[Critical Reasoning]

Crowding on Mooreville’s subway frequently leads to delays, because it is difficult for passengers to exit from the trains. Subway ridership is projected to increase by 20 percent over the next 10 years. The Mooreville Transit Authority plans to increase the number of daily train trips by only 5 percent over the same period. Officials predict that this increase is sufficient to ensure that the incidence of delays due to crowding does not increase.

Which of the following, if true, provides the strongest grounds for the officials’ prediction?

Which of the following most logically completes the argument?
Utrania was formerly a major petroleum exporter, but in recent decades economic stagnation and restrictive regulations inhibited investment in new oil fields.  In consequence, Utranian oil exports dropped steadily as old fields became depleted.  Utrania's currently improving economic situation, together with less-restrictive regulations, will undoubtedly result in the rapid development of new fields.  However, it would be premature to conclude that the rapid development of new fields will result in higher oil exports, because __________.

Archaeologists using a remote-controlled submarine to excavate an ancient shipwreck deep in the Mediterranean have been able to recover several objects from the site of the wreck.

However, the submarine has also recovered from the site some large olive oil jars that cannot be from before the eighth century A.D.
