Complex sentence: If Bell's reasoning is correct, then the experimental results appear to demonstrate that some quantum effects travel faster than light, and the class of tenable "hidden variable" theories are limited to the non-local variety.
Split into simpler sentences: If Bell's reasoning is correct, then it leads to the conclusion that no local hidden variable theory can account for such results. The experimental results thus appear to demonstrate that some quantum effects travel faster than light, and the class of tenable "hidden variable" theories are limited to the non-local variety.
