Existing gene therapies that achieve various medical ends, such as boosting the production of red blood cells for anaemics, or strengthening muscles for those with a wasting disease, are also of interest to enhancers. Doping agencies are worried that athletes will use such treatments, which are hard to detect, in competitive sport. As early as 2006 a German trainer reportedly tried to get hold of an experimental gene therapy called Repoxygen, although there is no evidence that he was successful.

Which of the following can be properly inferred from the information above?

A) Gene therapies are predominantly used for enhancement rather than medical treatment
B) The efficacy of gene therapies for athletic enhancement remains unconfirmed
C) Doping agencies approve some gene therapies for medical conditions
D) Athletes avoid gene therapies due to strict detection capabilities
E) Repoxygen became widely adopted after 2006

Show SpoilerHints
Focus on quantifiers—'interest' ≠ 'use'; 'reportedly tried' ≠ 'achieved'
Show SpoilerExplanations

A) Violates scope: text compares interest (enhancers) and worry (agencies) but shows therapeutic origins
B) Correct: explicit 'no evidence of success' for historical attempt + worry about detection implies unproven application
C) Distortion: agencies express regulatory concern, not approval
D) Contradicts text: detection challenges suggest use advantage, not avoidance
E) Extreme: single trainer's attempt ≠ widespread adoption, and no follow-up data

Inference must be justified by text. (B) synthesizes evidence gap (Repoxygen) with undetectability concern. Others conflict with explicit information.
