Since its establishment in 1974, the Hong Kong Independent Commission Against Corruption has vigorously combated corruption, investigating more than 2,200 corruption and bribery cases, and prosecuted 1,355 government officials involved in crimes. In Hong Kong, there are so many investigations and so many people involved. However, it has not hindered Hong Kong's economic development and prosperity. This sentence supports an argument, namely:. ['The anti-corruption struggle will affect economic construction.', 'The fight against corruption itself will not affect economic construction.', 'Corruption in Hong Kong is very serious.', "Hong Kong's economic development and prosperity are largely due to its clean and efficient civil service."]
