Historical Dates and Firsts

The Eiffel Tower has 1792 steps from the ground to the top. This is a well-documented fact about one of the world's most famous landmarks. The other options (1634, 1978, 1587) are not the correct number of steps to reach the summit.

The first email system was created by Ray Tomlinson in 1971, with the first email sent over ARPANET. The year 1972 is widely cited as when email became more established and widely used on the network. This predates the modern Internet but represents the foundation of electronic mail communication.

The Diners Club card, considered the first credit card, was introduced by Frank McNamara and Ralph Schneider in 1950. This revolutionary concept allowed customers to pay for meals at multiple restaurants without carrying cash, pioneering the modern credit card system.

Alexander Bain patented the fax machine in 1842 (patent received in 1843). This makes 1842 the correct year for the invention of the facsimile machine, which worked by scanning documents and transmitting them via telegraph.

Christopher Latham Sholes developed the QWERTY keyboard layout in 1873, with the typewriter being manufactured in 1875. This year marks when the practical keyboard as we know it became available commercially.

Chelsea Football Club was founded in 1905 at The Rising Sun pub in West London. The club was established by Gus Mears after acquiring the Stamford Bridge athletics ground. Option A (1901) is incorrect as the ground was acquired then but the club wasn't formed until 1905. Options C and D are not the correct founding years.

The first commercial transatlantic telephone service began on January 7, 1927, connecting New York and London via radio-telephone technology. This established the first regular voice communication across the Atlantic Ocean.

'2 States - The Story of My Marriage' was published on October 8, 2009. This novel explores the cultural challenges in an inter-community marriage between a Tamil girl and a Punjabi boy, based partly on Bhagat's own life.

Chetan Bhagat's third novel 'The 3 Mistakes of My Life' was published in 2008, continuing his exploration of contemporary Indian youth experiences. The book dealt with entrepreneurship, friendship, and religious tensions in Gujarat, further cementing his position as a leading voice in Indian popular fiction.

'One Night @ the Call Center,' Chetan Bhagat's sophomore novel, was released in 2005, one year after his debut 'Five Point Someone' (2004). This publication timeline established his early pattern of regular releases and built on the momentum of his first book's success.

The first GSLV launch (GSLV-D1) occurred on April 18, 2001. This marked a significant milestone in India's space program, developing indigenous capability to launch heavier satellites into geosynchronous orbit.

The first-ever Test match was played between Australia and England from March 15 to March 19, 1877, at the Melbourne Cricket Ground. Australia won this inaugural Test match by 45 runs. The match began on March 15, 1877, which makes option B the correct answer. This historic contest laid the foundation for Test cricket, which has now become the oldest and most prestigious format of the game.

Chelsea first reached the FA Cup final in 1915, where they lost to Sheffield United 3-0 at Old Trafford. This was their first appearance in the prestigious tournament's final match. The other dates (1907, 1937, 1950) are not associated with Chelsea's first FA Cup final appearance.

June has only 30 days, so '31st June' is a non-existent date. February 2000 was a leap year (29 days), April 1998 has 30 days (so 29th is valid), and August always has 31 days. The impossibility of the date makes it the odd one out.
