Input: Article: In 2007, it was discovered that the upper troposphere of Neptune's south pole was about 10 K warmer than the rest of its atmosphere, which averages approximately 73 K (200 C). The temperature differential is enough to let methane, which elsewhere is frozen in the troposphere, escape into the stratosphere near the pole. The relative "hot spot" is due to Neptune's axial tilt, which has exposed the south pole to the Sun for the last quarter of Neptune's year, or roughly 40 Earth years. As Neptune slowly moves towards the opposite side of the Sun, the south pole will be darkened and the north pole illuminated, causing the methane release to shift to the north pole.

Now answer this question: How much warmer is Neptune's south pole to the rest of it's atmosphere?

Output: 10 K

Input: Article: The geography of Southampton is influenced by the sea and rivers. The city lies at the northern tip of the Southampton Water, a deep water estuary, which is a ria formed at the end of the last Ice Age. Here, the rivers Test and Itchen converge. The Testwhich has salt marsh that makes it ideal for salmon fishingruns along the western edge of the city, while the Itchen splits Southampton in twoeast and west. The city centre is located between the two rivers.

Now answer this question: Which river is excellent for salmon fishing?

Output: Test

Input: Article: Apple did not develop the iPod software entirely in-house, instead using PortalPlayer's reference platform based on two ARM cores. The platform had rudimentary software running on a commercial microkernel embedded operating system. PortalPlayer had previously been working on an IBM-branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface under the direct supervision of Steve Jobs. As development progressed, Apple continued to refine the software's look and feel. Starting with the iPod Mini, the Chicago font was replaced with Espy Sans. Later iPods switched fonts again to Podium Sansa font similar to Apple's corporate font, Myriad. iPods with color displays then adopted some Mac OS X themes like Aqua progress bars, and brushed metal meant to evoke a combination lock. In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).

Now answer this question: Which company worked with Apple in creating the user interface for the iPod?

Output:
Pixo
