someone born during the u.s.-mexican war could
have been alive during the civil war.
a person could have been a child in both the
american revolution and civil war.

Explanation:

1. Check the first statement: The Revolutionary War (1775-1783) lasted 8 years, while the Civil War (1861-1865) lasted 4 years. So the Civil War is not the longest.
2. Check the second statement: The Constitutional Convention was in 1787, decades before the Civil War (1861-1865) even began. This is false.
3. Check the third statement: The U.S.-Mexican War was 1846-1848, and the Civil War was 1861-1865. A person born in 1848 would be 13 in 1861, so they could easily be alive during the Civil War. This is supported.
4. Check the fourth statement: The Revolutionary War ended in 1783; the Civil War started in 1861, a 78-year gap. A child in 1783 would be at least 85 by 1861, making it impossible to be a child in both. This is false.

Answer:

Someone born during the U.S.-Mexican War could have been alive during the Civil War.
