For food security, a country has lowered its grain export tax rebate rate four times in the past year to curb food exports. However, the country's food exports are still increasing and it is highly competitive in international shopping malls. If the above is true, the best support for this situation is:. ['Food is in short supply on the international market.', "The quality of the country's food enjoys a high reputation in the international market.", 'Food prices in the country remain lower than in other countries after lowering tax rebates.', 'Food production in the country is still increasing.']
