- Clean energy, decarbonisation & infrastructure
- Taxation & anti-corruption
- Fair & resilient trade
Choose the correct answer using the codes given below:
[A] Only 1, 2 & 3
[B] Only 2, 3 & 4
[C] Only 1, 3 & 4
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: D [1, 2, 3 & 4]
Notes:- The US at the recently held Quad Summit in Tokyo launched the Indo-Pacific Economic Framework (IPEF) to offer the region better alternatives to fulfil its developmental goals. The IPEF framework has four pillars: Supply-chain resilience; Clean energy, decarbonisation & infrastructure; Taxation & anti-corruption; Fair & resilient trade.
- The Indo-Pacific Economic Framework (IPEF) is a US-led initiative that aims to strengthen economic partnership among participating countries to enhance resilience, sustainability, inclusiveness, economic growth, fairness, and competitiveness in the Indo-Pacific region.
- The IPEF member countries together represent 40% of the world GDP.
2. Respiratory Syncytial Virus causes which of the following health conditions?
- Bronchitis
- Otitis media
- Pneumonia
Choose the correct answer using the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: C [Only 1 & 3]
Notes:- Respiratory Syncytial Virus is a common respiratory virus. It is characterized by its highly contagious nature i.e. it has a high potential to infect people. It exacerbated the seasonal lung infection. It commonly infects children especially under 2 to 6 years of age. In most of the cases it has symptoms like the common cold but in advanced stages it converts into pneumonia and bronchiolitis.
- Otitis media is inflammation or infection located in the middle ear. Otitis media can occur as a result of a cold, sore throat, or respiratory infection.
- Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs.
3. Consider the following statements:
- The mantle is made up of 45% oxygen, 21% silicon, and 23% magnesium.
- Density of outer core is less than the mantle.
- Earth’s inner core rotates slightly faster relative to the rotation of the surface.
Which of the statements given above are correct?
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: C [Only 1 & 3]
Notes:- The Earth’s mantle forms about 83 per cent of the earth’s volume and holds 67% of the earth’s mass. It extends from Moho’s discontinuity to a depth of 2,900 km.
- The density of the upper mantle varies between 2.9 g/cm3and 3.3 g/cm3.
- The lower mantle extends beyond the asthenosphere. It is in a solid state.
- The density ranges from 3.3 g/cm3to 5.7 g/cm3 in the lower mantle.
- The mantle is composed of silicate rocks that are rich in iron and magnesium relative to the overlying crust.
- Regarding its constituent elements, the mantle is made up of 45% oxygen, 21% silicon, and 23% magnesium (OSM).
- The outer core is composed of iron mixed with nickel nife) and trace amounts of lighter elements.
- The density of the outer core ranges from9 g/cm3to 12.2 g/cm3.
- Since this layer can transmit shear waves (transverse seismic waves), it is solid. (When P-waves strike the outer core – inner core boundary, they give rise to S-waves).
- Earth’s inner core rotates slightly faster relative to the rotation of the surface.
- The solid inner core is too hot to hold a permanent magnetic field.
