Trees derive approximately 90% of their biomass from atmospheric carbon dioxide through photosynthesis, not from soil nutrients. This scientific fact surprises many people. Only about 10% comes from soil minerals and water. The massive trunk, branches, and leaves are mostly built from carbon extracted from air CO2, not from soil.

A single mature tree can produce approximately 260 pounds (about 118 kg) of oxygen annually. A human consumes about 550 liters of oxygen per day. At this rate, one tree's oxygen output could theoretically support 2-4 people's respiratory needs. This estimate varies based on tree species, size, age, and environmental conditions, but the scale is approximately correct.

Trees cool the atmosphere through evapotranspiration - they release water vapor from their leaves, which absorbs heat energy and lowers surrounding temperatures. They also provide shade and reflect solar radiation, further reducing urban heat.

Old Tjikko, a Norway spruce tree in Sweden, is approximately 9,550 years old, making it the world's oldest known living tree. The tree's root system has survived through cloning, with new trunks growing from the same ancient roots over millennia.

Tigers typically have over 100 stripes, and each tiger's stripe pattern is unique - like human fingerprints. The stripes are found on their skin as well as fur, and no two tigers have exactly the same pattern, which helps researchers identify individuals.

There are actually six surviving tiger subspecies: Bengal, Indochinese, Malayan, Siberian (Amur), South China, and Sumatran. Three additional subspecies (Bali, Caspian, and Javan) have gone extinct in the last 100 years. So saying there are only three subspecies is incorrect.

The Siberian tiger is actually the largest of all tiger subspecies, making the statement that the Bengal tiger is the biggest false. While Bengal tigers are large and the most numerous, they are surpassed in size by their Siberian counterparts.

Tigers have incredibly strong leg tendons that can support their weight even after death. There are documented cases of tigers remaining standing on their legs after being shot, due to this anatomical feature. This strength helps them in hunting and jumping.

Tiger stripes are not just in their fur - they are actually in the skin itself. If you shave a tiger's fur, the striped pattern remains visible on the skin. This is because the pigmentation is in the skin, making the stripes a permanent feature of the animal's anatomy.

Godrej was founded by Ardeshir Godrej in 1897. The Godrej family belongs to the Zoroastrian Parsi community, which migrated to India from Persia (modern-day Iran) to avoid religious persecution. The company name reflects this Persian/Iranian heritage of the Parsi community.

This quote appears in Hitler's 'Mein Kampf' and reflects his racist ideology about Jews, whom he falsely claimed were inferior and 'primitive.' The quote exemplifies the antisemitic propaganda that formed part of Nazi ideology. Hitler used such language to justify persecution and genocide.

This is the opening line of the famous Tamil song 'Nilave Malare' from the film 'Pudhiya Varpugal' (1979). The line translates to 'In the stars, brilliance; in the flowers, art; do not look at me, oh eye' - a poetic expression of love and beauty. Option D correctly identifies the song title.

This is the opening line of the Tamil song 'Pookalai Sikkalam' from the film 'Poochudava' (not 'Poochudava' exactly, but phonetically close). The line 'Pagalindri valndu vanden suriyanai thanthaye' translates to 'I survived until today, having given (birth to) the sun' - a powerful maternal statement. Option A is correct.
