Such an exuberant welcome from a usually sedate audience both pleased and surprised the guest speaker.
"The school buses lined up like tanks on the battlefield, strategically parked to protect people."
This sentence uses figurative language. It uses a simile, comparing school buses to tanks using words such as 'like' and 'as'.
The second sentence uses imagery with the words 'bright' and 'shiny', but this is not what the question is looking for. Hope this helps.
