A. Krate Motors cannot increase its overall sales by increasing the sales of its cars in the geographical area allotted to Trump.
Negation: Krate Motors can increase its overall sales by increasing sales in the area allotted to Trump.
Effect on the argument: If Krate can boost overall sales in Trump’s area, then it may not be necessary to give Trump the exclusive contract for the entire country. Thus, this assumption is essential for the recommendation to hold true.
This is the assumption.
B. Comparison with Prax is not one of the main motivating factors for Trump to perform better on sales.
Negation: Comparison with Prax is a main motivating factor for Trump to perform better on sales.
Effect on the argument: The performance of Trump relative to Prax does not directly impact whether giving Trump an exclusive contract will increase overall sales. This assumption is not necessary for the argument.
Not the assumption.
C. Prax has not performed better than the dealerships of other companies in the geographical area allotted to it.
Negation: Prax has performed better than the dealerships of other companies in its area.
Effect on the argument: This assumption does not directly relate to whether giving Trump an exclusive contract will increase overall sales. The performance of Prax in comparison to others does not support or undermine the recommendation.
Not the assumption.
D. Trump will employ the same sales strategies in the newly allotted area as it does in the area originally allotted to it.
Negation: Trump will not employ the same sales strategies in the new area as it does in its original area.
Effect on the argument: While it might be beneficial for Trump to use the same strategies, this does not directly affect the assumption about whether overall sales will increase. The recommendation does not rely on the strategies being the same.
Not the assumption.
E. Trade surveys have shown that there is a large market for the kind of cars Krate Motors makes in the geographical area currently under Prax Motors.
Negation: Trade surveys have shown that there is not a large market for Krate Motors' cars in Prax’s area.
Effect on the argument: If there is not a large market in Prax's area, then giving Trump an exclusive contract might not boost overall sales, which would undermine the recommendation. Therefore, this is a crucial assumption because it addresses the demand in the area currently under Prax.
This is also an assumption.
Krate Motors cannot increase its overall sales by increasing the sales of its cars in the geographical area allotted to Trump.
This assumption is necessary because if Krate can increase sales in Trump’s area, there might be no need to give Trump an exclusive contract for the entire country.
However, E also plays a significant role in that it establishes the demand in Prax's area. But A is more directly tied to the recommendation about boosting overall sales by changing contracts.
Therefore, the best answer that aligns directly with the recommendation is A.
