Question ID:PT47 S3 Q7 Passage:Legislator:  To keep our food safe, we must prohibit the use of any food additives that have been found to cause cancer.Commentator:  An absolute prohibition is excessive. Today's tests can detect a single molecule of potentially cancer-causing substances, but we know that consuming significantly larger amounts of such a chemical does not increase one's risk of getting cancer. Thus, we should instead set a maximum acceptable level for each problematic chemical, somewhat below the level at which the substance has been shown to lead to cancer but above zero. Stem:Of the following, which one, if true, is the logically strongest counter the legislator can make to the commentator's argument? Correct Answer Choice:BChoice A:The level at which a given food additive has been shown to lead to cancer in children is generally about half the level at which it leads to cancer in adults. Choice B:Consuming small amounts of several different cancer-causing chemicals can lead to cancer even if consuming such an amount of any one cancer-causing chemical would not. Choice C:The law would prohibit only the deliberate addition of cancer-causing chemicals and would not require the removal of naturally occurring cancer-causing substances. Choice D:For some food additives, the level at which the substance has been shown to lead to cancer is lower than the level at which the additive provides any benefit. Choice E:All food additives have substitutes that can be used in their place.
