huolympics1-8, Exercise 3: A neutral statement on doping

Model answer:

"A state doping programme in East Germany has been documented by investigations after the end of the Cold War, and some Hungarian athletes also tested positive in the period. The scale and organisation of doping in Hungary are less well documented and remain disputed, so no individual result should be assumed to have been affected without evidence."

Any pair of sentences that separates the documented from the uncertain and avoids naming individuals without evidence is acceptable. Details should be checked.
