Problem: Uranium:

During the Cold War between the Soviet Union and the United States, huge stockpiles of uranium were amassed and tens of thousands of nuclear weapons were created using enriched uranium and plutonium made from uranium. Since the break-up of the Soviet Union in 1991, an estimated 600 short tons (540 metric tons) of highly enriched weapons grade uranium (enough to make 40,000 nuclear warheads) have been stored in often inadequately guarded facilities in the Russian Federation and several other former Soviet states. Police in Asia, Europe, and South America on at least 16 occasions from 1993 to 2005 have intercepted shipments of smuggled bomb-grade uranium or plutonium, most of which was from ex-Soviet sources. From 1993 to 2005 the Material Protection, Control, and Accounting Program, operated by the federal government of the United States, spent approximately US $550 million to help safeguard uranium and plutonium stockpiles in Russia. This money was used for improvements and security enhancements at research and storage facilities. Scientific American reported in February 2006 that in some of the facilities security consisted of chain link fences which were in severe states of disrepair. According to an interview from the article, one facility had been storing samples of enriched (weapons grade) uranium in a broom closet before the improvement project; another had been keeping track of its stock of nuclear warheads using index cards kept in a shoe box.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the Hundred Years' War a French attack (1340) burned a manor house and took some prisoners, but failed to get into the town. In 1403 the town was burned by Breton raiders. In the late fifteenth century a 'castle quadrate' was constructed close to the area now known as The Barbican; it included four round towers, one at each corner, as featured on the city coat of arms. The castle served to protect Sutton Pool, which is where the fleet was based in Plymouth prior to the establishment of Plymouth Dockyard. In 1512 an Act of Parliament was passed for further fortifying Plymouth, and a series of fortifications were then built, including defensive walls at the entrance to Sutton Pool (across which a chain would be extended in time of danger). Defences on St Nicholas Island also date from this time, and a string of six artillery blockhouses were built, including one on Fishers Nose at the south-eastern corner of the Hoe. This location was further strengthened by the building of a fort (later known as Drake's Fort) in 1596, which itself went on to provide the site for the Citadel, established in the 1660s (see below).
Before Plymouth dockyard was built, where was the fleet located?
A: Sutton Pool

Context and question: Private CBC affiliates are not as common as they were in the past, as many such stations have been purchased either by the CBC itself or by Canwest Global or CHUM Limited, respectively becoming E! or A-Channel (later A, now CTV Two) stations. One private CBC affiliate, CHBC-TV in Kelowna, joined E! (then known as CH) on February 27, 2006. When a private CBC affiliate reaffiliates with another network, the CBC has normally added a retransmitter of its nearest O&O station to ensure that CBC service is continued. However, due to an agreement between CHBC and CFJC-TV in Kamloops, CFJC also disaffiliated from the CBC on February 27, 2006, but no retransmitters were installed in the licence area. Former private CBC affiliates CKPG-TV Prince George and CHAT-TV Medicine Hat disaffiliated on August 31, 2008 and joined E!, but the CBC announced it will not add new retransmitters to these areas. Incidentally, CFJC, CKPG and CHAT are all owned by an independent media company, Jim Pattison Group. With the closure of E! and other changes in the media landscape, several former CBC affiliates have since joined City or Global, or closed altogether.
Which CBC affiliate joined E! in February 2006?
Answer: CHBC-TV in Kelowna

Question: Universal's 1936 Show Boat (released a little over a month later) became a critical and financial success, it was not enough to save the Laemmles' involvement with the studio. They were unceremoniously removed from the company they had founded. Because the Laemmles personally oversaw production, Show Boat was released (despite the takeover) with Carl Laemmle and Carl Laemmle Jr.'s names on the credits and in the advertising campaign of the film. Standard Capital's J. Cheever Cowdin had taken over as president and chairman of the board of directors, and instituted severe cuts in production budgets. Gone were the big ambitions, and though Universal had a few big names under contract, those it had been cultivating, like William Wyler and Margaret Sullavan, left.
Is there an answer to this question: What position did J. Cowdin Cheever hold?

Answer: unanswerable

Problem: Iran:

Iran's climate ranges from arid or semiarid, to subtropical along the Caspian coast and the northern forests. On the northern edge of the country (the Caspian coastal plain) temperatures rarely fall below freezing and the area remains humid for the rest of the year. Summer temperatures rarely exceed 29 C (84.2 F). Annual precipitation is 680 mm (26.8 in) in the eastern part of the plain and more than 1,700 mm (66.9 in) in the western part. United Nations Resident Coordinator for Iran Gary Lewis has said that "Water scarcity poses the most severe human security challenge in Iran today".

According to Gary Lewis of the UN, what is the most pressing human security challenge in Iran?
---
A:
Water scarcity
