Stimulus

The fishing industry cannot currently be relied upon to help the government count the seabirds killed by net fishing, since an accurate count might result in restriction of net fishing. The government should therefore institute a program under which tissue samples from the dead birds are examined to determine the amount of the industry needs to know whether the fish it catches are contaminated with toxins.

Which one of the following, if true, most strongly indicates that the government program would not by itself provide an accurate count of the

Answer choices

  1. No Impact17% picked this

    The seabirds killed by net fishing might be contaminated with several different toxins even if the birds eat

    We don't care whether it's one type of toxin or a variety of toxins in seabirds. We just want to know if the government will get an accurate count of how many seabirds are killed from fishing. This answer doesn't have any clear impact on the plan.

  2. Correct60% picked this

    The fishing industry could learn whether the fish it catches are contaminated with toxins if only a few of the seabirds killed

    Why this is right

    This is similar to the objection we raised above. This indicates that only a small sample of seabirds might suffice for the fishing industry to gain the information it needs about toxins. Thus, they wouldn't need to turn in all the bird carcasses, and an accurate total count wouldn't necessarily be achieved.

    Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

  3. No Impact3% picked this

    The government could gain valuable information about the source of toxins by examining tissue samples of the seabirds

    We're focused on the stated Goal of getting an accurate count of the number of dead seabirds. If the Plan also leads to other benefits, cool, but that has nothing to do with our current task. Learning about sources of toxins doesn't address whether the industry will report all carcasses or just a few, affecting the count's accuracy.

  4. No Impact11% picked this

    The fish caught in a particular net might be contaminated with the same toxins as those in the

    The Plan is probably assuming that in many cases the birds and the fish will have the same toxins. After all, the fish all swim in the same area and the birds are eating those fish. So this seems to state a weak idea our common sense would already know. It definitely doesn't give us any way to argue that this Plan will not result in an accurate count of dead seabirds.

  5. Opposite (if Anything)8% picked this

    The government would be willing to certify that the fish caught by the industry are not contaminated with toxins if tests done

    The government's willingness to certify non-contaminated fish based on tests would offer a further incentive for the fishing industry to cooperate, increasing the chances that the Plan would achieve its Goal.
