Quote:
Among firms that transport their goods via truck, some hire drivers directly, whereas others contract transportation to outside firms. Firms that transport food items are twice as likely as other firms to hire drivers directly. Firms that transport perishable food items , which must be delivered in a timely manner, are more than five times more likely than other firms to hire drivers directly, while firms that transport non-perishable food items are only slightly more likely than other firms to do so.
The information above provides the most support for which of the following hypotheses?
(A) A firm's decision to hire drivers directly depends in part on whether goods must be delivered in a timely manner.
(B) It is usually more expensive to hire drivers directly than to contract transportation to outside firms.
(C) Firms that hire drivers directly are unlikely to do business with firms that contract transportation to outside firms.
(D) Firms that provide truck transportation usually carry non-food items.
(E) Between one-fifth and one-half of firms that transport their goods via truck contract transportation to outside firms.
Premise: Among firms that transport their goods via truck, some hire drivers directly while others contract transportation out to external firms.
Premise: Firms that transport food items are twice as likely to hire drivers directly.
Premise: Firms that transport perishable food items, which must be delivered in a timely manner, are more than five times more likely to hire drivers directly.
Premise: Firms that transport non-perishable food items are only slightly more likely to hire drivers directly.
A. This is an inference that could be made, because firms that transport perishable food items are significantly more likely to hire drivers directly when compared to firms that transport non-perishable food items.
B. Cost isn’t discussed here, so it’s irrelevant.
C. This isn’t supported by any part of the passage.
D. This isn’t supported either. We’re mostly talking about food transportation, but no percentages are given.
E. We don’t know what percentage of firms that transport goods via truck are transporting food items, so we can’t make any inferences about the overall fraction that contract transportation to outside firms.
Best answer is A.
