A$.$

Selling expense has increased due to the increase in cost of goods sold.

B$.$

The level of interest as a percentage of sales has increased$$ significantly; this suggests that the firm has too much debt.

C$.$

Sales have declined and cost of goods sold has increased as a percentage of$$ sales, probably due to a loss of productive efficiency.

D$.$

Operating expenses have decreased as a percentage of$$ sales; this appears favorable unless this decline has contributed toward the fall in sales.

E$.$

Further analysis should be directed at the increased cost of goods sold and the high debt level.
