South Africa won the triangular series final held in Durban in February 1997, defeating India in the championship match. The series featured South Africa, India, and Zimbabwe, with the host nation emerging victorious on their home soil.

India played their first-ever ODI match at Headingley, Leeds on July 5, 1974 during their tour of England. This marked India's debut in One Day International cricket, a format that would gain immense popularity in the decades to follow.

Ravi Shastri was awarded the 'Champion of Champions' title in the World Championship of Cricket 1985. India defeated Pakistan by 8 wickets in the final, with Shastri's consistent all-round performances throughout the tournament earning him this prestigious individual accolade.

The first ODI match played on Indian soil was at Ahmedabad's Sardar Patel Stadium on November 9, 1981. India faced England in this historic match, which marked the beginning of ODI cricket being hosted in India.

Ajit Wadekar was India's first ODI captain, leading the team in their inaugural ODI against England at Headingley in 1974. A successful left-handed batsman, Wadekar was entrusted with captaincy for this landmark match in Indian cricket history.

Sri Lanka became the first non-Test playing nation to defeat India in an international match during the 1979 World Cup. This victory was significant as Sri Lanka was still an Associate nation at the time, having not yet achieved Test status.

The 1983 Jaipur match between India and Pakistan introduced the rule that no-balls and wides would be debited to the bowler's personal analysis. This meant these extras would negatively affect a bowler's statistics, encouraging greater discipline in bowling.

South Korea celebrates its Liberation Day on August 15th, commemorating the end of Japanese colonial rule in 1945. India also celebrates Independence Day on August 15th (1947), making these two countries that share this independence date. Afghanistan, Denmark, and Mexico do not celebrate independence on August 15th.

The Great Barrier Reef in Australia is the world's largest coral reef system, stretching over 2,300 kilometers. It is visible from space and is home to thousands of species of marine life. The other options are real coral reefs but none match the scale of Australia's Great Barrier Reef.

Coral reefs in mainland India are primarily found in the Gulf of Kutch and Gulf of Mannar. These regions have the right conditions for coral growth. The Gulf of Khambat has extreme tides and is not known for coral reefs. Both Gulfs together form India's main coral reef ecosystems.

Coral polyps extract calcium ions and carbonate ions from seawater and convert them into calcium carbonate (limestone) to build their hard skeletons. This process is called biomineralization and forms coral reefs over time.

Coral reefs provide shelter for fish species and protect coastlines from waves and currents. They do not consume ocean resources or feed on algae.

All four options are valid causes of coral reef degradation. Coral reefs face multiple anthropogenic threats: (A) physical damage from destructive fishing and mining; (B) eutrophication from agricultural runoff causing algal blooms; (C) chemical pollution from petroleum and pesticides; (D) marine debris including plastic and ghost nets. This comprehensive question tests understanding of coral reef conservation issues.

Coral reefs grow very slowly, with an average growth rate of approximately 1 cm per year. This slow growth rate means reef damage from human activities or climate change can take decades or centuries to recover naturally. The 1 cm/year figure is a standard benchmark in marine biology.

Not all corals form reefs. While reef-building corals (hermatypic corals) create the massive reef structures we associate with coral ecosystems, there are many solitary corals (ahermatypic corals) that live independently and do not contribute to reef formation. These solitary corals can be found in various marine environments, from deep waters to temperate seas.

Coral reefs require specific conditions to thrive: warm, clear, shallow tropical waters with temperatures between 23-29°C. They are predominantly found between 30°N and 30°S latitudes, which corresponds to tropical and subtropical regions. This is because reef-building corals have a symbiotic relationship with zooxanthellae algae that need sunlight for photosynthesis. False would be incorrect as this geographical distribution is a fundamental fact about coral reefs.

The pattern counts the number of letters in the English word for each number. For example: 9 is 'nine' (4 letters), 21 is 'twenty one' (9 letters), and 16 is 'sixteen' (7 letters). Notice that 100 being 7 suggests 'hundred' only, which is consistent with counting letters in the number word.

Tom's speed of 37.2822715 mph converts to exactly 60 km/h (since 1 mile ≈ 1.609 km). Both Bob and Tom travel at the same speed of 60 km/h from the same starting point at the same time. Therefore, they will reach the destination at the same time - 6 a.m.

This is a trick question - ALL months have 28 days. February has exactly 28 days (except 29 in leap years), but every other month (January, March, April, May, June, July, August, September, October, November, December) also contains 28 days as part of their 30 or 31 days.
