Economist: Real wages in this country will increase significantly only if productivity increases notably. Thus, it is unlikely that real wages will increase significantly in the near future, since this country' s businesses are currently investing very little in new technology and this pattern is likely to continue for at least several more years. Which one of the following, if assumed about the economist's country, allows the economist's conclusion to be properly drawn? ['Productivity will not increase if businesses do not make a substantial investment in new technology.', 'The new technology in which businesses are currently investing is not contributing to an increase in productivity.', 'Neither real wages nor productivity have increased in the last several years.', 'Sooner or later real wages will increase significantly.']
