Feedback: As in your explanation, the SQL query returns a table with 2
columns, the name and the nationality of the host with the youngest age. The
question returns 2 columns, the name and the nationality of the oldest host
. So the SQL prediction above is wrong. Please fix the SQL.

SQL: SELECT name, nationality FROM host ORDER BY age DESC LIMIT 1

The execution of the SQL query above would return a table with 2 columns.
The first column, "name" would contain the name. The second column, "
nationality" would contain the nationality. With "ORDER BY age DESC", the
table is sorted in descending order. With "LIMIT 1", the table only includes
the first record, which is the oldest host. So the SQL query returns a
table with 2 columns, the name and the nationality of the oldest host.
