Historical Dates and Firsts

When writing dates with month-day-year format, a comma is placed between the day and the year: 'February 12, 1809'. No comma is needed between the month and the day. The other options either omit this required comma or place it incorrectly between month and day.

In 1924, during a close approach of Mars, astronomer David Todd convinced the US military to maintain radio silence to listen for potential signals from Mars - one of the earliest SETI attempts. The 1970s dates are too late for this historical event.

'Jana Gana Mana' was first sung on December 27, 1911, at the Calcutta Session of the Indian National Congress. It was written by Rabindranath Tagore in 1911. The anthem was officially adopted by the Constituent Assembly of India in 1950, much later than its first performance.

GNU project was founded by Richard Stallman in 1984 to develop a complete Unix-like operating system. Linux kernel was created later by Linus Torvalds in 1991. The term GNU/Linux emphasizes that the system combines GNU tools with Linux kernel. Andrew Tannenbaum created Minix, not Linux.

Project Tiger was launched on April 1, 1973, to protect the Bengal tiger from extinction. It was initiated at Jim Corbett National Park in Uttarakhand, which was the first tiger reserve under this project.

Sun Microsystems was founded in 1982 by Vinod Khosla, Andy Bechtolsheim, and Scott McNeely. The company became a major Silicon Valley tech company before being acquired by Oracle. 1970, 1975, and 1985 are incorrect founding years.

Second Generation computers (1956-1965) used transistors instead of vacuum tubes. First Generation was 1949-1955, Third Generation was 1965-1970 (integrated circuits), and Fourth Generation was 1970 onwards (microprocessors).

The First Round Table Conference opened in London on 12 November 1930, organized by the British government to discuss constitutional reforms for India. It ran until 19 January 1931 and was attended by representatives from various Indian political groups, though the Indian National Congress boycotted it.

The first recorded Olympic Games were held in 776 BC in Olympia, Greece. This marked the beginning of the ancient Olympic festival that continued until 393 AD. The games were part of a religious festival honoring Zeus.

The first television sets were commercially sold in 1928, with regular broadcasts beginning in the late 1920s. The 1930s and 1940s saw television adoption increase after this initial introduction. The question lists 1928 as the first option, which aligns with historical records.

The first US elevated railroad began service in New York City in 1867, but not on July 3rd. The other three events (Washington taking command in 1775, News at 10 premiere in 1967, Statue of Liberty relighting in 1986) did occur on July 3rd. This is a historical date verification question.

Find the event misdated to April 3rd. The Beatles' 'Can't Buy Me Love' reached #1 on April 4, 1964 (not April 3rd). The other events are correctly dated: gold price record (April 3, 1974), French nuclear test (April 3, 1976), and first portable cell phone call (April 3, 1973).

Find the event NOT on May 3rd. The US never had a 20¢ coin in circulation in 1878 - the 20-cent piece was minted 1875-1878 but was discontinued, not 'stopped minting on May 3, 1878.' The other events are correctly dated to May 3rd: DC incorporation (1802), Kasparov-Deep Blue (May 3, 1997), and Oklahoma tornado (May 3, 1999).
