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.
In all cases, both host-to-device and device-to-host configurations are what?
A: supported

The climate of Antarctica does not allow extensive vegetation to form. A combination of freezing temperatures, poor soil quality, lack of moisture, and lack of sunlight inhibit plant growth. As a result, the diversity of plant life is very low and limited in distribution. The flora of the continent largely consists of bryophytes. There are about 100 species of mosses and 25 species of liverworts, but only three species of flowering plants, all of which are found in the Antarctic Peninsula: Deschampsia antarctica (Antarctic hair grass), Colobanthus quitensis (Antarctic pearlwort) and the non-native Poa annua (annual bluegrass). Growth is restricted to a few weeks in the summer.
What does the climate of Antarctica inhibit?
A: plant growth

The final is normally held the Saturday after the Premier League season finishes in May. The only seasons in recent times when this pattern was not followed were 19992000, when most rounds were played a few weeks earlier than normal as an experiment, and 201011 and 201213 when the FA Cup Final was played before the Premier League season had finished, to allow Wembley Stadium to be ready for the UEFA Champions League final, as well as in 201112 to allow England time to prepare for that summer's European Championships.
Did that ever happen again?
A: 201011 and 201213

While pursuing his PhD at Princeton, Feynman married his high school sweetheart, Arline Greenbaum (often misspelled "Arlene"), despite the knowledge that she was seriously ill with tuberculosisan incurable disease at the time. She died in 1945. In 1946, Feynman wrote a letter to her, expressing his deep love and heartbreak, that he kept for the rest of his life. ("Please excuse my not mailing this," the letter concluded, "but I don't know your new address.") This portion of Feynman's life was portrayed in the 1996 film Infinity, which featured Feynman's daughter, Michelle, in a cameo role.
What was the name of the film that showed Feynman's life?
