Question: Read this and answer the question

Egypt also hosts an unknown number of refugees and asylum seekers, estimated to be between 500,000 and 3 million. There are some 70,000 Palestinian refugees, and about 150,000 recently arrived Iraqi refugees, but the number of the largest group, the Sudanese, is contested.[nb 1] The once-vibrant and ancient Greek and Jewish communities in Egypt have almost disappeared, with only a small number remaining in the country, but many Egyptian Jews visit on religious or other occasions and tourism. Several important Jewish archaeological and historical sites are found in Cairo, Alexandria and other cities.

Approximately how many rufugees and asylum seekers are in Egypt?
Answer: between 500,000 and 3 million


Problem: The Soviet Zond spacecraft was not yet ready for piloted circumlunar missions in 1968, after five unsuccessful and partially successful automated test launches: Cosmos 146 on March 10, 1967; Cosmos 154 on April 8, 1967; Zond 1967A September 27, 1967; Zond 1967B on November 22, 1967. Zond 4 was launched on March 2, 1968, and successfully made a circumlunar flight. After its successful flight around the Moon, Zond 4 encountered problems with its Earth reentry on March 9, and was ordered destroyed by an explosive charge 15,000 meters (49,000 ft) over the Gulf of Guinea. The Soviet official announcement said that Zond 4 was an automated test flight which ended with its intentional destruction, due to its recovery trajectory positioning it over the Atlantic Ocean instead of over the USSR.
Where was the Zond 4 over when it was destroyed by an explosion?
The answer is the following: Gulf of Guinea


The current US fleet of Nimitz-class carriers will be followed into service (and in some cases replaced) by the ten-ship Gerald R. Ford class. It is expected that the ships will be more automated in an effort to reduce the amount of funding required to staff, maintain and operate its supercarriers. The main new features are implementation of Electromagnetic Aircraft Launch System (EMALS) (which replace the old steam catapults) and unmanned aerial vehicles. With the deactivation of USS Enterprise in December 2012 (decommissioning scheduled for 2016), the U.S. fleet comprises 10 active supercarriers. On 24 July 2007, the House Armed Services Seapower subcommittee recommended seven or eight new carriers (one every four years). However, the debate has deepened over budgeting for the $12–14.5 billion (plus $12 billion for development and research) for the 100,000 ton Gerald R. Ford-class carrier (estimated service 2016) compared to the smaller $2 billion 45,000 ton America-class amphibious assault ships able to deploy squadrons of F-35B of which one is already active, another is under construction and nine more are planned.
Which feature of the new ships will replace the old steam catapults?
Electromagnetic Aircraft Launch System (EMALS)
