The true statement about steamboat travel is:
Steamboats increased trade and profits because goods could be moved more quickly and cheaply.
Steamboats revolutionized transportation in the 19th century by allowing for efficient movement of goods and people along rivers, significantly boosting trade and economic development. The other statements are inaccurate. Steamboats did not rely on wind power, they could travel both up and down rivers, and they were capable of carrying both passengers and cargo.
