Daily Current Affairs MCQ- May 21, 2024 - Question 1

Consider the following statements with reference to the Port of Call:

1. It is an intermediate stop for a ship on its scheduled journey for cargo operation. 

2. Aden and Honolulu ports are the examples of Ports of Call.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ- May 21, 2024 - Question 1

Recently, Spain has refused permission for an Israel-bound ship carrying arms to call at the southeastern port of Cartagena.

  • It is an intermediate stop for a ship on its scheduled journey for cargo operation or transporting supplies or fuel. It is a port where a ship stops except its home port.
  • These are the ports which originally developed as calling points on main sea routes where ships used to anchor for refuelling, watering and taking food items. Later on, they developed into commercial ports.
  • Examples: Aden, Honolulu and Singapore are good examples.
  • It is also called port of refuge, port of call is usually not a part of a ship’s itinerary. The vessel may “call” the said intermediate port and need a stopover due to various reasons, like:
  • Cargo operations (cleaning, repairs, or maintenance)
  • Stock up supplies (fuel, food, etc.)
  • Load and unload cargo
  • Unforeseen emergencies
  • Depending on the reason for stopping, port of call can also be divided into subcategories, like:
  • Dry harbor (for vessel maintenance), Cargo harbor (for cargo dispersal) and Fish harbor (for dropping fishes), etc.

Hence both statements are correct.

Daily Current Affairs MCQ- May 21, 2024 - Question 4

Consider the following statements with reference to the Psychedelic drugs:

1. They induce states of altered perception and behavior.

2. Classical psychedelics trigger hallucinations by activating a receptor called serotonin 5-HT in human body.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ- May 21, 2024 - Question 4

Driven by surge in global trials and low success rate of current medications in treating mental health problems, researchers call for home-grown clinical trials of psychedelic drugs.

  • These are drugs that induce states of altered perception, behaviour, consciousness and thought, often with increased awareness of the senses.
  • The term ‘psychedelic’ comes from two Greek words denoting mind or soul and manifesting. It is a subset of psychotropic substances that can alter a person’s thoughts and perceptions, and elicit intense hallucinations.
  • These are categorised into two broad categories
  • Classical psychedelics: These are thought to trigger hallucinations by activating a receptor called serotonin 5-HT, which is widely present in the human body, from the gastrointestinal tract to platelets to the nervous system. Examples: LSD, psilocybin and DMT
  • Nonclassical psychedelics: These psychedelics bind to varied receptors. Examples: ketamine and MDMA
  • Globally, about five psychedelics are the subject of clinical research for use in treating mental health problems: psilocybin; lysergic acid diethylamide (LSD); 3,4-methylenedioxy-N-methamphetamine (MDMA); ketamine and N, N-dimethyltryptamine (DMT).
  • Most psychedelics work by increasing the availability of serotonin—a mood stabilising hormone—in the brain by binding to serotonin receptors (a molecule on the cell surface that binds to a specific chemical, causing a specific effect).
  • The United Nations’ Convention on Psychotropic Substances, 1971, lists about 200 psychotropic substances under four schedules, with schedule I substances having the most potential for abuse. The Convention does not specify which substances, or how many, are psychedelics. 

Hence both statements are correct.

Daily Current Affairs MCQ- May 21, 2024 - Question 5

Which one of the following statements best describes, ‘Pig Butchering Scam’, recently seen the news?

Detailed Solution for Daily Current Affairs MCQ- May 21, 2024 - Question 5

An online financial fraud called Pig Butchering Scams are increasing across the globe, including in India.

  • It is also known as a “sha zhu pan” scam, is a type of online investment fraud that involves scammers creating fake online personas to lure victims into fraudulent investment schemes.
  • The term “pig butchering” comes from the scammers’ practice of “fattening up” their victims by building trust over time before “slaughtering” them and stealing their money.
  • How it is carried out?
  • It all begins with the “host" contacting people online through social media, dating apps, or deceptive messages.
  • Once they’ve found a target, known as the “pig," the host establishes a false sense of friendship and encourages them to explore cryptocurrency trading.
  • Using a fraudulent trading app, the host deceives the victim into believing they’re making profits from fabricated trades.
  • Gradually, as the victim’s trust grows, the host persuades them to invest more money, a tactic referred to as “fattening the pig" before the scam is revealed.
  • When victims attempt to withdraw their funds, the fake platform either makes excuses or imposes substantial fees, ultimately exposing the scam. Retrieving lost funds is exceedingly difficult due to the nature of blockchain transactions.

Hence option (d) is the correct answer.

Daily Current Affairs MCQ- May 21, 2024 - Question 6

The Scarborough Shoal is located in which one of the following water bodies?

Detailed Solution for Daily Current Affairs MCQ- May 21, 2024 - Question 6

The Philippines recently challenged China to open Scarborough Shoal to international scrutiny after it accused Beijing of destroying the shoal's marine environment.

About Scarborough Shoal:

  • The Scarborough Shoal (also known in English as the Scarborough Reef) is a series of small rocks and islands which are formed into a triangle shape in the South China Sea, located some 220 kilometers from the Philippines.
  • The largest island features a lagoon and is around sixty square miles in area, while many of the rocks are so small they protrude only a metre or so from the sea at low tide and arecompletely submergedwhen the tide is high.
  • The deep waters around the shoal make it a productive fishing area, rich in marine life, and the lagoon also contains many commercially valuable shellfish and sea cucumbers.
  • The shoal is the source of an ongoing and, so far, unresolved dispute between the People’s Republic of Chinaand the Philippines, with both countries claiming that the shoal lies within their territory and saying they have exclusive rights to access its waters.
  • There are no structures built on Scarborough Shoal, but the feature is effectively controlled by China, which has maintained a constant coast guard presence at the feature since 2012.
  • China, which now refers to the shoal as Huangyan Island, makes a historical claim to the area, stating that they can trace their ownership of the area back to the Yuan Dynasty of the 1200s.
  • The Philippines claim the area on the basis of geography, as it is much closer to the Philippines’ main island of Luzon, which contains the capital, Manila, but lies over 500 miles from China.

Hence option c is the correct answer.

Daily Current Affairs MCQ- May 21, 2024 - Question 8

R21/Matrix-M vaccine, recently seen in the news, is developed for the prevention of which one of the following diseases?

Detailed Solution for Daily Current Affairs MCQ- May 21, 2024 - Question 8

Vaccines manufacturer Serum Institute of India (SII) recently said it has started exports of 'R21/Matrix-M' malaria vaccine to Africa as part of the global fight against the disease.

About R21/Matrix-M Vaccine:

  • It is a new vaccine approved for the prevention of malaria in children.
  • It is the second malaria vaccinerecommended by the World Health Organization (WHO), following the RTS,S/AS01 vaccine, which received a WHO recommendation in 2021. 
  • The vaccine was developed by the Jenner Institute at Oxford University and the Serum Institute of India with support from the European and Developing Countries Clinical Trials Partnership ('EDCTP'), the Wellcome Trust, and the European Investment Bank ('EIB').
  • This low-cost, high-efficacy vaccine is already licensed by several African countries.
  • How does the R21/Matrix-M vaccine Works?
  • Vaccines work by putting the antigen, which is the piece of the virus or bacteria that our system recognises and responds to, in front of our immune cells. 
  • The R21/Matrix-M vaccine targets the plasmodium 'sporozoite', which is the first form of the malaria parasite entering the human body.
  • Only a few (10–100) sporozoites are injectedby infected mosquitoesbefore the parasite multiplies, making them the ideal targetfor a vaccine. 
  • R21 is a subunit vaccine that delivers parts of a proteinsecretedby the sporozoite that are bundled upwith a part of the hepatitis B virus that is known to trigger a strong immune response.
  • The vaccine also contains Matrix-M, an "adjuvant" which boosts the immune system’s response to make it more powerful and long-lasting.

Hence option d is the correct answer.

Daily Current Affairs MCQ- May 21, 2024 - Question 9

Consider the following statements with reference to the Genetic Drift:

1. It takes place when the occurrence of variant forms of a gene increases or decreases by chance over time in a population.

2. Large populations are more susceptible to genetic drift than small populations.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ- May 21, 2024 - Question 9

Genetic drift, not natural selection, was recently identified as the main factor driving speciation in endangered pupfish species.

About Genetic Drift:

  • It is one of the basic mechanisms of evolution.
  • It takes placewhen the occurrence of variant forms of a genecalled allelesincreases and decreases by chance over timein a population.
  • This occurs due to random sampling and the random events that influence the survival and reproduction of those individuals.
  • These variations in the presence of alleles are measured as changes in allele frequencies.
  • Small populations are more susceptible to genetic drift than large populations, whose larger numbers can buffer the population against chance events.
  • Once it begins, genetic drift will continue until the involved allele is either lost by a population or until it is the only allele present in a population at a particular locus. 
  • Both possibilities decrease the genetic diversity of a population.
  • It could also causeinitially rare allelestobecome much more frequent, and even fixed.
  • Genetic drift is common after population bottlenecks, which are events that drastically decrease the size of a population.
  • In these cases, genetic drift can result in the loss ofrare alleles and decrease the gene pool.
  • Genetic drift can cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.

Hence only statement 1 is correct.
