QUES: In general, USB cables have only plugs on their ends, while hosts and devices have only receptacles. Hosts almost universally have Type-A receptacles, while devices have one or another Type-B variety. Type-A plugs mate only with Type-A receptacles, and the same applies to their Type-B counterparts; they are deliberately physically incompatible. However, an extension to the USB standard specification called USB On-The-Go (OTG) allows a single port to act as either a host or a device, which is selectable by the end of the cable that plugs into the receptacle on the OTG-enabled unit. Even after the cable is hooked up and the units are communicating, the two units may "swap" ends under program control. This capability is meant for units such as PDAs in which the USB link might connect to a PC's host port as a device in one instance, yet connect as a host itself to a keyboard and mouse device in another instance.

Hosts almost always have what type of receptacle?
What is the answer?
ANS: Type-A receptacles
QUES: Several dozen radioisotopes have been characterized. 65Zn, which has a half-life of 243.66 days, is the most long-lived radioisotope, followed by 72Zn with a half-life of 46.5 hours. Zinc has 10 nuclear isomers. 69mZn has the longest half-life, 13.76 h. The superscript m indicates a metastable isotope. The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray. 61Zn has three excited states and 73Zn has two. The isotopes 65Zn, 71Zn, 77Zn and 78Zn each have only one excited state.

How many boring states does 61Zn have?
What is the answer?
ANS: unanswerable
QUES: Christoph Waltz was cast in the role of Franz Oberhauser, though he refused to comment on the nature of the part. It was later revealed with the film's release that he is Ernst Stavro Blofeld. Dave Bautista was cast as Mr. Hinx after producers sought an actor with a background in contact sports. After casting Bérénice Lim Marlohe, a relative newcomer, as Sévérine in Skyfall, Mendes consciously sought out a more experienced actor for the role of Madeleine Swann, ultimately casting Léa Seydoux in the role. Monica Bellucci joined the cast as Lucia Sciarra, becoming, at the age of fifty, the oldest actress to be cast as a Bond girl. In a separate interview with Danish website Euroman, Jesper Christensen revealed he would be reprising his role as Mr. White from Casino Royale and Quantum of Solace. Christensen's character was reportedly killed off in a scene intended to be used as an epilogue to Quantum of Solace, before it was removed from the final cut of the film, enabling his return in Spectre.

Who did Christoph Waltz portray in Spectre?
