Senator Strongwood reported that, contrary to a study cited by the administration, a thorough study by his own party concluded that a reduction in the capital gains tax would lead to an increase in the federal deficit. "Hooray for common sense, " he said. "Everyone knows that when you cut taxes you lose revenue. " He concluded that the administration' s plan for reducing the capital gains tax was now dead, because he could not imagine any senator voting to increase the deficit. Which one of the following accurately describes something Senator Strongwood does in advancing his argument? ['He resorts to name-calling by expressly stating that his opponents lack common sense.', 'He assumes that senators will rarely vote for unpopular legislation.', 'He assumes that a study commissioned by his party must be more objective than one commissioned by the administration.', "He assumes senators will believe his party's report instead of the administration's."]
