PROBLEM: The Phantom of the Opera (French: Le Fantôme de l'Opéra) is a novel by French writer Gaston Leroux. It was first published as a serialization in Le Gaulois from 23 September 1909, to 8 January 1910. It was published in volume form in late March 1910 by Pierre Lafitte. The novel is partly inspired by historical events at the Paris Opera during the nineteenth century and an apocryphal tale concerning the use of a former ballet pupil's skeleton in Carl Maria von Weber's 1841 production of Der Freischütz. It has been successfully adapted into various stage and film adaptations, most notable of which are the 1925 film depiction featuring Lon Chaney, and Andrew Lloyd Webber's 1986 musical.

SOLUTION: what is the history of the phantom of the opera

PROBLEM: Thompson remains best known for Fear and Loathing in Las Vegas (1971), a book first serialized in Rolling Stone in which he grapples with the implications of what he considered the failure of the 1960s counterculture movement. It was adapted on film twice: loosely in Where the Buffalo Roam starring Bill Murray as Thompson in 1980, and directly in 1998 by director Terry Gilliam in film starring Johnny Depp and Benicio del Toro. The Doonesbury cartoon character Duke -- who was modeled after Thompson -- pens an essay about 'my shoplifting conviction' entitled 'Fear and Loathing at Macy's Menswear', an obvious reference to Thompson's book.

SOLUTION: who wrote fear and loathing in las vegas

PROBLEM: Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. The most familiar, and historically the oldest, types of glass are 'silicate glasses' based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO), sodium oxide (Na O) from sodium carbonate (Na CO), calcium oxide (CaO), also called lime, and several minor additives.

SOLUTION:
name two articles that can be made from glass
