Please help me with this database SQL questions refer to the picture below. Thank you in advance.

1) Compare the average sale price of race bikes in 2006 based on the type of down tube(e.g., Carbon, Aluminum, Titanium, or Cro-moly). Hint Use TubeMaterial table with link back to bicycle.

2) Using a UNION query, list the employees who painted bicycles on March 15, 2012 or framed them on that date (StartDate) (or both). Hint There are two columns on the bicycle table which are FK back to employee Painter and FrameAssembler. The Painter column in the bicycle table which represents the employee ID that did the painting. The FrameAssembler would be the employee ID of the framer.
