Question: 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.
Is there an answer to this question: When were large hotels built in the Alps? 

Answer: during the Belle Époque


Question: Another non-obligate symbiosis is known from encrusting bryozoans and hermit crabs that live in a close relationship.

Is there an answer to this question: What species of crab has a helicospiral-tubular extension of its living chamber?

Answer: unanswerable
