Problem: Nintendo Entertainment System:

When Nintendo released the NES in the US, the design styling was deliberately different from that of other game consoles. Nintendo wanted to distinguish its product from those of competitors and to avoid the generally poor reputation that game consoles had acquired following the video game crash of 1983. One result of this philosophy was to disguise the cartridge slot design as a front-loading zero insertion force (ZIF) cartridge socket, designed to resemble the front-loading mechanism of a VCR. The newly designed connector worked quite well when both the connector and the cartridges were clean and the pins on the connector were new. Unfortunately, the ZIF connector was not truly zero insertion force. When a user inserted the cartridge into the NES, the force of pressing the cartridge down and into place bent the contact pins slightly, as well as pressing the cartridge’s ROM board back into the cartridge itself. Frequent insertion and removal of cartridges caused the pins to wear out from repeated usage over the years and the ZIF design proved more prone to interference by dirt and dust than an industry-standard card edge connector. These design issues were not alleviated by Nintendo’s choice of materials; the console slot nickel connector springs would wear due to design and the game cartridge copper connectors were also prone to tarnishing. Many players would try to alleviate issues in the game caused by this corrosion by blowing into the cartridges, then reinserting them, which actually hurt the copper connectors by speeding up the tarnishing.

 What material weren't the early connector springs made of?

Problem: Multiracial American:

Sometimes people of mixed African-American and Native American descent report having had elder family members withholding pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, as censuses did not identify slaves by name before the American Civil War, meaning that most African Americans did not appear by name in those records. In addition, many white fathers who used slave women sexually, even those in long-term relationships like Thomas Jefferson's with Sally Hemings, did not acknowledge their mixed-race slave children in records, so paternity was lost.

Who acknowledged their mixed-race slave children in records?

A: unanswerable


Problem: Kanye West:

West's fourth studio album, 808s & Heartbreak (2008), marked an even more radical departure from his previous releases, largely abandoning rap and hip hop stylings in favor of a stark electropop sound composed of virtual synthesis, the Roland TR-808 drum machine, and explicitly auto-tuned vocal tracks. Drawing inspiration from artists such as Gary Numan, TJ Swan and Boy George, and maintaining a "minimal but functional" approach towards the album's studio production, West explored the electronic feel produced by Auto-Tune and utilized the sounds created by the 808, manipulating its pitch to produce a distorted, electronic sound; he then sought to juxtapose mechanical sounds with the traditional sounds of taiko drums and choir monks. The album's music features austere production and elements such as dense drums, lengthy strings, droning synthesizers, and somber piano, and drew comparisons to the work of 1980s post-punk and new wave groups, with West himself later confessing an affinity with British post-punk group Joy Division. Rolling Stone journalist Matthew Trammell asserted that the record was ahead of its time and wrote in a 2012 article, "Now that popular music has finally caught up to it, 808s & Heartbreak has revealed itself to be Kanye’s most vulnerable work, and perhaps his most brilliant."

The article about Kanye's fourth album written by Matthew Trammell was published in what magazine?

Problem: Neolithic:

The Neolithic 2 (PPNB) began around 8,800 BCE according to the ASPRO chronology in the Levant (Jericho, Israel). As with the PPNA dates, there are two versions from the same laboratories noted above. This system of terminology, however, is not convenient for southeast Anatolia and settlements of the middle Anatolia basin. This era was before the Mesolithic era.[citation needed] A settlement of 3,000 inhabitants was found in the outskirts of Amman, Jordan. Considered to be one of the largest prehistoric settlements in the Near East, called 'Ain Ghazal, it was continuously inhabited from approximately 7,250 – 5,000 B.

What era preceded the Neolithic 2 (PPNB) era?
