Article: There are two basic forms of data packet, DATA0 and DATA1. A data packet must always be preceded by an address token, and is usually followed by a handshake token from the receiver back to the transmitter. The two packet types provide the 1-bit sequence number required by Stop-and-wait ARQ. If a USB host does not receive a response (such as an ACK) for data it has transmitted, it does not know if the data was received or not; the data might have been lost in transit, or it might have been received but the handshake response was lost.

Question: What is a data packet usually followed by?
Ans: a handshake token from the receiver back to the transmitter

Article: Often, through-hole and surface-mount construction must be combined in a single assembly because some required components are available only in surface-mount packages, while others are available only in through-hole packages. Another reason to use both methods is that through-hole mounting can provide needed strength for components likely to endure physical stress, while components that are expected to go untouched will take up less space using surface-mount techniques. For further comparison, see the SMT page.

Question: Surface-mount is one type of construction used in PCB assembly; what's the other one?
Ans: through-hole

Article: The women's division of professional wrestling has maintained a recognized world champion since 1937, when Mildred Burke won the original World Women's title. She then formed the World Women's Wrestling Association in the early 1950s and recognized herself as the first champion, although the championship would be vacated upon her retirement in 1956. The NWA, however, ceased to acknowledge Burke as their Women's World champion in 1954, and instead acknowledged June Byers as champion after a controversial finish to a high-profile match between Burke and Byers that year. Upon Byers' retirement in 1964, The Fabulous Moolah, who won a junior heavyweight version of the NWA World Women's Championship (the predecessor to the WWE's Women's Championship) in a tournament back in 1958, was recognized by most NWA promoters as champion by default.

Question: Who won the women's title in 1937?
Ans: Mildred Burke

Article: Until recently, in most critical writing the post-punk era was "often dismissed as an awkward period in which punk's gleeful ructions petered out into the vacuity of the Eighties". Contemporary scholars have argued to the contrary, asserting that the period produced significant innovations and music on its own. Simon Reynolds described the period as "a fair match for the sixties in terms of the sheer amount of great music created, the spirit of adventure and idealism that infused it, and the way that the music seemed inextricably connected to the political and social turbulence of its era". Nicholas Lezard wrote that the music of the period "was avant-garde, open to any musical possibilities that suggested themselves, united only in the sense that it was very often cerebral, concocted by brainy young men and women interested as much in disturbing the audience, or making them think, as in making a pop song".

Question: What did Nicholas Leonard say united post-punk?
Ans:
cerebral, concocted by brainy young men and women interested as much in disturbing the audience, or making them think, as in making a pop song
