Explanation:
The said query in SQL that selects all employees who were hired between July 1, 1991, and December 31, 1991.
All employees hired between July 1, 1991, and December 31, 1991 are included in the WHERE clause.
The "BETWEEN" is inclusive, so employees hired on December 31st, 1991 would also be included in the result set.
