The school has been previously criticized for its lack of diversity, and The Princeton Review ranks the university highly among schools at which "Alternative Lifestyles [are] Not an Alternative." It has also been commended by some diversity oriented publications; Hispanic Magazine in 2004 ranked the university ninth on its list of the top–25 colleges for Latinos, and The Journal of Blacks in Higher Education recognized the university in 2006 for raising enrollment of African-American students. With 6,000 participants, the university's intramural sports program was named in 2004 by Sports Illustrated as the best program in the country, while in 2007 The Princeton Review named it as the top school where "Everyone Plays Intramural Sports."

Sentence: One of the main driving forces in the growth of the University was its football team, the Notre Dame Fighting Irish. Knute Rockne became head coach in 1918. Under Rockne, the Irish would post a record of 105 wins, 12 losses, and five ties. During his 13 years the Irish won three national championships, had five undefeated seasons, won the Rose Bowl in 1925, and produced players such as George Gipp and the "Four Horsemen". Knute Rockne has the highest winning percentage (.881) in NCAA Division I/FBS football history. Rockne's offenses employed the Notre Dame Box and his defenses ran a 7–2–2 scheme. The last game Rockne coached was on December 14, 1930 when he led a group of Notre Dame all-stars against the New York Giants in New York City.

Ex Input:
Sentence: The advertised battery life on most models is different from the real-world achievable life. For example, the fifth generation 30 GB iPod is advertised as having up to 14 hours of music playback. An MP3.com report stated that this was virtually unachievable under real-life usage conditions, with a writer for MP3.com getting on average less than 8 hours from an iPod. In 2003, class action lawsuits were brought against Apple complaining that the battery charges lasted for shorter lengths of time than stated and that the battery degraded over time. The lawsuits were settled by offering individuals either US$50 store credit or a free battery replacement. 
Question: How many hours of real-time battery life did the 5th-generation iPod test at, compared to its advertised 14 hours?

Ex Output:

8 hours
