and in Tomorrowland Carousel of Progress, a tribute to electricity, was powered by gas. too

Answer 2

I can't figure out the word you've scrambled. But to answer the ques-

tion, I would say the run on a rail track. As once when I was on the

ride, it rumbled under the boat, like there was something rubbing or

sticking when we went around a corner. And that made me realize

we were not floating at all.

Answer 3

I would say "Natural Gas" but it looks like you're missing a couple of A's.
