"The interviewee may confuse cars with trains. As Table 1 indicates a train consists of 2 front cars and 4 passenger cars." :) We have to produce 5 trains, but 20 cars...Slovakia does not have this excess capacity.
Hello Duarte, As Ian correctly remarked, read carefully, since it´s not about the traing but the cars. Devil is in the details :) Hope it helps! Cheers, Clara
