Unless tiger hunting decreases, tigers will soon be extinct in the wild. The countries in which the tigers' habitats are located are currently debating joint legislation that would ban tiger hunting. Thus, if these countries can successfully enforce this legislation, the survival of tigers in the wild will be ensured.

The reasoning in the argument is most vulnerable to criticism on the grounds that the argument

• Aassumes without sufficient warrant that a ban on tiger hunting could be successfully enforced  
• Bconsiders the effects of hunting on tigers without also considering the effects of hunting on other endangered animal species  
• Cfails to take into account how often tiger hunters are unsuccessful in their attempts to kill tigers  
• Dneglects to consider the results of governmental attempts in the past to limit tiger hunting  
• Etakes the removal of an impediment to the tigers' survival as a guarantee of their survival
