A sandhog claims that he has a list of thirty deceased workers who worked as a group on a tunnel that cut through a radon-intense area. He started his list after an oncologist reported that the incidences of cancer among sandhogs were five times greater than the incidence of cancer among other construction workers. The tunnel contractor states that its records show that no sandhogs working on the tunnel were exposed to more radiation than was safe.

A) The medical records of the oncologist were accurate
B) All thirty of the deceased sandhogs died of radiation-related cancer
C) The contractor has denied requests to inspect its radiation records
D) Sandhogs contract illness at higher-than-normal rates
E) The remaining sandhogs that worked on the tunnel show no signs of illness

2- Which of the following conclusions can be drawn most reliably from the passage?
A) Radiation did not cause cancer in the sandhogs
B) The contractor is not being truthful about the radiation
C) The records of the contrator are likely to be inaccurate or incomplete
D) The sandhogs were exposed to radiation elsewhere rather than in the tunnel
E) There is disagreement about the level of radiation that is safe
