Q: Question: "What was the cornerstone of Dell's business model?" 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:
A: supply chain efficiencies

Question: Question: "A cheating face is a type of?" Context: "Illegal pinning methods include using the ropes for leverage and hooking the opponent's clothing, which are therefore popular cheating methods for heels, unless certain stipulations make such an advantage legal. Such pins as these are rarely seen by the referee (as they have to see if their shoulders are down) and are subsequently often used by heels and on occasion by cheating faces to win matches. Even if it is noticed, it is rare for such an attempt to result in a disqualification (see below), and instead it simply results in nullification of the pin attempt, so the heel wrestler rarely has anything to lose for trying it, anyway." Answer:
Answer: wrestler

[Q]: Question: "The name the "La Brea Tar Pits" is ironic because it is made up of what?" Context: "Asphalt/bitumen can sometimes be confused with "coal tar", which is a visually similar black, thermoplastic material produced by the destructive distillation of coal. During the early and mid-20th century when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of tar to macadam roads led to the word tarmac, which is now used in common parlance to refer to road-making materials. However, since the 1970s, when natural gas succeeded town gas, asphalt/bitumen has completely overtaken the use of coal tar in these applications. Other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar. Pitch is another term sometimes used at times to refer to asphalt/bitumen, as in Pitch Lake." Answer:
****
[A]: natural bitumen rather than tar

input: Please answer the following: Question: "If there is hydrogen present, what is not?" Context: "In the absence of atmospheric oxygen (O2), in deep geological conditions prevailing far away from Earth atmosphere, hydrogen (H2) is produced during the process of serpentinization by the anaerobic oxidation by the water protons (H+) of the ferrous (Fe2+) silicate present in the crystal lattice of the fayalite (Fe2SiO4, the olivine iron-endmember). The corresponding reaction leading to the formation of magnetite (Fe3O4), quartz (SiO2) and hydrogen (H2) is the following:" Answer:
++++++++++
output: atmospheric oxygen (O2)
