Question

Which disadvantages did steam power in boats and trains when they were first introduced?

Answer 1

B. and D.

I believe, but I am not 100% sure!

Answer 2

I think that one of the reasons as to why steam power in boats and trains were at a disadvantage is that they’re big and heavy, expensive to maintain (increased costs) and i’m not quite sure about the second option but I think that maybe it may lead to more accidents? (they all seem quite likely)
