There are five different categories of awards: movie awards, crew awards, director awards, writer awards and actor awards. A movie can only win an award after being nominated for the award. Your task is to answer the following questions using SQL queries. For each question, your answer must be a single SQL query that may contain subqueries, and you must write your answers into the template file myqueries.sql.

1.5 Which year was the youngest director (i.e., the youngest person in the database who has ever directed a movie) born in? List that year. (1 Mark)

1.6 How many crew members have won at least one crew award? List that number. (1 Mark)

1.7 What is the maximum number of scenes in any movie? List that number. (1.5 Mark)

1.8 Give the list of directors who have directed at least two American movies (i.e., produced in USA). Provide their ids and the number of American movies that they each have directed. (1.5 Mark)
