Physiological research has uncovered disturbing evidence linking a number of structural disorders to jogging. Among the ailments seemingly connected with this now-popular sport are spinal disk displacements, stress fractures of the feet and ankles, knee and hip joint deterioration, and tendonitis. Furthermore, these injuries do not occur exclusively among beginning runners veteran joggers suffer an equal percentage of injuries. What the accumulating data suggest is that the human anatomy is not able to withstand the stresses of jogging.
Which one of the following is an assumption of the argument?
(A) The link between jogging and certain structural disorders appears to be a causal one.
(B) Jogging causes more serious disorders than other sports.
(C) The jogger's level of experience is a factor determining the likelihood of a jogging injury.
(D) Some sports are safer for the human body than jogging.
(E) The human species is not very durable.
Premises:
- Jogging and certain structural disorders seem to be connected.
- These injuries are seen among beginner and veteran joggers.
Conclusion: Human anatomy is not able to withstand the stresses of jogging
The premises tell us that Jogging and certain disorders are linked. The conclusion says that human anatomy is not able to withstand jogging. The premises do not tell us that jogging causes these disorders. It just tells us that there is a connection. But the conclusion assumes that jogging causes these disorders and human anatomy is not able to withstand it.
But the connection could be because of something very different. Perhaps the joggers usually like to jog in the early morning since there are fewer vehicles on the road and waking up early is what causes these disorders.
Hence option (A) is an assumption made in the argument. That the link is a causal one. That jogging causes disorders.
