Question 3 • Economics and Personal Finance

Which form of transportation has led to more efficient business in a global market?

Answer
A
high-speed trains
B
cargo ships
C
helicopters
D
tractor trailers

Explanation

Cargo ships can carry very large quantities of goods across oceans at a relatively low cost per item. This makes international trade more efficient by moving products between global markets in bulk. High-speed trains, helicopters, and tractor trailers generally carry less or serve more limited routes. The correct choice is cargo ships.
