Answer: c

Explanation:

The explosions and the boom sounds heard by the residents of Boston recently could be the result of “a rather significant bolide/meteor entering the atmosphere.”

About Bolide:

• A bolide is a type of large, exceptionally bright meteor that often explodes in the upper atmosphere, producing a bright flash of light and occasionally fragmented meteorites reaching the ground.
• Bolides are distinguished from regular meteors by their greater brightness and more dramatic visual effects.
• Bolides can also produce loud booms.
• Bolides are more common than many people realize, with several occurring each year, though most go unnoticed or happen over remote areas.
• Studying bolides can provide valuable information about the composition and structure of meteoroids, as well as insights into the processes that occur during atmospheric entry.

What is a Meteor?

• A space rock that has not entered the Earth’s atmosphere is usually referred to as a meteoroid or asteroid.
• Once in the Earth’s atmosphere, the rock traveling at very high velocities encounters friction from the atmosphere, resulting in a fireball that is then referred to as a meteor.
• Meteors that reach the ground are then called meteorites.

Hence option c is the correct answer.

Answer: b

Explanation:

In Borpada village in Madhya Pradesh’s Jhabua district, residents revived the Bhil tradition of Halma to clean and restore a public well.

About Halma Tradition:

• Halma is an old collective tradition practiced by the Bhil tribal community of Madhya Pradesh.
• Its direct meaning is: to work together without wages or contract, sustained by mutual obligation and belonging.
• At its heart, Halma represents a profound tradition of voluntary collective labour.
• The roots of this tradition reach back to an era when these communities had neither large resources, nor government support, nor a marketplace. What they had was one another.
• When an individual or family faces a significant task, be it constructing a home, repairing agricultural embankments, restoring a water body, or organizing a major communal event, they invoke Halma.
• In response, scores, sometimes hundreds, of community members assemble, bringing their own tools, food, and labour, and work collectively until the task is accomplished.
• There is no formal leader and no grand announcement. There is only work, done side by side.
• No monetary compensation is expected. Participation arises not from obligation enforced by external authority but from ethical commitment, ancestral values, and the assurance that when needed, the favor will be returned.
• In recent years, Halma has been revitalized to address common challenges such as:
  • Restoration of traditional water bodies
  • Afforestation of barren hills
  • Construction of contour trenches for rainwater conservation
  • Revitalization of biodiversity and soil health

Hence only statement 2 is correct.

Explanation:

The Indian government is likely to introduce a mandate permitting blending isobutanol with diesel by the end of this year. 

• It is also called isobutyl alcohol, is an alcohol with the chemical formula C₄H₁₀O and one of the four isomers of butanol.
• Properties of Isobutanol:
  • It is a clear, colorless liquid with a characteristic odor. 
  • It is only moderately soluble in water.
  • It is very flammable and has a flash point that is only slightly above normal room temperatures. 
  • Its vapors are heavier than air and can spread unnoticed along the ground. 
  • It can be made from ethanol using fermentation processes.
• Applications of Isobutanol:
  • It is used as a solvent in the flavor, fragrance, pharmaceutical, and pesticide industries and as a chemical manufacturing ingredient for products such as lacquer, paint strippers, paint primer, and craft paints.
  • It is an approved food additive and is also naturally occurring in some foods and many alcoholic beverages. 
  • Isobutanol may also be used as a biofuel because, like ethanol, it can be manufactured from plants.
  • It possesses some favorable properties that make it an attractive fuel for internal combustion engines. 
  • Isobutanol is less corrosive than ethanol and is much less hygroscopic, which enables it to be transported using the existing fuel infrastructure.

Hence both statements are correct.
