Input: Read this: The town's first significant defences were likely erected due to commercial interests, following the temporary seizure of St. John's by the Dutch admiral Michiel de Ruyter in June 1665. The inhabitants were able to fend off a second Dutch attack in 1673, when this time it was defended by Christopher Martin, an English merchant captain. Martin landed six cannons from his vessel, the Elias Andrews, and constructed an earthen breastwork and battery near chain Rock commanding the Narrows leading into the harbour. With only twenty-three men, the valiant Martin beat off an attack by three Dutch warships. The English government planned to expand these fortifications (Fort William) in around 1689, but actual construction didn't begin until after the French admiral Pierre Le Moyne d'Iberville captured and destroyed the town in the Avalon Peninsula Campaign (1696). When 1500 English reinforcements arrived in late 1697 they found nothing but rubble where the town and fortifications had stood.
Question: How many Dutch warships were fended of by Christopher Martin in 1673?

QUES: As early as 1934, Popper wrote of the search for truth as "one of the strongest motives for scientific discovery." Still, he describes in Objective Knowledge (1972) early concerns about the much-criticised notion of truth as correspondence. Then came the semantic theory of truth formulated by the logician Alfred Tarski and published in 1933. Popper writes of learning in 1935 of the consequences of Tarski's theory, to his intense joy. The theory met critical objections to truth as correspondence and thereby rehabilitated it. The theory also seemed, in Popper's eyes, to support metaphysical realism and the regulative idea of a search for truth.

Whose theory of truth did Alfred Tarski read in 1935?

QUES: Organic cotton is generally understood as cotton from plants not genetically modified and that is certified to be grown without the use of any synthetic agricultural chemicals, such as fertilizers or pesticides. Its production also promotes and enhances biodiversity and biological cycles. In the United States, organic cotton plantations are required to enforce the National Organic Program (NOP). This institution determines the allowed practices for pest control, growing, fertilizing, and handling of organic crops. As of 2007, 265,517 bales of organic cotton were produced in 24 countries, and worldwide production was growing at a rate of more than 50% per year.
How much sythetic cotton was produced worldwide in 2007?

On 25 and 26 April, May and Taylor appeared on the eleventh series of American Idol at the Nokia Theatre, Los Angeles, performing a Queen medley with the six finalists on the first show, and the following day performed "Somebody to Love" with the 'Queen Extravaganza' band. Queen were scheduled to headline Sonisphere at Knebworth on 7 July 2012 with Adam Lambert before the festival was cancelled. Queen's final concert with Freddie Mercury was in Knebworth in 1986. Brian May commented, "It's a worthy challenge for us, and I'm sure Adam would meet with Freddie's approval." Queen expressed disappointment at the cancellation and released a statement to the effect that they were looking to find another venue. It was later announced that Queen + Adam Lambert would play two shows at the Hammersmith Apollo, London on 11 and 12 July 2012. Both shows sold out within 24 hours of tickets going on open sale. A third London date was scheduled for 14 July. On 30 June, Queen + Lambert performed in Kiev, Ukraine at a joint concert with Elton John for the Elena Pinchuk ANTIAIDS Foundation. Queen also performed with Lambert on 3 July 2012 at Moscow's Olympic Stadium, and on 7 July 2012 at the Municipal Stadium in Wroclaw, Poland.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did Queen perform with Adam Lambert on 3 July 2012?
Ah, so.. Moscow's Olympic Stadium
