Bit of a weirdly worded question that is missing articles such as "the".
The argument is that the CAT is not expected to significantly bring down the rates of auto accidents in the long run.
This is based on the evidence of a recent study conducted by HDLI that found volvo xc60 drivers, a model equipped with the CAT, reported 27% fewer insurance claims than did drivers of comparable vehicles.
We need to evaluate the argument. The conditions of our answer must include a situation where the CAT exists in order for the effect to actually be a reality.
A weakens the argument actually. If the XC60 drivers make the highest # claims then other drivers make the lowest number of claims, so their claims would also be reduced and potentially this reduction would make more of a percentage change difference to overall claims.
B - doesn't allow for a situation in which the CAT exists. If the CAT won't exist it obviously wont have its intended effect. The situation we want is one in which the CAT exists but it may not have its intended effect.
C - this is spot on. It allows both premise and conclusion to exist. Substitute C into the question:
Many drivers will see the enhanced safety of the car as a reason to drive more recklessly; therefore, the CAT is not expected to significantly bring down the rates of auto accidents in the long run.
D - The argument isn't concerned with other technologies, it's concerned with CAT.
E - doesn't matter. Maybe HDLI was extremely efficient? Maybe they received the responses they needed in a shorter period of time than was previously budgeted? Heaps of reasons why this AC is incorrect.
