The businessman targets the trucker's assumption and suggests that the transportation industry will not shrink, just experience a shift from trucks to other means of transportation.
While the businessman disputes the trucker's underlying assumption, he does not support the trucker's conclusion. On the contrary - it can be inferred that the businessman believes the trucker's conclusion is incorrect and that the industry will not shrink.C. challenging the validity of the evidence the trucker cites as the basis for the conclusion
Incorrect.
The businessman does not challenge the validity of the evidence the trucker cites. He agrees that the new law caused trucker to lose money and that this eventually caused them to lose clients. The difference between the businessman and the trucker is the conclusions at which they arrive based on the same evidence. D. reinforcing the trucker's conclusion by complementing the picture with further evidence
Incorrect.
The businessman is indeed somewhat supportive of the trucker's plight, by implying that the truckers will lose business. If the trucker's conclusion had been that the new law will cause the trucking business to collapse, D would indeed have been the right answer. However, the trucker's conclusion goes too far in claiming that the entire transport industry will be hurt - a conclusion that is challenged by the businessman's point that some parts of the transportation business might actually benefit from the new law, namely the small commercial vehicle, trains and boats.
This is the reason it is important to first analyze the arguments presented and correctly identify and record the premises and conclusion. Focus on the argument as presented, not on the argument going on in your mind.E. implying that the trucker's conclusion is based on false premises
Incorrect.
The businessman does not challenge the validity of the premises the trucker cites. He agrees that the new law caused trucker to lose money and that this eventually caused them to lose clients. The difference between the businessman and the trucker is the conclusions at which they arrive based on the same premises.
