Problem: San Diego:

From the start of the 20th century through the 1970s, the American tuna fishing fleet and tuna canning industry were based in San Diego, "the tuna capital of the world". San Diego's first tuna cannery was founded in 1911, and by the mid-1930s the canneries employed more than 1,000 people. A large fishing fleet supported the canneries, mostly staffed by immigrant fishermen from Japan, and later from the Portuguese Azores and Italy whose influence is still felt in neighborhoods like Little Italy and Point Loma. Due to rising costs and foreign competition, the last of the canneries closed in the early 1980s.

How many jobs were created by the mid-1930s thanks to San Diego's tuna cannery that was developed in 1921?

A: unanswerable


Problem: Dissolution of the Soviet Union:

On July 1, 1985, Gorbachev promoted Eduard Shevardnadze, First Secretary of the Georgian Communist Party, to full member of the Politburo, and the following day appointed him minister of foreign affairs, replacing longtime Foreign Minister Andrei Gromyko. The latter, disparaged as "Mr Nyet" in the West, had served for 28 years as Minister of Foreign Affairs. Gromyko was relegated to the largely ceremonial position of Chairman of the Presidium of the Supreme Soviet (officially Soviet Head of State), as he was considered an "old thinker." Also on July 1, Gorbachev took the opportunity to dispose of his main rival by removing Grigory Romanov from the Politburo, and brought Boris Yeltsin and Lev Zaikov into the CPSU Central Committee Secretariat.

When did Eduard Shevardnadze gain full membership in the Politburo?
---
A: July 1, 1985


Problem: USB:

The newer micro-USB receptacles are designed for a minimum rated lifetime of 10,000 cycles of insertion and removal between the receptacle and plug, compared to 1,500 for the standard USB and 5,000 for the mini-USB receptacle. Features intended to accomplish include, a locking device was added and the leaf-spring was moved from the jack to the plug, so that the most-stressed part is on the cable side of the connection. This change was made so that the connector on the less expensive cable would bear the most wear instead of the more expensive micro-USB device. However the idea that these changes did in fact make the connector more durable in real world use has been widely disputed, with many contending that they are in fact, much less durable.

After a leaf-spring was moved from jack to the plug, the most stressed part was found where?
---
A: on the cable side of the connection

Solomon (1942–2007), an American philosopher who contributed to the theories on the philosophy of emotions with books such as What Is An Emotion?: Classic and Contemporary Readings (Oxford, 2003); Peter Goldie (1946–2011), a British philosopher who specialized in ethics, aesthetics, emotion, mood and character; Nico Frijda (1927–2015), a Dutch psychologist who advanced the theory that human emotions serve to promote a tendency to undertake actions that are appropriate in the circumstances, detailed in his book The Emotions (1986).
