Understanding the argument -
During the past year, Pro-Tect Insurance Company's total payout on car-theft claims has been larger than the company can afford to sustain. - Problem
Pro-Tect cannot reduce the number of car-theft policies it carries, so it cannot protect itself against continued large payouts that way. - Also explaining the problem of choosing a normal solution, which is to reduce the number of car theft policies it carries and opening doors for choosing an alternate solution (providing discounts)
Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices. - Pre-Tect's alternative solution or response to the problem. It is important to note that this is not the main conclusion as it says "has decided." This is something that was decided in the past, and the effect still continues, as shown by the present perfect.
Many policyholders will respond to the discount by installing such devices, since the amount of the discount will within two years typically more than cover the cost of installation. Response to the alternative solution.
Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts. - The main conclusion is that the plan is likely to reduce the annual cost. "is likely" explains the futuristic aspect of the steps we have taken.
We can use the therefore test here -
Say
Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices, SO Pro-Tect's plan is likely to reduce its annual payouts or
Pro-Tect's plan (plan of antitheft devices) is likely to reduce its annual payouts, SO Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.
The first one makes sense because the first introduces what the plan is - the plan is to offer a discount to holders of car-theft policies whose cars have antitheft devices, then assesses why the plan will succeed (as the discount covers the cost) and as a result of that plan and surely of a positive response from the customers, Pro-Tect is likely to reduce its annual payouts.
The 2nd one doesn't make sense. We don't know what the plan is, and we don't know if that plan will succeed, but somehow, we say the plan is likely (futuristic) to reduce cost, so let's implement the plan (that, by the way, has been implemented).
Understanding the main conclusion is important as it'll help to eliminate some options.
In the argument above, the two portions in boldface play which of the following roles?
(A) The first and the second are both evidence offered by the argument as support for its main conclusion. - No. The second is the main conclusion.
(B) The first presents a problem a response to which the argument assesses (the word assess is a bit confusing as typically asses means finding +ves and -ves and then opinion. The only way I can explain it is that the first boldface highlights the problem with choosing the normal solution to solve the problem mentioned in statement 1, which is that the total payout on car theft claims has been larger than the company can afford to sustain. So, as a response to this problem, the argument shares an alternative solution, which is offering discounts....and then the argument further checks the possible response to an alternate solution that the users will respond positively. Why? Because the discount covers the cost in 2 years. A lot to unpack here); the second is the judgment reached by that assessment. (Ok)
(C) The first is the position the argument seeks to establish; (the first is not the main conclusion) the second is a judgment the argument uses to support that position. (The 2nd BF is not supporting BF1)
(D) The first is a development that the argument seeks to explain (the first is not a development but a problem with the normal solution); the second is a prediction the argument makes in support of the explanation it offers. (The BF2 does not support the explanation. It is a result of the alternative solution.)
(E) The first presents a development whose likely outcome is at issue in the argument (first, the BF1 is not a development. It highlights the problem with the normal solution. The outcome of the acknowledgment that the problem of normal solution will not solve the main problem (statement 1) is the alternative solution. The alternative solution is not the issue in the argument); the second is a judgment the argument uses in support of its conclusion about that outcome. (the 2nd is the conclusion of the outcome and not the support.)
