Since last year, real estate prices in many major cities across the country, including Guangzhou, have increased in varying degrees, and some cities have even reached recent highs. This is also a rise in real estate prices since the country introduced a series of regulatory measures last year. In this context, some people have argued that the macro-control measures introduced by the state last year did not achieve the expected results. Which of the following can best refute the above conclusions? [' the country does not introduce a series of macro-control measures, real estate prices may rise even higher.', 'The impact of the regulatory measures introduced by country B last year on housing prices requires a process, and it is impossible to achieve immediate results.', 'ccording to the recent survey of real estate supply and demand by relevant departments, how much real estate supply has fallen in the first half of this year.', 'ntry D is already open to real estate prices. Since real estate prices are mainly affected by market supply and demand, it is impossible for macroeconomic regulation to introduce nationally prescribed prices.']
