Problem: Apple has generally dominated the premium PC market, having a 91 percent market share for PCs priced at more than $1,000 in 2009, according to NPD. The Macintosh took 45 percent of operating profits in the PC industry during Q4 2012, compared to 13 percent for Dell, seven percent for Hewlett Packard, six percent for Lenovo and Asus, and one percent for Acer. While sales of the Macintosh have largely held steady, in comparison to Apple's sales of the iPhone and iPad which increased significantly during the 2010s, Macintosh computers still enjoy high margins on a per unit basis, with the majority being their MacBooks that are focused on the ultraportable niche that is the most profitable and only growing segment of PCs. It also helped that the Macintosh lineup is simple, updated on a yearly schedule, and consistent across both Apple retail stores, and authorized resellers where they have a special "store within a store" section to distinguish them from Windows PCs. In contrast, Windows PC manufacturers generally have a wide range of offerings, selling only a portion through retail with a full selection on the web, and often with limited-time or region-specific models. The Macintosh ranked third on the "list of intended brands for desktop purchases" for the 2011 holiday season, then moved up to second in 2012 by displacing Hewlett Packard, and in 2013 took the top spot ahead of Dell.
According to NPD, who has generally dominated the premium PC market?
The answer is the following: Apple

$100,000

Input: Rajasthan
In recent decades, the literacy rate of Rajasthan has increased significantly. In 1991, the state's literacy rate was only 38.55% (54.99% male and 20.44% female). In 2001, the literacy rate increased to 60.41% (75.70% male and 43.85% female). This was the highest leap in the percentage of literacy recorded in India (the rise in female literacy being 23%). At the Census 2011, Rajasthan had a literacy rate of 67.06% (80.51% male and 52.66% female). Although Rajasthan's literacy rate is below the national average of 74.04% and although its female literacy rate is the lowest in the country, the state has been praised for its efforts and achievements in raising male and female literacy rates.

Input: Article: Hunting-gathering was the common human mode of subsistence throughout the Paleolithic, but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples.

Now answer this question: Where do you find groups that represent pristine conditions?

Output: in uncontacted peoples

Problem: The low mechanical complexity of hydraulic elevators in comparison to traction elevators makes them ideal for low rise, low traffic installations. They are less energy efficient as the pump works against gravity to push the car and its passengers upwards; this energy is lost when the car descends on its own weight. The high current draw of the pump when starting up also places higher demands on a building's electrical system. There are also environmental concerns should the lifting cylinder leak fluid into the ground.
What else contributes to a higher demand from the electrical system?
The answer is the following:
The high current draw of the pump when starting up
