Context and question: 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.
What can devices request?
Answer: higher currents and supply voltages from compliant hosts
Context and question: The Black Wednesday economic disaster in September 1992 left the Conservative government's reputation for monetary excellence in tatters, and by the end of that year Labour had a comfortable lead over the Tories in the opinion polls. Although the recession was declared over in April 1993 and a period of strong and sustained economic growth followed, coupled with a relatively swift fall in unemployment, the Labour lead in the opinion polls remained strong. However, Smith died from a heart attack in May 1994.
What did Smith die of?
Answer: a heart attack
Context and question: Breeding usually involves some form of courtship display, typically performed by the male. Most displays are rather simple and involve some type of song. Some displays, however, are quite elaborate. Depending on the species, these may include wing or tail drumming, dancing, aerial flights, or communal lekking. Females are generally the ones that drive partner selection, although in the polyandrous phalaropes, this is reversed: plainer males choose brightly coloured females. Courtship feeding, billing and allopreening are commonly performed between partners, generally after the birds have paired and mated.
Generally, when is courtship feeding and billing performed between partners?
Answer:
after the birds have paired and mated
