 \paragraph*{Task 2, Russian Roulette (1 easy and 2 normal points)}
-Implement Russian Roulette, with a minimum guaranteed depth of 4, according to the slides.
-Russian roulette must be parameterisasble from the scene file.
-It's probably easiest to start with a version that uses a fixed continuation probability in each bounce (1 Point). Check the slides for details.
+Implement Russian Roulette, with a minimum guaranteed depth of 4.
+Whether or not Russian roulette is used must be parameterisasble via  boolean \texttt{rr} from the scene file.
+You can start with a version that uses a fixed continuation probability in each bounce (1 Point). Check the slides for details.
 
 However, the proper way to do it is to keep track of the \textit{throughput}.
 With every bounce, the importance emitted from the camera is attenuated, and the probability for continuation should become lower.
