Answer:  Option C- As part of innovative vector control strategies to reduce mosquito-borne diseases.

Explanation:

• Wolbachia bacteria have been in the news due to their use in vector control programs aimed at reducing the transmission of mosquito-borne diseases like dengue, Zika, and chikungunya.
• By infecting mosquitoes with Wolbachia, which reduces their ability to transmit these viruses, scientists hope to lower disease rates and improve public health.
• This approach represents a novel and promising method in disease control.

Answer:  Option B - An 11-year cycle characterized by alternating phases of high and low solar activity.

Explanation:

• A solar cycle lasts about 11 years, during which the Sun's magnetic activity fluctuates between periods of low activity (solar minimum) and high activity (solar maximum).
• This cycle affects sunspot numbers, solar flares, and coronal mass ejections, influencing space weather and impacting the Earth's magnetosphere and ionosphere.
• Understanding this cycle is crucial for space weather forecasting.

Answer:  Option C - It was used as a burial site and an astronomical observatory.

Explanation:

• Recent research supports that Stonehenge primarily functioned as a burial site, evident from the remains found in nearby barrows, and as an astronomical observatory.
• The monument’s alignment with celestial events, such as solstices and equinoxes, suggests its use in tracking astronomical phenomena.
• This dual purpose highlights its significance in both ceremonial and observational capacities in ancient society.

Answer:  Option C - Its ability to emit potent neutrons and high cost.

Explanation:

• Californium is particularly valuable and dangerous due to its potent neutron emission, which makes it useful for neutron radiography and other specialized applications.
• Its high cost, approximately Rs 17 crore per gram, further highlights its rarity and value.
• The combination of its significant neutron-emitting properties and high market value contributes to both its usefulness and potential risks.
