Question: Passage: The Very high-speed Backbone Network Service (vBNS) came on line in April 1995 as part of a National Science Foundation (NSF) sponsored project to provide high-speed interconnection between NSF-sponsored supercomputing centers and select access points in the United States. The network was engineered and operated by MCI Telecommunications under a cooperative agreement with the NSF. By 1998, the vBNS had grown to connect more than 100 universities and research and engineering institutions via 12 national points of presence with DS-3 (45 Mbit/s), OC-3c (155 Mbit/s), and OC-12c (622 Mbit/s) links on an all OC-12c backbone, a substantial engineering feat for that time. The vBNS installed one of the first ever production OC-48c (2.5 Gbit/s) IP links in February 1999 and went on to upgrade the entire backbone to OC-48c.

Answer: What were select locations connected to? 


Question: Passage: The U.S. Army currently consists of 10 active divisions as well as several independent units. The force is in the process of contracting after several years of growth. In June 2013, the Army announced plans to downsize to 32 active combat brigade teams by 2015 to match a reduction in active duty strength to 490,000 soldiers. Army Chief of Staff Raymond Odierno has projected that by 2018 the Army will eventually shrink to "450,000 in the active component, 335,000 in the National Guard and 195,000 in U.S. Army Reserve."

Answer: How many divisions are there in the U.S. Navy?


Question: Passage: The Super Slim model of PS3 has received positive reviews. Gaming website Spong praised the new Super Slim's quietness, stating "The most noticeable noise comes when the drive seeks a new area of the disc, such as when starting to load a game, and this occurs infrequently." They added that the fans are quieter than that of Slim, and went on to praise the new smaller, lighter size. Criticism was placed on the new disc loader, stating: "The cover can be moved by hand if you wish, there's also an eject button to do the work for you, but there is no software eject from the triangle button menus in the Xross Media Bar (XMB) interface. In addition, you have to close the cover by hand, which can be a bit fiddly if it's upright, and the PS3 won't start reading a disc unless you do [close the cover]." They also said there is no real drop in retail price.

Answer:
What quality of the PS2 Super Slim was the website Spong excited about?
