The line of reasoning (LoR) of the original argument: Evidence: parent-leave law will harm economic competitiveness. Conclusion: Companies must be freed of the burden of this law. A is not relevant, because A, parent-leave law serves to strengthen family, has nothing to do with the LoR of the argument. Whether family is strengthened or not is outside the scope of this argument. C is the best answer, because C provides an example which directly contradicts the original evidence. Please note in this type of weakening question, we don’t need to seek a perfect choice that will completely destroy the original argument. We only need to find from all the given choices the comparatively best one, which can cast severe doubt on the original argument -- this is enough. |
