Q) Consider the following statements about earthquakes:

The movement of glaciers can cause earthquakes by changing the Earth’s crust.
The ‘Modified Mercalli Intensity’ scale takes into account the height of a building when measuring earthquake intensity.
At present, less than half of India’s land is under threat of moderate to severe seismic hazards.

How many of the statements given above is/are correct?

Only one
Only two
All three
None

Explanation:

Statement 1 is correct: An earthquake is a sudden release of energy in the Earth’s crust that creates seismic waves. The focus, also known as the hypocentre, is the point within the Earth where an earthquake originates. Epicentre is the point on the Earth’s surface directly above the focus or source of an earthquake. The movement of the Earth’s tectonic plates can cause earthquakes when the plates interact along plate boundaries. The movement of glaciers can cause earthquakes as they advance or retreat and cause changes in the Earth’s crust.
Statement 2 is correct: The most commonly used scale for measuring earthquake intensity is the Modified Mercalli Intensity (MMI) scale, which ranges from I to XII. The MMI scale takes into account factors such as the type of building construction, the height of the building, and the distance from the earthquake’s epicenter.
Statement 3 is incorrect: As per the current seismic zone map of the country, over 59% of India’s land area is under threat of moderate to severe seismic hazard. The entire Himalayan belt is considered prone to hazardous earthquakes of magnitude exceeding 8.0. Example: 1897 Shillong Earthquake (M8.7); 1905 Kangra (M8.0); 1950 Assam-Tibet earthquake etc (M8.6). Himalayas is the region of convergence of Indian and Eurasian plates. The Indian plate is moving at a speed of one centimetre per year towards the north and northeastern direction.

Q) With reference to Asian Infrastructure Investment Bank (AIIB), consider the following statements:

India is one of the founding members and largest borrower of the AIIB.

Explanation:

Statements 1 and 2 are correct: The Asian Infrastructure Investment Bank (AIIB) is a multilateral development bank with a mission to improve social and economic outcomes in Asia. It was formed in 2016. AIIB aims at investing in sustainable infrastructure and other productive sectors today, it aims to connect people, services and markets that over time will impact the lives of billions and build a better future. India is a Founding Member of AIIB. India also has the largest project portfolio within AIIB. India is by far the largest borrower as of November 2022.
Statement 3 is incorrect: There are more than 100 members now. China is the largest shareholder with 26.61 % voting shares in the bank followed by India (7.6%), Russia (6.01%) and Germany (4.2 %). AIIB has been projected as an “Asian tool” to deal with such challenges that have stunted the growth prospects of several Asian economies.

Q) With reference to Primary Amoebic Meningoencephalitis (PAM), consider the following statements:

PAM is a genetic disease caused by the addition of a chromosome to DNA.
PAM damages the brain tissue and causes swelling of the brain.

Which of the statements given above is/are correct?

1 only
2 only
Both 1 and 2
Neither 1 nor 2

Explanation:

Statement 1 is incorrect: Primary amoebic meningoencephalitis (PAM) is a rare infection of the central nervous system caused by infection with Naegleria fowleri, a microscopic amoeba commonly called a “brain-eating amoeba.” Naegleria fowleri is a free-living ameba (a single-celled living organism that is too small to be seen without a microscope). Naegleria fowleri lives in warm fresh water and soil around the world. Naegleria fowleridoes not live in salt water, like the ocean.
Statement 2 is correct: PAM typically occurs when people swim in bodies of warm freshwater (such as lakes and streams/rivers) where Naegleria fowleri is present. Naegleria fowleri infects people when water containing the amoeba enters the body through the nose. It destroys the brain tissue and causes swelling of the brain. Naegleria fowleri can NOT be spread from person to person. Symptoms of PAM are headache, fever, nausea, vomiting, stiff neck, confusion, lack of attention to people and surroundings, loss of balance, seizures and hallucinations. PAM is treated with a combination of drugs that often include amphotericin B, azithromycin, fluconazole, rifampin, miltefosine, and dexamethasone.
