Article: In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery ("PD") specification, an extension that specifies using certified "PD aware" USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5 W) to devices with larger power demand. Devices can request higher currents and supply voltages from compliant hosts –  up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 3 A or 5 A at either 12 V (36 W or 60 W) or 20 V (60 W or 100 W). In all cases, both host-to-device and device-to-host configurations are supported.

Question: What can devices request?
Ans: higher currents and supply voltages from compliant hosts


Here is a question about this article: Historically, the roots of Buddhism lie in the religious thought of ancient India during the second half of the first millennium BCE. That was a period of social and religious turmoil, as there was significant discontent with the sacrifices and rituals of Vedic Brahmanism.[note 15] It was challenged by numerous new ascetic religious and philosophical groups and teachings that broke with the Brahmanic tradition and rejected the authority of the Vedas and the Brahmans.[note 16] These groups, whose members were known as shramanas, were a continuation of a non-Vedic strand of Indian thought distinct from Indo-Aryan Brahmanism.[note 17] Scholars have reasons to believe that ideas such as samsara, karma (in the sense of the influence of morality on rebirth), and moksha originated in the shramanas, and were later adopted by Brahmin orthodoxy.[note 18][note 19][note 20][note 21][note 22][note 23]
What is the answer to this question: Scholars believe that karma originated in what?
****
So... the shramanas


The problem: Answer a question about this article:
Mac OS continued to evolve up to version 9.2.2, including retrofits such as the addition of a nanokernel and support for Multiprocessing Services 2.0 in Mac OS 8.6, though its dated architecture made replacement necessary. Initially developed in the Pascal programming language, it was substantially rewritten in C++ for System 7. From its beginnings on an 8 MHz machine with 128 KB of RAM, it had grown to support Apple's latest 1 GHz G4-equipped Macs. Since its architecture was laid down, features that were already common on Apple's competition, like preemptive multitasking and protected memory, had become feasible on the kind of hardware Apple manufactured. As such, Apple introduced Mac OS X, a fully overhauled Unix-based successor to Mac OS 9. OS X uses Darwin, XNU, and Mach as foundations, and is based on NeXTSTEP. It was released to the public in September 2000, as the Mac OS X Public Beta, featuring a revamped user interface called "Aqua". At US$29.99, it allowed adventurous Mac users to sample Apple's new operating system and provide feedback for the actual release. The initial version of Mac OS X, 10.0 "Cheetah", was released on March 24, 2001. Older Mac OS applications could still run under early Mac OS X versions, using an environment called "Classic". Subsequent releases of Mac OS X included 10.1 "Puma" (2001), 10.2 "Jaguar" (2002), 10.3 "Panther" (2003) and 10.4 "Tiger" (2005).
What language replaced Pascal for System 7?
****
The answer: C++

In the Battle of Cowan's Ford, Cornwallis met resistance along the banks of the Catawba River at Cowan's Ford on February 1, 1781, in an attempt to engage General Morgan's forces during a tactical withdrawal. Morgan had moved to the northern part of the state to combine with General Greene's newly recruited forces. Generals Greene and Cornwallis finally met at the Battle of Guilford Courthouse in present-day Greensboro on March 15, 1781. Although the British troops held the field at the end of the battle, their casualties at the hands of the numerically superior Continental Army were crippling. Following this "Pyrrhic victory", Cornwallis chose to move to the Virginia coastline to get reinforcements, and to allow the Royal Navy to protect his battered army. This decision would result in Cornwallis' eventual defeat at Yorktown, Virginia, later in 1781. The Patriots' victory there guaranteed American independence.

What did Cornwallis move to the coastline after losing the battle of Guilford Courthouse?
Answer: to get reinforcements


Anthropologists have contributed to the debate by shifting the focus of research: One of the first challenges for the researcher wishing to carry out empirical research in this area is to identify an appropriate analytical tool. The concept of boundaries is useful here for demonstrating how identity works. In the same way as Barth, in his approach to ethnicity, advocated the critical focus for investigation as being "the ethnic boundary that defines the group rather than the cultural stuff that it encloses" (1969:15), social anthropologists such as Cohen and Bray have shifted the focus of analytical study from identity to the boundaries that are used for purposes of identification. If identity is a kind of virtual site in which the dynamic processes and markers used for identification are made apparent, boundaries provide the framework on which this virtual site is built. They concentrated on how the idea of community belonging is differently constructed by individual members and how individuals within the group conceive ethnic boundaries.
What researcher advocated for focus on the boundaries of ethnic groups rather than the cultural aspects of ethnic groups?
Barth
