please help answer these questions regarding R, S configuration and drawing the different most stable projections

(8 points) Determine the configuration ( R or S ) of the stereogenic (chiral) centers are found in the structure of kabweol (a compound found in unfiltered coffee). The configuration of center 1 is: The configuration of center 2 is: The configuration of center 3 is: The configuration of center 4 is: 2. (8 points) Using the chair template provided, draw molecule A (below) in the most stable chair conformation. Pay close attention to the relative orientations ("up," "down") of the different substituent groups and to their relative positions around the ring.

(4 points) Redraw each of the compounds below as planar projections, using wedges and dashes on a cyclobexane (i.e. as used in the first drawing of A in problem 1). 3. continued
