Input: Read this: Nintendo staff members reported that demo users complained about the difficulty of the control scheme. Aonuma realized that his team had implemented Wii controls under the mindset of "forcing" users to adapt, instead of making the system intuitive and easy to use. He began rethinking the controls with Miyamoto to focus on comfort and ease.[q] The camera movement was reworked and item controls were changed to avoid accidental button presses.[r] In addition, the new item system required use of the button that had previously been used for the sword. To solve this, sword controls were transferred back to gestures—something E3 attendees had commented they would like to see. This reintroduced the problem of using a right-handed swing to control a left-handed sword attack. The team did not have enough time before release to rework Link's character model, so they instead flipped the entire game—everything was made a mirror image.[s] Link was now right-handed, and references to "east" and "west" were switched around. The GameCube version, however, was left with the original orientation. The Twilight Princess player's guide focuses on the Wii version, but has a section in the back with mirror-image maps for GameCube users.[t]
Question: What features did Aonuma work to improve after Miyamoto's complaints?

Output: unanswerable


Input: Read this: The party's decision-making bodies on a national level formally include the National Executive Committee (NEC), Labour Party Conference and National Policy Forum (NPF)—although in practice the Parliamentary leadership has the final say on policy. The 2008 Labour Party Conference was the first at which affiliated trade unions and Constituency Labour Parties did not have the right to submit motions on contemporary issues that would previously have been debated. Labour Party conferences now include more "keynote" addresses, guest speakers and question-and-answer sessions, while specific discussion of policy now takes place in the National Policy Forum.
Question: What includes less keynote addresses now?

Output: unanswerable


Input: Read this: Brain tissue consumes a large amount of energy in proportion to its volume, so large brains place severe metabolic demands on animals. The need to limit body weight in order, for example, to fly, has apparently led to selection for a reduction of brain size in some species, such as bats. Most of the brain's energy consumption goes into sustaining the electric charge (membrane potential) of neurons. Most vertebrate species devote between 2% and 8% of basal metabolism to the brain. In primates, however, the percentage is much higher—in humans it rises to 20–25%. The energy consumption of the brain does not vary greatly over time, but active regions of the cerebral cortex consume somewhat more energy than inactive regions; this forms the basis for the functional brain imaging methods PET, fMRI, and NIRS. The brain typically gets most of its energy from oxygen-dependent metabolism of glucose (i.e., blood sugar), but ketones provide a major alternative source, together with contributions from medium chain fatty acids (caprylic and heptanoic acids), lactate, acetate, and possibly amino acids.
Question: Other sources than glucose that provide energy to the brain are what?

Output: ketones


Input: Read this: After Fidel Castro rose to power in Cuba in 1959, many wealthy Cubans sought refuge in Miami, further increasing the population. The city developed businesses and cultural amenities as part of the New South. In the 1980s and 1990s, South Florida weathered social problems related to drug wars, immigration from Haiti and Latin America, and the widespread destruction of Hurricane Andrew. Racial and cultural tensions were sometimes sparked, but the city developed in the latter half of the 20th century as a major international, financial, and cultural center. It is the second-largest U.S. city (after El Paso, Texas) with a Spanish-speaking majority, and the largest city with a Cuban-American plurality.
Question: In what year did Fidel Castro lose Cuba?

Output:
unanswerable
