Unfortunately, sometimes inaccurate information can get entered because the statementhas a “True” truth value even if there is incorrect information in part of the statement. For eachstatement below, determine if the entry will get past the automated system or will be labeled with a“False” truth value and end up being returned to the sender.Notes:1.
