money will have the most inflationary effect.
Therefore, option (d) is the correct answer.

41. Which one of the following is used in preparing a natural mosquito repellent?

Explanation:

Symbiosis is a close ecological relationship between the individuals of two (or more) different species.

The symbiotic association between the invertebrate phylum Cnidaria (Coelenterate) and the unicellular dinoflagellate algae, called zooxanthellae, is very common and symbolises mutualistic interaction. Hence, 1 is correct.
Mycorrhizae are symbiotic relationships that are formed between fungi and plants. The fungi colonize the root system of a host plant, providing increased water and nutrient absorption capabilities while the plant provides the fungus with carbohydrates formed from photosynthesis. Hence, 2 is correct.
Termites have a mutualistic relationship with protozoa that live in the insect’s gut. The termite benefits from the ability of bacterial symbionts within the protozoa to digest cellulose. The termite itself cannot do this, and without the protozoa, it would not be able to obtain energy from its food (cellulose from the wood it chews and eats). Hence, 3 is correct.
Therefore, option (d) is the correct answer.

A foreigner once granted citizenship cannot be deprived of it under any circumstances.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(d) 2 and 3

Ans: (a)

Explanation:

The term ‘Domicile’ means a permanent home. A person cannot have more than one domicile. According to the Article 9 of Indian Constitution, if any person voluntarily acquired the citizenship of a foreign State will no longer be a citizen of India. So In India, there is single citizenship and one domicile. Hence, statement 1 is correct.
Article 58 signifies nowhere that citizenship should be by birth or naturalization. Similarly, to become a Prime Minister (Head of Government) one has to be: a citizen of India (irrespective of by birth or naturalization) and a member of either Rajya Sabha or Lok Sabha. Hence, statement 2 is not correct.
The Provisions related to the termination of Citizenship are also mentioned in the Indian Citizenship Act, 1955. Under Section (10) of this Act, the Central Government of India may terminate the citizenship of an Indian citizen if;
The citizen has disrespected the Constitution.
Has obtained citizenship by fraud.
The citizen has unlawfully traded or communicated with the enemy during a war.
Within 5 years of registration or naturalisation, a citizen has been sentenced to 2 years of imprisonment in any country.
The citizen has been living outside India for 7 years continuously except for purposes other than educational or in service of a government or international organization of which India is a member or he has not registered annually at an Indian consulate expressing his intention to retain his citizenship. Hence, statement 3 is not correct.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(d) Neither 1 nor 2

Ans: (c)

Explanation:

The technological development allows nearly complete replacement of the cytoplasm of egg/embryo, eliminating the transmission of undesired defective mitochondria for patients with inherited mitochondrial diseases, which is called mitochondrial replacement therapy (MRT). These processes use assisted reproductive technology, including in vitro fertilization. The father’s sperm can fertilize the patient egg before the maternal genetic material is removed or after the maternal genetic material has been transferred to the donor egg. Hence, statement 1 is correct.
Mitochondrial diseases are chronic (long-term), genetic, often inherited disorders that occur when mitochondria fail to produce enough energy for the body to function properly. As the mitochondrial genome is inherited exclusively from the mother, the child inherits mitochondrial diseases entirely from mother and not from father. Hence, statement 2 is correct.
Therefore, option (c) is the correct answer.

Select the correct answer using the code given below.

(a) 1 and 2 only

(b) 2 and 3 only

(d) 1, 2 and 3

Ans: (d)

Explanation:

The Charles law states that pressure (P), volume (V) and temperature (T) is equal to a constant K i.e. PVT = k.
From the above-given equation, we can infer that temperature is dependent on pressure and volume. Pressure in the cooker depends on the area of the hole in the lid, the bigger the hole in the lid, the lesser will be the pressure inside the cooker and hence temperature will be affected. Hence, 1 is correct.
The more is the temperature of the flame the more will be the temperature inside the cooker. Hence, 2 is correct.
The weight of the lid has a direct connection in relation to maintaining enough pressure in the lid, heat release and heat-storing inside the cooker and hence can be linked with the temperature inside the cooker. Hence, 3 is correct.
Therefore, option (d) is the correct answer.

(a) 1 only

(b) 2 only

(d) Neither 1 nor 2

Ans: (b)

Explanation:

Adenovirus is a type of virus that has no envelope whereas retroviruses are characterized as enveloped viruses. Adenoviruses have double-stranded linear DNA and are associated with two major core proteins. A retrovirus is a virus that uses RNA as its genetic material. When a retrovirus infects a cell, it makes a DNA copy of its genome that is inserted into the DNA of the host cell. Hence, statement 1 is not correct.
Adenoviruses are common viruses that cause a range of illnesses. They can cause cold-like symptoms, fever, sore throat, bronchitis, pneumonia, diarrhoea, and pink eye (conjunctivitis). Whereas, retroviruses can cause several human diseases such as some forms of cancer and AIDS. Hence, statement 2 is correct.
Therefore, option (b) is the correct answer.

81. How is permaculture farming different from conventional chemical farming?

Permaculture farming discourages monocultural practices but in conventional chemical farming, monoculture practices are predominant.

Conventional chemical farming is easily possible in semi-arid regions but permaculture farming is not so easily possible in such regions.
Practice of mulching is very important in permaculture farming but not necessarily so in conventional chemical farming.

Select the correct answer using the code given below.

(a) 1 and 3

(b) 1, 2 and 4

(d) 2 and 3

Ans: (b)

Explanation:

Permaculture is a totally integrated design system that is modelled on nature. Permaculture farming promotes multi cropping and integrated farming systems, whereas chemical farming is more suitable for monoculture cropping due to use of crop specific inputs like irrigation, chemical fertiliser and harvesting methods. Hence, 1 is correct.
Chemical farming makes the soil less fertile over time due to use of chemical fertilizers, which can lead to serious problems like soil salinisation. But such problems do not occur in permaculture farming as it relies on organic fertilizers. Hence, 2 is correct.
The concept of permaculture involves well-designed systems that do not produce waste and tries to copy well-designed systems. Permaculture tries to take into account local conditions like arid climate, which helps in developing a suitable system to ensure sustainable production. In case of chemical farming, intense use of chemical fertilizers and irrigation make the soil less fertile over time, thus restricting its practice in semi-arid regions. Thus, conventional chemical farming is not suitable for semi-arid regions. Hence, 3 is not correct.
Mulching is a long-established horticultural practice that involves spreading a layer of material on the ground around plants to protect their roots from heat, cold, or drought or to keep the fruit clean.The material used for covering is called ‘mulch’. Mulching is usually practiced while cultivating commercially important crops, fruit trees, vegetables, flowers, nursery saplings, etc. Mulching is an important component of permaculture farming for promoting maximum efficiency. Whereas, conventional chemical farming does not consider it as essential. Hence, 4 is correct.
Therefore, option (b) is the correct answer.

Sodium lamps produce light in 360 degrees but it is not so in the case of LED lamps.
As street lights, sodium lamps have a longer lifespan than LED lamps.
The spectrum of visible light from sodium lamps is almost monochromatic while LED lamps offer significant colour advantages in street lighting.

Select the correct answer using the code given below.

(a) 3 only

(b) 2 only

(d) 1, 2 and 3

Ans: (c)

Explanation:

LEDs emit light for 180 degrees. This is typically an advantage because the light is usually desired over a target area (rather than all 360 degrees around the bulb). Whereas Sodium lamps emit light omnidirectionally. This means they emit light for 360 degrees, requiring fixture housings or reflectors to direct a large portion of the emissions to the desired target area. Hence, 1 is correct.
LEDs have an extremely long lifespan relative to every other lighting technology. New LEDs can last 50,000 to 100,000 hours or more. Hence, 2 is not correct.
Sodium lamps have the worst colour rendering of any bulb. They produce a dark yellow glow which is generally a very low-quality light. LEDs are available in a wide range of colour temperatures that generally span from 2200K-6000K (ranging from “warm” yellow to light or “cool” blue). Hence, 3 is correct.
Therefore, option (c) is the correct answer.

93. The term ‘ACE2’ is talked about in the context of

(a) genes introduced in the genetically modified plants

(b) development of India’s own satellite navigation system

In the 1991 Lok Sabha Election, Shri Devi Lal contested from three Lok Sabha constituencies.
As per the existing rules, if a candidate contests in one Lok Sabha election from many constituencies, his/her party should bear the cost of bye-elections to the constituencies vacated by him/her winning in all the constituencies.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(d) 2 and 3

Ans: (b)

Explanation:

In 1996, the Representation of the People Act, 1951 was amended to restrict from ‘three’ to ‘two’ the number of seats one candidate could contest in Lok Sabha and Assembly elections. Hence, statement 1 is not correct.
In 1991, Shri Devi Lal contested three Lok Sabha seats, Sikar, Rohtak and Ferozepur seats. Hence, statement 2 is correct.
Whenever a candidate contests from more than one seat and wins more than one, the candidate has to retain only one, forcing by polls in the rest. It results in an unavoidable financial burden on the public exchequer, government manpower and other resources for holding by-election against the resultant vacancy. Hence, statement 3 is not correct.
Therefore, option (b) is the correct answer.
