Step-by-step explanation:
Which statement is TRUE regarding a country with a very large informal economy? Among the statements provided, the true statement is that the burden of taxes is spread less evenly among the population. This occurs because many individuals and businesses within the informal economy do not pay taxes, leading to a smaller tax base and hence, a more uneven distribution of tax burdens across the population.
Contrary to some beliefs, those working in the informal economy indeed contribute to national economic activity. They earn and spend money, albeit not formally recorded. Also, it is important to note that while the official GDP measure excludes informal economic activity, if it were included, the GDP measure would actually be larger. Therefore, the correct statement is that the informal economy can cause official GDP measures to be smaller than the true total economic activity. Lastly, there is no direct correlation suggesting that a very large informal economy is associated with less corruption and crime.
