question:
Passage: The climate of Cork, like the rest of Ireland, is mild and changeable with abundant rainfall and a lack of temperature extremes. Cork lies in plant Hardiness zone 9b. Met Éireann maintains a climatological weather station at Cork Airport, a few kilometres south of the city. It should be noted that the airport is at an altitude of 151 metres (495 ft) and temperatures can often differ by a few degrees between the airport and the city itself. There are also smaller synoptic weather stations at UCC and Clover Hill.
answer:
How is the rest of Ireland climate different than Cork's?


question:
Passage: Dunn and Dunn focused on identifying relevant stimuli that may influence learning and manipulating the school environment, at about the same time as Joseph Renzulli recommended varying teaching strategies. Howard Gardner identified a wide range of modalities in his Multiple Intelligences theories. The Myers-Briggs Type Indicator and Keirsey Temperament Sorter, based on the works of Jung, focus on understanding how people's personality affects the way they interact personally, and how this affects the way individuals respond to each other within the learning environment. The work of David Kolb and Anthony Gregorc's Type Delineator follows a similar but more simplified approach.
answer:
 Who discredited identifying stimuli that can influence learning?


question:
Passage: Although its PlayStation predecessors had been very dominant against the competition and were hugely profitable for Sony, PlayStation 3 had an inauspicious start, and Sony chairman and CEO Sir Howard Stringer initially could not convince investors of a turnaround in its fortunes. The PS3 lacked the unique gameplay of the more affordable Wii which became that generation's most successful console in terms of units sold. Furthermore, PS3 had to compete directly with Xbox 360 which had a market head start, and as a result the platform no longer had exclusive titles that the PS2 enjoyed such as the Grand Theft Auto and Final Fantasy series (regarding cross-platform games, Xbox 360 versions were generally considered superior in 2006, although by 2008 the PS3 versions had reached parity or surpassed), and it took longer than expected for PS3 to enjoy strong sales and close the gap with Xbox 360. Sony also continued to lose money on each PS3 sold through 2010, although the redesigned "slim" PS3 has cut these losses since then.
answer:

What was PlayStation 4's toughest competitor in the video game market?
