ANS:C - Only II and III follow

Explanation: Since the school has introduced the scheme without receiving any grant, it needs to pool up the funds and make adequate arrangements to keep the scheme going. So, only II and III follow.

ANS:B - Vacuum residue

The most ideal feedstock for the 'coking' process used for the manufacture of petroleum coke is vacuum residue.

Explanation:

• Coking Process: This is a thermal cracking process used to convert heavy residual oils into lighter products and petroleum coke. The process operates at high temperatures to break down large hydrocarbon molecules.
• Vacuum Residue: This is the heavy residue left after vacuum distillation of crude oil. It contains large, complex hydrocarbon molecules that are ideal for coking.

Characteristics of Ideal Feedstock:

• High Molecular Weight: Vacuum residue consists of large molecules that break down under coking conditions to form lighter hydrocarbons and solid coke.
• High Carbon Content: This residue has a high carbon-to-hydrogen ratio, which is essential for producing high-quality petroleum coke.
• Low Value as Fuel: Vacuum residue has limited use as a fuel due to its high viscosity and low volatility, making it more suitable for conversion into valuable products like petroleum coke.

Unsuitable Feedstocks:

• Naphtha: This is a light, low-boiling fraction used primarily as a feedstock for petrochemical processes or as a blending component in gasoline. It lacks the high molecular weight needed for effective coking.
• Light Gas Oil: This is a distillate fraction that is typically used as diesel or heating oil. It is not heavy enough for the coking process.
• Diesel: This is another distillate product, primarily used as a fuel for diesel engines. Like light gas oil, it is not suitable for coking due to its lower molecular weight and boiling range.

ANS:D - China

China has confirmed that a balloon identified by Washington and Bogota flying over Latin America is Chinese after a similar device was shot down by the United States.

ANS:D - New Zealand

The NASA PREFIRE polar mission will be launched from the Vandenberg Space Force Base in the United States. This mission is designed to advance our understanding of Earth's polar regions by studying the interactions between ice sheets, sea ice, and the atmosphere. The launch site at Vandenberg, known for its strategic location and capability to support a wide range of satellite missions, provides a favorable platform for placing the PREFIRE satellite into its intended orbit. The mission aims to gather crucial data on polar ice dynamics, which is essential for improving climate models and assessing the impacts of climate change on polar environments. By launching from Vandenberg Space Force Base, NASA leverages the base's infrastructure and expertise to ensure a successful deployment of PREFIRE, ultimately contributing to enhanced environmental monitoring and scientific research.

ANS:C - Venezuela

The country that became the first in the world to lose all its glaciers is the Maldives. This significant environmental milestone highlights the severe impacts of climate change on the Maldives, a low-lying island nation in the Indian Ocean. The loss of glaciers, which were crucial for maintaining freshwater supplies and regulating sea levels, underscores the broader consequences of global warming, particularly for vulnerable island nations. As sea levels rise and temperatures increase, the Maldives faces heightened risks of coastal erosion, flooding, and other climate-related challenges. The disappearance of glaciers in the Maldives serves as a stark reminder of the urgent need for global action to mitigate climate change and adapt to its effects, emphasizing the importance of international cooperation and sustainable practices to address the environmental crisis.

ANS:A - China
