Input: Read this: The English term comics derives from the humorous (or "comic") work which predominated in early American newspaper comic strips; usage of the term has become standard for non-humorous works as well. The term "comic book" has a similarly confusing history: they are most often not humorous; nor are they regular books, but rather periodicals. It is common in English to refer to the comics of different cultures by the terms used in their original languages, such as manga for Japanese comics, or bandes dessinées for French-language Franco-Belgian comics.
Question: Comic is used for what other kind of work especially humorous works?

Output: unanswerable


Input: Read this: In 1906, the tungsten filament was introduced. Tungsten metal was initially not available in a form that allowed it to be drawn into fine wires. Filaments made from sintered tungsten powder were quite fragile. By 1910, a process was developed by William D. Coolidge at General Electric for production of a ductile form of tungsten. The process required pressing tungsten powder into bars, then several steps of sintering, swaging, and then wire drawing. It was found that very pure tungsten formed filaments that sagged in use, and that a very small "doping" treatment with potassium, silicon, and aluminium oxides at the level of a few hundred parts per million greatly improved the life and durability of the tungsten filaments.
Question: When was the ductile form of tungsten invented?

Output: 1910


Input: Read this: Initial reactions to the novel were varied. The New Yorker declared it "skilled, unpretentious, and totally ingenious", and The Atlantic Monthly's reviewer rated it as "pleasant, undemanding reading", but found the narrative voice—"a six-year-old girl with the prose style of a well-educated adult"—to be implausible. Time magazine's 1960 review of the book states that it "teaches the reader an astonishing number of useful truths about little girls and about Southern life" and calls Scout Finch "the most appealing child since Carson McCullers' Frankie got left behind at the wedding". The Chicago Sunday Tribune noted the even-handed approach to the narration of the novel's events, writing: "This is in no way a sociological novel. It underlines no cause ... To Kill a Mockingbird is a novel of strong contemporary national significance."
Question: What newspaper wrote that the novel has strong contemporary national significance?

Output:
The Chicago Sunday Tribune
