Problem: Child labour:

In 1998, UNICEF reported that Ivory Coast farmers used enslaved children many from surrounding countries. In late 2000 a BBC documentary reported the use of enslaved children in the production of cocoathe main ingredient in chocolate in West Africa. Other media followed by reporting widespread child slavery and child trafficking in the production of cocoa. In 2001, the US State Department estimated there were 15,000 child slaves cocoa, cotton and coffee farms in the Ivory Coast, and the Chocolate Manufacturers Association acknowledged that child slavery is used in the cocoa harvest.[not in citation given][better source needed]

How many child slaves were reported in cocoa, coffee and cotton farms?

A: 15,000

Problem: Hanover:

In September 1941, through the "Action Lauterbacher" plan, a ghettoisation of the remaining Hanoverian Jewish families began. Even before the Wannsee Conference, on 15 December 1941, the first Jews from Hanover were deported to Riga. A total of 2,400 people were deported, and very few survived. During the war seven concentration camps were constructed in Hanover, in which many Jews were confined. Of the approximately 4,800 Jews who had lived in Hannover in 1938, fewer than 100 were still in the city when troops of the United States Army arrived on 10 April 1945 to occupy Hanover at the end of the war.[citation needed] Today, a memorial at the Opera Square is a reminder of the persecution of the Jews in Hanover. After the war a large group of Orthodox Jewish survivors of the nearby Bergen-Belsen concentration camp settled in Hanover.

When did the Russian army arrive to occupy Hanover?

Problem: Southampton:

Southampton has always been a port, and the docks have long been a major employer in the city. In particular, it is a port for cruise ships; its heyday was the first half of the 20th century, and in particular the inter-war years, when it handled almost half the passenger traffic of the UK. Today it remains home to luxury cruise ships, as well as being the largest freight port on the Channel coast and fourth largest UK port by tonnage, with several container terminals. Unlike some other ports, such as Liverpool, London, and Bristol, where industry and docks have largely moved out of the city centres leaving room for redevelopment, Southampton retains much of its inner-city industry. Despite the still active and expanding docklands to the west of the city centre, further enhanced with the opening of a fourth cruise terminal in 2009, parts of the eastern docks have been redeveloped; the Ocean Village development, which included a local marina and small entertainment complex, is a good example. Southampton is home to the headquarters of both the Maritime and Coastguard Agency and the Marine Accident Investigation Branch of the Department for Transport in addition to cruise operator Carnival UK.

About how much of UK's passenger traffic did Southampton handle during the inter-war period?

A: half

Problem: Aircraft carrier:

Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.

Which visual landing aids have provided information on proper glide slope since the late 1940's?
