premise: The FIL World Luge Championships 1957 took place in Davos, Switzerland. It marked the first time the event was held under the auspices of the International Luge Federation (FIL) which was formed earlier that year. Also, it was the first time the championships had been held after being cancelled the previous year.
hypothesis: The International Luge Federation was formed after 1956 and before 1959.
reason: It's correct because it says it was formed earlier that year, which is referring to 1957, and 1957 is after 1956 and before 1959. It's difficult because the statement has multiple comparisons in it to evaluate, which is difficult for the system.
