The passage indicates that computers can become more accurate and effective in translation tasks when they rely less on human guidance, thanks to unsupervised learning. This autonomy in learning supports the idea that computers can achieve superior performance in certain areas, suggesting that they may surpass human intelligence for specific tasks. Thus, the most appropriate choice is D: successful when there is less human involvement.

The details highlight that computers achieve greater accuracy and success with less human involvement, supporting the notion that they can be smarter than humans in specific tasks. The use of unsupervised learning allows these systems to learn independently, outperforming traditional supervised methods. This illustrates how technology can advance beyond human intervention in certain domains. ;
