Problem: Please answer a question about the following article about Macintosh:
The current Mac product family uses Intel x86-64 processors. Apple introduced an emulator during the transition from PowerPC chips (called Rosetta), much as it did during the transition from Motorola 68000 architecture a decade earlier. The Macintosh is the only mainstream computer platform to have successfully transitioned to a new CPU architecture, and has done so twice. All current Mac models ship with at least 8 GB of RAM as standard other than the 1.4 GHz Mac Mini, MacBook Pro (without Retina Display), and MacBook Air. Current Mac computers use ATI Radeon or nVidia GeForce graphics cards as well as Intel graphics built into the main CPU. All current Macs (except for the MacBook Pro without Retina Display) do not ship with an optical media drive that includes a dual-function DVD/CD burner. Apple refers to this as a SuperDrive. Current Macs include two standard data transfer ports: USB and Thunderbolt (except for the MacBook (2015 version), which only has a USB-C port and headphone port). MacBook Pro, iMac, MacBook Air, and Mac Mini computers now also feature the "Thunderbolt" port, which Apple says can transfer data at speeds up to 10 gigabits per second. USB was introduced in the 1998 iMac G3 and is ubiquitous today, while FireWire is mainly reserved for high-performance devices such as hard drives or video cameras. Starting with the then-new iMac G5, released in October 2005, Apple started to include built-in iSight cameras on appropriate models, and a media center interface called Front Row that can be operated by an Apple Remote or keyboard for accessing media stored on the computer. Front Row has been discontinued as of 2011, however, and the Apple Remote is no longer bundled with new Macs.
When was the iMac G5 released?
A: October 2005
Problem: Please answer a question about the following article about Gamal Abdel Nasser:
The Egyptian singer Umm Kulthum hosted a public celebration for the officers' return despite reservations from the royal government, which had been pressured by the British to prevent the reception. The apparent difference in attitude between the government and the general public increased Nasser's determination to topple the monarchy. Nasser had also felt bitter that his brigade had not been relieved despite the resilience it displayed. He started writing his book Philosophy of the Revolution during the siege.
What group opposed the celebration of Nasser's brigade's return?
A: royal government
Problem: Please answer a question about the following article about Phonology:
In 1968 Noam Chomsky and Morris Halle published The Sound Pattern of English (SPE), the basis for generative phonology. In this view, phonological representations are sequences of segments made up of distinctive features. These features were an expansion of earlier work by Roman Jakobson, Gunnar Fant, and Morris Halle. The features describe aspects of articulation and perception, are from a universally fixed set, and have the binary values + or −. There are at least two levels of representation: underlying representation and surface phonetic representation. Ordered phonological rules govern how underlying representation is transformed into the actual pronunciation (the so-called surface form). An important consequence of the influence SPE had on phonological theory was the downplaying of the syllable and the emphasis on segments. Furthermore, the generativists folded morphophonology into phonology, which both solved and created problems.
When was The Sound Pattern of English published?
A: 1968
Problem: Please answer a question about the following article about Ashkenazi Jews:
A 2010 study by Bray et al., using SNP microarray techniques and linkage analysis found that when assuming Druze and Palestinian Arab populations to represent the reference to world Jewry ancestor genome, between 35 to 55 percent of the modern Ashkenazi genome can possibly be of European origin, and that European "admixture is considerably higher than previous estimates by studies that used the Y chromosome" with this reference point. Assuming this reference point the linkage disequilibrium in the Ashkenazi Jewish population was interpreted as "matches signs of interbreeding or 'admixture' between Middle Eastern and European populations". On the Bray et al. tree, Ashkenazi Jews were found to be a genetically more divergent population than Russians, Orcadians, French, Basques, Italians, Sardinians and Tuscans. The study also observed that Ashkenazim are more diverse than their Middle Eastern relatives, which was counterintuitive because Ashkenazim are supposed to be a subset, not a superset, of their assumed geographical source population. Bray et al. therefore postulate that these results reflect not the population antiquity but a history of mixing between genetically distinct populations in Europe. However, it's possible that the relaxation of marriage prescription in the ancestors of Ashkenazim that drove their heterozygosity up, while the maintenance of the FBD rule in native Middle Easterners have been keeping their heterozygosity values in check. Ashkenazim distinctiveness as found in the Bray et al. study, therefore, may come from their ethnic endogamy (ethnic inbreeding), which allowed them to "mine" their ancestral gene pool in the context of relative reproductive isolation from European neighbors, and not from clan endogamy (clan inbreeding). Consequently, their higher diversity compared to Middle Easterners stems from the latter's marriage practices, not necessarily from the former's admixture with Europeans.
Were the Ashkenazim thought to be a subset or superset of their assumed geographical source population?
A:
Ashkenazim are supposed to be a subset, not a superset
