Question

which economic activity is most prominent in japan? 1. farming 2. fishing 3. exporting natural resources 4. importing automobiles

Answer 1

I would say 2 because they are surrounded by water and fishing is major for countries including agricultural, but finding natural water to farm large amounts would be complicated due to their location.

Answer 2

*cough* anime *cough* video games

In all seriousness, I'd go with 4.

Mazda, Nissan, Suzuki and Toyota are all a few examples...
