The Fieldpark nuclear power plant, cited three years ago by a governmentally led safety commission for exceeding safe levels of radiation, has recently allowed the media access to its facilities. A spokesperson for the plant has claimed that the media has full access to the plant and is not prohibited from taking pictures on the premises. The spokesperson promises that, as a result, the citizens of Fieldpark can rest assured that, until next year's governmental inspection, the facility will not exceed the federal regulations on the amount of sieverts, or radiation, to which a person can be exposed.

Which of the following is an assumption upon which the spokesperson's conclusion depends?

A:The media will publish all of the photos it deems incriminating.

B:The number of sieverts the plant releases has not increased since the last governmental inspection.

C:Communities are located close enough to the power plant to be harmed should the plant release more radiation than the regulations allow.

D:Photos can establish with the same reliability what a government safety commission can.

E:There were verifiable cases of radiation sickness in the year before the plant was cited by the safety commission.
