While the exact survival time varies by individual, medical consensus suggests that humans can typically survive without food for 2-4 weeks if adequately hydrated. The 14-day limit represents a conservative medical estimate. Survival beyond 30 days without food is extremely rare and would require exceptional circumstances.

Burkina Faso was indeed called Upper Volta (Haute-Volta in French) during the colonial period and after independence until 1984. The name referred to the Volta River basin. The country was renamed Burkina Faso by President Thomas Sankara, meaning 'Land of Incorruptible People.'

Francis Galton developed the first intelligence tests in the late 19th century, pioneering the field of psychometrics. His work on mental testing and correlation laid foundations for modern IQ testing. Kepler, Descartes, and Copernicus were astronomers and philosophers who lived centuries before intelligence testing emerged.

VDIS (Voluntary Disclosure of Income Scheme) was a tax amnesty scheme launched by the Indian government in 1997.

The Labrador Current is a cold oceanic current that flows south from the Arctic Ocean along the coast of Labrador and Newfoundland in eastern Canada. It meets the warm Gulf Stream near the Grand Banks, creating fog and rich fishing grounds. The Kuroshio and Gulf Stream are warm currents, while the Falklands Current flows near South America.

Tropical moist forests (rainforests) harbor the greatest biodiversity of plant and animal species on Earth. The Amazon rainforest alone contains about 10% of all known species. The stable climate, abundant rainfall, and complex vertical structure create numerous ecological niches. Temperate forests, polluted rivers, and deserts have significantly lower biodiversity.

Soil pH measures the acidity or alkalinity of soil on a scale of 0-14, with 7 being neutral. It indicates the concentration of hydrogen ions in the soil solution, which determines acid content. pH affects nutrient availability and microbial activity. Fertility, iron-lime content, and water retention are important soil properties but are not measured by pH.

The normal human body temperature is approximately 37°C, which equals 98.6°F. Option C (36.9°C) is the closest to this standard value. Options A and D are too high in Celsius, while option B incorrectly uses Fahrenheit value as Celsius.

Eutrophication is the process where water bodies become overly enriched with nutrients (especially nitrogen and phosphorus), leading to excessive algae growth and oxygen depletion. None of the given options A, B, or C correctly describe this process.

The UN has six official languages: English, French, Chinese, Russian, Spanish, and Arabic. Option B correctly lists five of these six languages (it omits Arabic). Options A, C, and D include incorrect languages like German, Hindi, and Japanese.

Human females have two X chromosomes (XX), while males have one X and one Y (XY). An unfertilized egg (ovum) always contains one X chromosome from the mother. Sperm can carry either X or Y chromosome, determining the baby's sex.

Tej Bahadur Sapru was a prominent lawyer who defended INA (Indian National Army) prisoners during the famous Red Fort trials in 1945. The INA trials were held for soldiers of the Indian National Army who were captured by the British.

Adrenaline (epinephrine) is the primary hormone released by adrenal glands during stressful situations, preparing the body for 'fight or flight' response. It increases heart rate, blood pressure, and energy availability. Noradrenaline also plays a role but adrenaline is the primary hormone.

The Salt March (Dandi March) began on March 12, 1930, from Sabarmati Ashram and concluded at Dandi on April 6, 1930. Gandhi and his followers marched 240 miles to make salt in defiance of the British salt tax. The question asks where it started from - Dandi was the destination.

M.S. Subbulakshmi was the first Indian to perform at the United Nations General Assembly in 1966. She was invited by the UN and performed to raise funds for UNICEF. She was a legendary Carnatic vocalist.

Surface tension is the cohesive force between liquid molecules that causes water droplets to minimize their surface area. A sphere has the minimum surface area for a given volume, which is why small water droplets naturally form spherical shapes.

Cassette tapes use magnetic tape coated with ferromagnetic powder (such as ferric oxide or chromium dioxide). This coating allows sound to be recorded and played back through electromagnetic encoding and pickup by the tape recorder head.

DNA fingerprinting is a forensic technique that analyzes unique patterns in an individual's DNA. It is widely used in criminal investigations to identify suspects, link suspects to crime scenes, or exonerate innocent people based on biological evidence like hair, blood, or saliva.

World Population Day is observed annually on July 11th. It was established by the United Nations Development Programme in 1989 to raise awareness about population issues and their relation to development and the environment.
