The answer is Qdenga. It is made by Takeda and was approved by CDSCO on 21 July 2026. Dengvaxia is an older vaccine that India did not approve. Denvax and TDV-1 are not the approved product. Memory hook: Qdenga, CDSCO.

Her 50-second answer beat a computer that had been programmed to solve the same problem.

Her father discovered her gift around age three, while teaching her a card trick that she kept winning.

NCAHP notified a new competency-based curriculum for the Diploma in Medical Laboratory Technology (DMLT) on 1 July 2026.

Allied and healthcare professionals number around 1.3 million in India, nearly 60 percent of the country’s total healthcare workforce, despite an estimated shortfall of over 6 million more.

The NCAHP Act recognises 10 professional categories, covering fields such as medical laboratory science, physiotherapy, and medical radiology.

NCAHP regulates allied and healthcare professionals, a separate and much larger group than the doctors regulated by the National Medical Commission.

The correct answer is roses and bougainvillea. Pal was the founder President of the Rose Society and the Bougainvillea Society, and he bred varieties of both. The ‘orchids and lotuses’ option is wrong because he is not linked to those societies. The ‘marigolds and jasmine’ option is wrong for the same reason. The ‘tulips and chrysanthemums’ option is wrong for the same reason. Memory hook: a wheat breeder who also loved roses.

Pal’s disease-resistant wheat breeding and institutional groundwork, from the 1930s to 1950s, predated and fed into Swaminathan’s 1960s work combining Borlaug’s dwarf wheat genes with India’s own breeding programme.

The correct answer is Director General. Pal became the first Director-General of ICAR in May 1965 and served until January 1972. The ‘Union Agriculture Secretary’ option is wrong because that is a ministry post, not the ICAR post he held. The ‘Chairman of the Governing Body’ option is wrong because the sources do not give that title. The ‘Vice-President’ option is wrong for the same reason. Memory hook: IARI Director in 1950, ICAR Director-General in 1965.

Pal’s 1937 case for systematic germplasm collection eventually grew, through several stages, into the National Bureau of Plant Genetic Resources, established in 1976-77.

NP 809 was the first wheat variety in the world resistant to all three rust diseases simultaneously.

The correct answer is India served as a refuge where the ancient lineage survived. Temperatures fell around 34 million years ago and the plants vanished from many regions. India preserved such tropical lineages. The ‘first evolved in India’ option is wrong because the reports do not say that. The ‘went extinct first’ option is wrong because the lineage survived. The ‘introduced by humans’ option is wrong because the fossils are millions of years older than people. Memory hook: refuge means survivor.

The correct answer is 85-66 million years, from Europe and North America. Older fossils there show the plant’s ancestors spread across the Northern Hemisphere. The ’10-5 million years’ option is wrong because it is far too young. The ’24 million years, from Assam and Odisha’ option is wrong because 24 million years is the age of the Assam leaves. The ‘200-150 million years’ option is wrong because it is far too old. Memory hook: 85 to 66 is the family, 24 is the leaf.

The correct answer is Assam, about 24 million years old. Four leaves came from the Makum Coalfield, Assam, and are at least 24 million years old. The ‘Odisha, about 10 million years’ option is wrong because Odisha is where kewra grows today, not where the leaves were found. The ‘Kerala, about 50 million years’ option is wrong on both state and age. The ‘Rajasthan, about 5 million years’ option is wrong on both. Memory hook: coal in Assam, 24 million years.

The correct answer is Birbal Sahni Institute of Palaeosciences (BSIP), Lucknow. A BSIP team led by Harshita Bhatia and Gaurav Srivastava studied the fossil leaves. The ‘Wadia Institute of Himalayan Geology’ option is wrong because it did not lead this study. The ‘Zoological Survey of India’ option is wrong because it studies animals. The ‘Geological Survey of India’ option is wrong because it did not lead this study either. Memory hook: plant fossils, so Birbal Sahni’s institute.

The correct answer is Rhabdoviridae family, Vesiculovirus genus. The Sapkal review says the virus belongs to the genus Vesiculovirus, family Rhabdoviridae. The Flaviviridae option is wrong because that family holds viruses such as dengue. The Togaviridae option is wrong because that family holds chikungunya. The Bunyaviridae option is wrong because it is not this virus’s family. Memory hook: Rhabdo family, Vesiculo genus.

The 2003-04 outbreak recorded about 322 deaths across the three states, with a case fatality rate of 55-78%. (The other figures describe the 2024 and 2026 outbreaks.)

The correct answer is Children under 15. WHO says the disease affects mostly children under 15 years. The ‘Infants under 2’ option is wrong because the pattern is school-age children. The ‘Adults over 60’ option is wrong because adults are not the main group. The ‘All ages equally’ option is wrong because children are hit most. Memory hook: it is a children’s disease, under 15.

The correct answer is 1965, Maharashtra. The virus was found during a fever outbreak in Maharashtra and isolated from two sick patients. The ‘1975, Gujarat’ option is wrong because Gujarat is linked to later outbreaks. The ‘1955, Andhra Pradesh’ option is wrong because the discovery came a decade later. The ‘1965, Karnataka’ option is wrong because the state was Maharashtra. Memory hook: 1965 and Chandipur, both Maharashtra.

In vitro meat is lab-grown from cell cultures, avoiding the need to raise and slaughter animals.
