Passage: Since then, tourism in Nepal has thrived; it is the country's most important industry.[citation needed] Tourism is a major source of income for most of the people in the city, with several hundred thousand visitors annually. Hindu and Buddhist pilgrims from all over the world visit Kathmandu's religious sites such as Pashupatinath, Swayambhunath, Boudhanath and Budhanilkantha. From a mere 6,179 tourists in 1961/62, the number jumped to 491,504 in 1999/2000. Following the end of the Maoist insurgency, there was a significant rise of 509,956 tourist arrivals in 2009. Since then, tourism has improved as the country turned into a Democratic Republic. In economic terms, the foreign exchange registered 3.8% of the GDP in 1995/96 but then started declining[why?]. The high level of tourism is attributed to the natural grandeur of the Himalayas and the rich cultural heritage of the country. Question: What event led to an increase in tourism in 2009?
end of the Maoist insurgency

Because of the overpopulation of dogs in some countries, many animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized. Question: In neutering, what is removed in female dogs?
ovaries and uterus
