Answer: Option D - Assessment of scientific research impact

Explanation:

• The H-Index (Hirsch Index) and Impact Factor (IF) are key benchmarks for assessing the quality and impact of scientific research.
• The H-Index measures a researcher's productivity and citation impact, while the Impact Factor evaluates the average number of citations received by articles in a journal.
• These metrics help determine the credibility of research publications and their influence in the global academic community.

Answer: Option B - To expand public Wi-Fi access across India, promoting Digital India and rural connectivity

Explanation:

• The PM-WANI scheme aims to expand public Wi-Fi access across India, promoting Digital India, affordable internet, and rural connectivity.
• It enables Public Data Offices (PDOs) to set up and operate Wi-Fi hotspots without a license, making internet services more accessible.
• The scheme does not focus on disaster alerts or language translation but rather on bridging the digital divide, especially in rural and underserved areas.

Answer: Option C - Microsoft

Explanation:

• Microsoft developed Majorana 1, a quantum computing chip designed to solve industrial-scale problems efficiently.
• It is based on Majorana particles, which are unique as they act as their own antiparticles.
• This breakthrough could significantly advance quantum computing by improving stability and reducing errors.
• Microsoft aims to make quantum computing more practical within years, competing with companies like Google and IBM in the race for quantum supremacy.

Answer: Option C - Loss of symbiotic algae due to environmental stress

Explanation:

• Coral bleaching occurs when environmental stress, such as rising sea temperatures, pollution, or high solar radiation, forces corals to expel their symbiotic algae (zooxanthellae).
• These algae provide corals with nutrients and their vibrant colors. Without them, corals turn white and become vulnerable to disease and death.
• While factors like ocean acidification and sedimentation impact coral health, the primary cause of bleaching is the loss of symbiotic algae due to stress.
