Here is a question about this article: Paper at this point is uncoated. Coated paper has a thin layer of material such as calcium carbonate or china clay applied to one or both sides in order to create a surface more suitable for high-resolution halftone screens. (Uncoated papers are rarely suitable for screens above 150 lpi.) Coated or uncoated papers may have their surfaces polished by calendering. Coated papers are divided into matte, semi-matte or silk, and gloss. Gloss papers give the highest optical density in the printed image.
What is the answer to this question: What is the shiniest type of coated paper?

So... Gloss

Here is a question about this article: Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design. He then published his observations in a series of letters to the Royal Society of London. Bacteria were Leeuwenhoek's most remarkable microscopic discovery. They were just at the limit of what his simple lenses could make out and, in one of the most striking hiatuses in the history of science, no one else would see them again for over a century. Only then were his by-then-largely-forgotten observations of bacteria as opposed to his famous "animalcules" (spermatozoa) taken seriously.
What is the answer to this question: How long did it take for his discovery to be taken seriously?
****
So... over a century

Here is a question about this article: During 182428 Chopin spent his vacations away from Warsaw, at a number of locales.[n 4] In 1824 and 1825, at Szafarnia, he was a guest of Dominik Dziewanowski, the father of a schoolmate. Here for the first time he encountered Polish rural folk music. His letters home from Szafarnia (to which he gave the title "The Szafarnia Courier"), written in a very modern and lively Polish, amused his family with their spoofing of the Warsaw newspapers and demonstrated the youngster's literary gift.
What is the answer to this question: To whom did Frederic write letters to during his stay in Szafarnia?

So...
his family
