Armtech, a temporary-employment agency, previously gave its employees 2. 5 paid vacation days after each 700 hours worked.

Some geologists argue that if oil is as common in unsampled areas of the world as it is in those already sampled, our current estimate of reserves that exist underground must be multiplied by a factor of 10,000. From this we can conclude that we can meet the oil needs of the entire world for at least five centuries, even assuming that future consumption grows at an accelerating rate. To reach the stated conclusion, the author must assume which of the following
A. It is possible to recover the oil contained in unexplored areas of the world.
B. The consumption rate for oil will not grow rapidly.
C. Oil will remain an important energy source for at least 500 years.
D. The world will achieve and maintain zero population growth.
E. New technology will make oil discovery and drilling more feasible than ever before.
The brains of identical twins are genetically identical. When only one of a pair of identical twins is a schizophrenic, certain areas of the affected twin’s brain are smaller than corresponding areas in the brain of the unaffected twin. No such differences are found when neither twin is schizophrenic. Therefore, this discovery provides definitive evidence that schizophrenia is caused by damage to the physical structure of the brain. Which one of the following is an assumption required by the argument
A. The brain of a person suffering from schizophrenia is smaller than the brain of anyone not suffering from schizophrenia.
B. The relative smallness of certain parts of the brains of schizophrenics is not the result of schizophrenia or of medications used in its treatment.
C. The brain of a person with an identical twin is no smaller, on average, than the brain of a person who is not a twin.
D. When a pair of identical twins both suffer from schizophrenia, their brains are the same size.
E. People who have an identical twin are no more likely to suffer from schizophrenia than those who do not.
