Input: Read this: The development of flattop vessels produced the first large fleet ships. In 1918, HMS Argus became the world's first carrier capable of launching and recovering naval aircraft. As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships. These conversions gave rise to the Lexington-class aircraft carriers (1927), Akagi and Courageous class. Specialist carrier evolution was well underway, with several navies ordering and building warships that were purposefully designed to function as aircraft carriers by the mid-1920s, resulting in the commissioning of ships such as Hōshō (1922), HMS Hermes (1924), and Béarn (1927). During World War II, these ships would become known as fleet carriers.[citation needed]
Question: What was the world's first carrier capable of launching and recovering naval aircraft?

Output: HMS Argus

QUES: The tourism industry began in the early 19th century when foreigners visited the Alps, traveled to the bases of the mountains to enjoy the scenery, and stayed at the spa-resorts. Large hotels were built during the Belle Époque; cog-railways, built early in the 20th century, brought tourists to ever higher elevations, with the Jungfraubahn terminating at the Jungfraujoch, well above the eternal snow-line, after going through a tunnel in Eiger. During this period winter sports were slowly introduced: in 1882 the first figure skating championship was held in St. Moritz, and downhill skiing became a popular sport with English visitors early in the 20th century, as the first ski-lift was installed in 1908 above Grindelwald.
When did the tourism industry begin? 

ANS: the early 19th century


Studies conducted on both animals and humans show major bidirectional relationships between the circadian system and abusive drugs. It is indicated that these abusive drugs affect the central circadian pacemaker. Individuals suffering from substance abuse display disrupted rhythms. These disrupted rhythms can increase the risk for substance abuse and relapse. It is possible that genetic and/or environmental disturbances to the normal sleep and wake cycle can increase the susceptibility to addiction.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can the disrupted circadian system cause?
Ah, so.. abuse and relapse


Question: In contrast with other Romance languages, Catalan has many monosyllabic words; and those ending in a wide variety of consonants and some consonant clusters. Also, Catalan has final obstruent devoicing, thus featuring many couplets like amic "(male friend") vs. amiga ("female friend").
Try to answer this question if possible: How is Catalan different from other Romance languages?

Problem: Genre fiction also showed it could question reality in its 20th century forms, in spite of its fixed formulas, through the enquiries of the skeptical detective and the alternative realities of science fiction. The separation of "mainstream" and "genre" forms (including journalism) continued to blur during the period up to our own times. William Burroughs, in his early works, and Hunter S. Thompson expanded documentary reporting into strong subjective statements after the second World War, and post-modern critics have disparaged the idea of objective realism in general.
What idea have modern critics disparaged?
