Input: Article: Enlisted members of the USAF have pay grades from E-1 (entry level) to E-9 (senior enlisted). While all USAF military personnel are referred to as Airmen, the term also refers to the pay grades of E-1 through E-4, which are below the level of non-commissioned officers (NCOs). Above the pay grade of E-4 (i.e., pay grades E-5 through E-9) all ranks fall into the category of NCO and are further subdivided into "NCOs" (pay grades E-5 and E-6) and "Senior NCOs" (pay grades E-7 through E-9); the term "Junior NCO" is sometimes used to refer to staff sergeants and technical sergeants (pay grades E-5 and E-6).

Now answer this question: What is the lowest pay grade in the USAF?

Output: E-1 (entry level)

Input: Article: In 2004 and 2007, the American Customer Satisfaction Index (ACSI) survey found that Comcast had the worst customer satisfaction rating of any company or government agency in the country, including the Internal Revenue Service. The ACSI indicates that almost half of all cable customers (regardless of company) have registered complaints, and that cable is the only industry to score below 60 in the ACSI. Comcast's Customer Service Rating by the ACSI surveys indicate that the company's customer service has not improved since the surveys began in 2001. Analysis of the surveys states that "Comcast is one of the lowest scoring companies in ACSI. As its customer satisfaction eroded by 7% over the past year, revenue increased by 12%." The ACSI analysis also addresses this contradiction, stating that "Such pricing power usually comes with some level of monopoly protection and most cable companies have little competition at the local level. This also means that a cable company can do well financially even though its customers are not particularly satisfied."

Now answer this question: Comcast's customer service was rated worse than what government organization?

Output: the Internal Revenue Service

Input: Article: Vinson Massif, the highest peak in Antarctica at 4,892 m (16,050 ft), is located in the Ellsworth Mountains. Antarctica contains many other mountains, on both the main continent and the surrounding islands. Mount Erebus on Ross Island is the world's southernmost active volcano. Another well-known volcano is found on Deception Island, which is famous for a giant eruption in 1970. Minor eruptions are frequent and lava flow has been observed in recent years. Other dormant volcanoes may potentially be active. In 2004, a potentially active underwater volcano was found in the Antarctic Peninsula by American and Canadian researchers.

Now answer this question: In what mountainous area of Antarctica is Vinson Massif?

Output:
Ellsworth Mountains
