Choose the correct version of the combined sentence.

The correct version of these two sentences when combined is:

When we were in Europe on vacation, we usually flew on airplanes; however, sometimes we took the train.

When we were in Europe on vacation, we had the opportunity to experience different modes of transportation. Flying on airplanes was our usual choice for long distances, but occasionally, we decided to enjoy the scenic views and slower pace of traveling by train.

By combining the two sentences with a semi-colon and the conjunction 'however', we can clearly show the contrast between the two modes of transportation. The use of the semi-colon indicates that the ideas are related but distinct, while 'however' highlights the shift in actions from flying to taking the train during our vacation in Europe.
