[Ans] What fad item was invented by Gary Dahl in 1975?

Step 1 : Introduction to the question "What fad item was invented by Gary Dahl in 1975?"

In 1975, Gary Dahl launched the sale of the pet rock which quickly turned him into a multi-millionaire. My Pet Rock sold for $3.95, and creator Gary Dahl unloaded more than five million of the igneous invertebrates in six months. He walked away with a cool $15 million. Dahl imported the rocks from Mexico, packaged them in a cardboard box that mimicked a pet carrier – complete with air holes, and a bed of straw. The fad only lasted about six months, and ended after a short increase in sales during the Christmas season of December 1975.

[Answer] 7. Which athlete, who was knighted in 1975 for his achievements in athletics, was the first man ever to run a sub-four minute mile?

...1. Chris Chataway 2. Roger Bannister 3. Chris Brasher 4. John Landy May 1954: Brasher and Chataway were friends of Bannister, and he employed them to set the early pace and ensure that he ran the first 3/4 of a mile fast enough. The Australian John Landy was Bannister's main rival, the other man who experts believed was capable of beating the four minute barrier. Indeed he did so less than a month later. The two men met at the British Empire Games in July of that year in what was billed as the "Mile of the Century". Bannister won, confirming his position as world number one. Astonishingly, Bannister achieved all this while undertaking full-time medical studies at Oxford University. He later became a respected neurologist.
