Which subject(s) were studied by scientists born in France (return just the unique subject name) SELECT from WHERE AND AND ISO_Code = 'FR'; Which subject(s) were studied by scientists born in France (return just the subject name, and display that subject name only once) SELECT from research_area, scientist_subject, scientist where research_area.subject_code = scientist_subject.subject_code and ID = Scientist_ID and Please answer all parts of the question. Which scientists have an "a" in their names and studied a subject which contains an "e"? DISTINCT ,subject FROM \begin{tabular}{l|l} WHERE & .subject_code = \\ .subject_code AND & \end{tabular} AND LIKE LIKE J and research_area.Subject like '\%e\%'; Swap the first name and surname of scientist with ID = 1 using variables Alter the Events to add the attribute "Cancelled" using the appropriate MySQL datatype for TRUE FALSE. Clue: use the MySQL standard command for TRUE or FALSE (binary options) Using a subquery to find the Scientist.ID, add the subject Mathematics for Maryam Mirzakhani VALUES ((SELECT WHERE =
