Problem: Bermuda:

The most famous escapee was the Boer prisoner of war Captain Fritz Joubert Duquesne who was serving a life sentence for "conspiracy against the British government and on (the charge of) espionage.". On the night of 25 June 1902, Duquesne slipped out of his tent, worked his way over a barbed-wire fence, swam 1.5 miles (2.4 km) past patrol boats and bright spot lights, through storm-wracked, shark infested waters, using a distant lighthouse for navigation until he arrived ashore on the main island. From there he escaped to the port of St. George's and a week later, he stowed away on a boat heading to Baltimore, Maryland. He settled in the US and later became a spy for Germany in both World Wars. In 1942, Col. Duquesne was arrested by the FBI for leading the Duquesne Spy Ring, which still to this day the largest espionage case in the history of the United States.

Problem: In 1883, salt water taffy was conceived in Atlantic City by David Bradley. The traditional story is that Bradley's shop was flooded after a major storm, soaking his taffy with salty Atlantic Ocean water.

Bradley's mother was in the back of the store when the sale was made, and loved the name, and so salt water taffy was born.
Who did Bradley sell salt water taffy to for the first time?

Context and question: In 1970, the New Haven Black Panther trials took place, the largest and longest trials in Connecticut history. Black Panther Party co-founder Bobby Seale and ten other Party members were tried for murdering an alleged informant. Beginning on May Day, the city became a center of protest for 12,000 Panther supporters, college students, and New Left activists (including Jean Genet, Benjamin Spock, Abbie Hoffman, Jerry Rubin, and John Froines), who amassed on the New Haven Green, across the street from where the trials were being held. Violent confrontations between the demonstrators and the New Haven police occurred, and several bombs were set off in the area by radicals. The event became a rallying point for the New Left and critics of the Nixon Administration.
How many attended the trials of the Black Panther in 1970?
Answer: 12,000

Question: The ranging signals are based on the CDMA principle and have complex structure typical of Galileo or modernized GPS. Similar to the other GNSS, there will be two levels of positioning service: open and restricted (military). The public service shall be available globally to general users. When all the currently planned GNSS systems are deployed, the users will benefit from the use of a total constellation of 75+ satellites, which will significantly improve all the aspects of positioning, especially availability of the signals in so-called urban canyons. The general designer of the COMPASS navigation system is Sun Jiadong, who is also the general designer of its predecessor, the original BeiDou navigation system.
Is there an answer to this question: How many satellites will the COMPASS navigation system use?

Answer: 75+ satellites

The history of biodiversity during the Phanerozoic (the last 540 million years), starts with rapid growth during the Cambrian explosiona period during which nearly every phylum of multicellular organisms first appeared. Over the next 400 million years or so, invertebrate diversity showed little overall trend, and vertebrate diversity shows an overall exponential trend. This dramatic rise in diversity was marked by periodic, massive losses of diversity classified as mass extinction events. A significant loss occurred when rainforests collapsed in the carboniferous. The worst was the Permian-Triassic extinction event, 251 million years ago. Vertebrates took 30 million years to recover from this event.
In which event did the vertebrates collapse in the carboniferous?
A:
unanswerable
