Extract the answer to the question from the following context. Question: Why did Dell have a reputation of not being an innovator in the mid-2000's? Context: Dell had a reputation as a company that relied upon supply chain efficiencies to sell established technologies at low prices, instead of being an innovator. By the mid-2000s many analysts were looking to innovating companies as the next source of growth in the technology sector. Dell's low spending on R&D relative to its revenue (compared to IBM, Hewlett Packard, and Apple Inc.)which worked well in the commoditized PC marketprevented it from making inroads into more lucrative segments, such as MP3 players and later mobile devices. Increasing spending on R&D would have cut into the operating margins that the company emphasized. Dell had done well with a horizontal organization that focused on PCs when the computing industry moved to horizontal mix-and-match layers in the 1980s, but by the mid-2000 the industry shifted to vertically integrated stacks to deliver complete IT solutions and Dell lagged far behind competitors like Hewlett Packard and Oracle.

Answer: low spending on R&D

Extract the answer to the question from the following context. Question: What was Antarctica once connected to? Context: Antarctica continued to become more isolated and finally developed a permanent ice cap. Mountain building in western North America continued, and the Alps started to rise in Europe as the African plate continued to push north into the Eurasian plate, isolating the remnants of Tethys Sea. A brief marine incursion marks the early Oligocene in Europe. There appears to have been a land bridge in the early Oligocene between North America and Europe since the faunas of the two regions are very similar. During the Oligocene, South America was finally detached from Antarctica and drifted north toward North America. It also allowed the Antarctic Circumpolar Current to flow, rapidly cooling the continent.
