The argument's core idea is that verdicts against corporations should be proportionally as large (relative to revenue) as verdicts against individuals (relative to income). This implicitly assumes that the ability to pay should be a factor in determining the size of the award.
Let's look at why the correct answer is (B): (B) The extent to which the payment is expensive to the defendant should be a consideration in the determination of awards. This is precisely the assumption the argument makes. It argues for proportional verdicts based on the defendant's financial capacity (revenue for corporations, income for individuals). The argument hinges on the idea that the "expense" of the payment relative to the defendant's resources is a key factor.
Why the other options are incorrect: (A) Insurance companies often fail to pay the sums dictated in verdicts reached against individual defendants.
This is irrelevant to the core argument about proportional verdicts. Whether insurance pays or not doesn't affect the argument about the size of the verdict relative to the defendant's finances.
(C) Corporations are responsible for at least as many of the problems in our society as are individuals.
This discusses the relative culpability of corporations and individuals, which is not the central point of the argument. The argument focuses on the size of the award, not the reason for it.
(D) No punishment is too large for the truly guilty.
This is a general statement about punishment and guilt, not specifically about proportional verdicts tied to financial capacity. The argument doesn't address the concept of "guilt" directly.
(E) The justice system has always been effective in collecting large sums imposed on defendants.
The effectiveness of collecting the money is separate from the argument about how the amount is determined. The argument concerns the principle of proportional verdicts, not the practicality of enforcement.
Therefore, the correct answer is (B).
