The Democratic Party is one of the two major contemporary political parties in the United States, along with the Republican Party. Tracing its heritage back to Thomas Jefferson and James Madison's Democratic-Republican Party, the modern-day Democratic Party was founded around 1828 by supporters of Andrew Jackson, making it the world's oldest political party.
The modern-day Democratic Party is more than 150 years old and less than 300 years old.
It's definitely correct because 1828 is more than 150 years ago, and also less than 300 years ago. It's difficult for the system because the statement involves complex logic with more than 1 comparison.
