Problem: Nintendo Entertainment System:

A variety of games for the FDS were released by Nintendo (including some like Super Mario Bros. which had already been released on cartridge) and third party companies such as Konami and Taito. A few unlicensed titles were made as well. However, its limitations became quickly apparent as larger ROM chips were introduced, allowing cartridges with greater than 128k of space. More advanced memory management chips (MMC) soon appeared and the FDS quickly became obsolete. Nintendo also charged developers considerable amounts of money to produce FDS games, and many refused to develop for it, instead continuing to make cartridge titles. Many FDS disks have no dust covers (except in some unlicensed and bootleg variants) and are easily prone to getting dirt on the media. In addition, the drive use a belt which breaks frequently and requires invasive replacement. After only two years, the FDS was discontinued, although vending booths remained in place until 1993 and Nintendo continued to service drives, and to rewrite and offer replacement disks until 2003.

How long did Atari service drives and offer replacement disks?

Context and question: Cities not served by road, sea, or river can be reached only by air, foot, dogsled, or snowmachine, accounting for Alaska's extremely well developed bush air servicesan Alaskan novelty. Anchorage and, to a lesser extent Fairbanks, is served by many major airlines. Because of limited highway access, air travel remains the most efficient form of transportation in and out of the state. Anchorage recently completed extensive remodeling and construction at Ted Stevens Anchorage International Airport to help accommodate the upsurge in tourism (in 2012-2013, Alaska received almost 2 million visitors).
Which two cities are unserved by major airlines?
Answer: unanswerable

Question: Gag and editorial cartoons usually consist of a single panel, often incorporating a caption or speech balloon. Definitions of comics which emphasize sequence usually exclude gag, editorial, and other single-panel cartoons; they can be included in definitions that emphasize the combination of word and image. Gag cartoons first began to proliferate in broadsheets published in Europe in the 18th and 19th centuries, and the term "cartoon"[h] was first used to describe them in 1843 in the British humour magazine Punch.
Is there an answer to this question: When did gag single-panel illustrations become known as cartoons?

Question: Critical appraisal of the film was mixed in the United States. In a lukewarm review for RogerEbert.com, Matt Zoller Seitz gave the film 2.5 stars out of 4, describing Spectre as inconsistent and unable to capitalise on its potential. Kenneth Turan, reviewing the film for Los Angeles Times, concluded that Spectre "comes off as exhausted and uninspired". Manohla Dargis of The New York Times panned the film as having "nothing surprising" and sacrificing its originality for the sake of box office returns. Forbes' Scott Mendelson also heavily criticised the film, denouncing Spectre as "the worst 007 movie in 30 years". Darren Franich of Entertainment Weekly viewed Spectre as "an overreaction to our current blockbuster moment", aspiring "to be a serialized sequel" and proving "itself as a Saga". While noting that "[n]othing that happens in Spectre holds up to even minor logical scrutiny", he had "come not to bury Spectre, but to weirdly praise it. Because the final act of the movie is so strange, so willfully obtuse, that it deserves extra attention." In a positive review Rolling Stone, Peter Travers gave the film 3.5 stars out of 4, describing "The 24th movie about the British MI6 agent with a license to kill is party time for Bond fans, a fierce, funny, gorgeously produced valentine to the longest-running franchise in movies". Other positive reviews from Mick LaSalle from the San Francisco Chronicle, gave it a perfect 100 score, stating: "One of the great satisfactions of Spectre is that, in addition to all the stirring action, and all the timely references to a secret organization out to steal everyone's personal information, we get to believe in Bond as a person." Stephen Whitty from the New York Daily News, gave it an 80 grade, saying: "Craig is cruelly efficient. Dave Bautista makes a good, Oddjob-like assassin. And while Lea Seydoux doesn't leave a huge impression as this film's "Bond girl," perhaps it's because we've already met far too briefly the hypnotic Monica Bellucci, as the first real "Bond woman" since Diana Rigg." Richard Roeper from the Chicago Sun-Times, gave it a 75 grade. He stated: "This is the 24th Bond film and it ranks solidly in the middle of the all-time rankings, which means it's still a slick, beautifully photographed, action-packed, international thriller with a number of wonderfully, ludicrously entertaining set pieces, a sprinkling of dry wit, myriad gorgeous women and a classic psycho-villain who is clearly out of his mind but seems to like it that way." Michael Phillips over at the Chicago Tribune, gave it a 75 grade. He stated: "For all its workmanlike devotion to out-of-control helicopters, "Spectre" works best when everyone's on the ground, doing his or her job, driving expensive fast cars heedlessly, detonating the occasional wisecrack, enjoying themselves and their beautiful clothes." Guy Lodge from Variety, gave it a 70 score, stating: "What's missing is the unexpected emotional urgency of "Skyfall," as the film sustains its predecessor's nostalgia kick with a less sentimental bent."
