Problem: Dryer and rockier uplands and ridges are occupied by oak-chestnut type forests dominated by a variety of oaks (Quercus spp.), hickories (Carya spp.) and, in the past, by the American chestnut (Castanea dentata). The American chestnut was virtually eliminated as a canopy species by the introduced fungal chestnut blight (Cryphonectaria parasitica), but lives on as sapling-sized sprouts that originate from roots, which are not killed by the fungus. In present-day forest canopies chestnut has been largely replaced by oaks.
What trees replaced chestnut trees?

Answer: oaks

Rajasthan is famous for its forts, carved temples, and decorated havelis, which were built by Rajput kings in pre-Muslim era Rajasthan.[citation needed] Rajasthan's Jaipur Jantar Mantar, Mehrangarh Fort and Stepwell of Jodhpur, Dilwara Temples, Chittorgarh Fort, Lake Palace, miniature paintings in Bundi, and numerous city palaces and haveli's are part of the architectural heritage of India.

Context and question: Erik Erikson (1902-1994) became one of the earliest psychologists to take an explicit interest in identity. The Eriksonian framework rests upon a distinction among the psychological sense of continuity, known as the ego identity (sometimes identified simply as "the self"); the personal idiosyncrasies that separate one person from the next, known as the personal identity; and the collection of social roles that a person might play, known as either the social identity or the cultural identity. Erikson's work, in the psychodynamic tradition, aimed to investigate the process of identity formation across a lifespan. Progressive strength in the ego identity, for example, can be charted in terms of a series of stages in which identity is formed in response to increasingly sophisticated challenges. The process of forming a viable sense of identity for the culture is conceptualized as an adolescent task, and those who do not manage a resynthesis of childhood identifications are seen as being in a state of 'identity diffusion' whereas those who retain their initially given identities unquestioned have 'foreclosed' identities (Weinreich & Saunderson 2003 p7-8). On some readings of Erikson, the development of a strong ego identity, along with the proper integration into a stable society and culture, lead to a stronger sense of identity in general. Accordingly, a deficiency in either of these factors may increase the chance of an identity crisis or confusion (Cote & Levine 2002, p. 22).
In what tradition is Erikson's work to track identity formation throughout a lifetime?
Answer: the psychodynamic tradition


Question: Following the release of Intel-based Macs, third-party platform virtualization software such as Parallels Desktop, VMware Fusion, and VirtualBox began to emerge. These programs allow users to run Microsoft Windows or previously Windows-only software on Macs at near native speed. Apple also released Boot Camp and Mac-specific Windows drivers that help users to install Windows XP or Vista and natively dual boot between Mac OS X and Windows. Though not condoned by Apple, it is possible to run the Linux operating system using Boot camp or other virtualization workarounds. Unlike most PCs, however, Macs are unable to run many legacy PC operating systems. In particular, Intel-based macs lack the A20 gate.
Is there an answer to this question: What do Macs have that makes them unable to run many legacy PC operating systems?

Answer: unanswerable

Many regions in Russia were affected by the Soviet famine of 1932–1933: Volga; Central Black Soil Region; North Caucasus; the Urals; the Crimea; part of Western Siberia; and the Kazak ASSR. With the adoption of the 1936 Soviet Constitution on December 5, 1936, the size of the RSFSR was significantly reduced. The Kazakh ASSR and Kirghiz ASSR were transformed into the Kazakh and Kirghiz Soviet Socialist Republics. The Karakalpak Autonomous Socialist Soviet Republic was transferred to the Uzbek SSR.
What effect did the 1963 Soviet Constitution have on the size of the Russia?
A:
