Good work guys! OA is D.
OE:
Step 1: ID Question Type and Task
A question that contains an apparent contradiction indicates a Paradox Question.
Task: Find the seemingly contradictory issue.
Step 2: Read the Argument and Extract Necessary Information:
The necessary information is the paradox, identify the paradox and pose it to yourself as a question.
Paradox: Why did the expected increase in sales not occur based on the benefits of the cars and the reason for those benefits?
Step 3: Formulate an Answer to the Question
Formulate a resolution to the paradox (if possible).
Remember, the best answer provides a connection between the two sides of the paradox without changing or discounting either side.
Step 4: Eliminate Answer Choices:
(A) Eliminate. This exacerbates the paradox in that it makes the cars that much more appealing.
(B) Eliminate. This only addresses the side of the issue that sales are down, it doesn`s like it to the reasons stated for the expected increase in sales.
(C) Eliminate. This exacerbates the paradox by making the cars more appealing.
(D) Keep. This could explain why the expected sales did not occur because of people`s disposition toward robot-produced products.
(E) Eliminate. This is irrelevant to the argument.
Step 5: Identify differences in remaining choices
(D) is the only remaining answer choice and is the correct answer.
