Which of the statements given above is/are correct?
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
Answer: (a) 1 only
Explanation:
In NEWS: Explained: How surgeons gave a pig heart — and hope of life — to a human
● Recently the doctors in the USA transplanted a genetically altered pig heart into a patient which is referred to as xenotransplantation (from animals to humans).
● The donor pig underwent 10 genetic modifications, by which the genes responsible for the rapid rejection of foreign organs by the human body were inactivated or knocked out.
● Four pig genes were removed, and six human genes were added.
● GalSafe pigs, or pigs that had undergone editing to knock out a gene that codes for Alpha-gal (a sugar molecule) were used. Alpha-gal can elicit a devastating immune response in humans.
● GalSafe pigs have been well studied, and are approved by the US Food and Drug Administration (FDA) for use in pharmacology.
Cross-species transplant
● Xenotransplantation, or transplanting organs across different species, was first tried in humans in the 1980s.
● The experiment was abandoned after the famous case of the American Baby Fae who was born with a congenital heart defect and received a baboon heart in 1984.
● Xenotransplantation is any procedure that involves the transplantation of either live cells, tissues, or organs from a nonhuman animal source, or human body fluids, cells, tissues or organs into a human recipient. Hence, statement (1) is correct and statement (2) is incorrect.
● It also includes any procedure in which human body fluids, cell tissues, or organs have ex vivo contact with live human animal cells, tissues, or organs. More generally, xenotransplantation defines any cross-species transplantation (e.g., mouse to rat, pig to primate, and sheep to human).
● In biomedical research, a recent approach to xenotransplantation targets pigs as source animals with the goal of transplanting pig solid organs, such as kidneys, hearts, and livers, into humans.
● Pigs are a promising donor species for xenotransplantation. However, when pig organs are transplanted into primates, hyperacute rejection, acute humoral xenograft rejection, acute cellular xenograft rejection, and chronic xenograft rejection develop.

4. Consider the following statements:
1) Cryptocurrency transactions are taxable under income tax act, 1960.
2) In India, trading in cryptocurrency may be classified as transfer of a ‘capital asset’.
Which of the statements given above is/are correct?
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
Answer: (c) Both 1 and 2
Explanation:
In NEWS: Taxing cryptocurrency transactions
● Notwithstanding the eventual introduction of the Cryptocurrency and Regulation of Official Digital Currency Bill in Parliament, cryptocurrencies continue to proliferate.
● In fact, a liberal estimate suggests that as many as 10 crore Indians may already have investments exceeding a total of $10 million in them.
● Transparency in transaction: cloak of invisibility make tax evaders to park their black money abroad and fund criminal activities, terrorism, etc. so, transparency brought visibility of the transaction.
● Although the Income Tax Act, 1961 (“IT Act”) does not specifically mention cryptocurrencies, it does cast a wide enough net to bring crypto transactions under its ambit.
● Crypto currency transactions are taxable under income tax act, 1960. Hence, statement (1) is correct.
● Trading in cryptocurrency may be classified as transfer of a ‘capital asset’, taxable under the head ‘capital gains’. However, if such cryptocurrencies are held as stock-in trade and the taxpayer is trading in them frequently, the same will attract tax under the head ‘business income’. Hence, statement (2) is correct.
● Even if one argues that crypto transactions do not fall under the above heads, Section 56 of the IT Act shall come into play, making them taxable under the head ‘Other sources of income’.
● However, this in itself is not sufficient in order to put in place a simple yet effective taxation regime for cryptocurrencies. Since cryptocurrencies are unlike any other asset class, stored and traded virtually, there are varied challenges which need to be addressed in order to streamline the process of taxing crypto transactions.

6. Katrol Hill Fault is associated with which of the following regions in India?
a) Kachchh region
b) Chambal region
c) Siliguri region
d) None of the above
Answer: (a) Kachchh region
Explanation:
In NEWS: Spectacular landscape changes detected in Gujarat’s Kachchh region due to major earthquakes in recent geological past
● Major earthquake events in the last 30,000 years resulted in spectacular changes in landscape of the Katrol Hill Fault in the Kachchh region in Gujarat, a study conducted on sediment samples revealed.
● These surprising geological facts about the seismic history of the fault in the recent geological past necessitate a revised seismic hazard assessment and mitigation strategies in Kachchh Basin, owing to its close proximity to industrial corridors and major settlements, including Bhuj city.
Katrol Hill Fault (KHF):
● It is situated in the Kachchh region in Gujarat. Hence option (a) is correct.
● A study of sediment showed that Seismicity in the Kutch region is highly complex as it is characterized by multiple seismic sources in the form of several East-West trending fault lines, which release continuously accumulating tectonic stresses at intervals producing earthquakes.
● The study was carried out by field mapping and using sophisticated field instruments like Ground Penetrating Radar and laboratory equipment like Scanning Electron Microscope for analyzing sediment samples.
● The samples showed features indicative of surface faulting.
● The Katrol Hill Fault (KHF) has produced high magnitude seismic events during the past ~30,000 years and is, therefore, a credible seismic source capable of generating surface rupture hazards in the Kachchh Basin.
● Further, field-based geomorphological studies revealed that the events resulted in spectacular changes in the landscape, as evidenced by the disruption and reorganization of the channel of the Gunawari River in the fault zone.
● It is interesting that these events produced surface rupture, whereas the 2001 Bhuj earthquake (Mw 7.7) did not rupture the surface.
