Last year's Spring Festival, we only spent 2 days to sell 4 million yuan in welfare lottery tickets. This year's Spring Festival, we plan to sell 2,000 yuan in 10 days. It is not a problem. Which of the following best supports the above reasoning? ['In the Spring Festival, sports lottery sales event held the previous year, the lottery was sold for 10 million yuan in 5 days.', 'Sports lotteries have always been favored by lottery players because prizes are awarded in the form of bonuses.', "China's sports industry has developed rapidly, which is inseparable from the support of the people across the country. We also buy sports lottery to support sports.", 'In the process of selling sports lottery tickets every year, we find that the daily sales volume is similar.']
