The figure belоw shоws the mаrket fоr t-shirts in Wonderlаnd. The domestic price is $20. Once trаde is allowed, the price drops to $15 and 3 million of t-shirts are imported. Image Description This graph shows price (P) on the vertical axis and quantity (Q) on the horizontal axis. A downward-sloping demand curve intersects an upward-sloping domestic supply curve at point E, where price is 20 and quantity is 2. A second upward-sloping supply curve labeled domestic supply plus imports intersects the demand curve at point A, where price is 15 and quantity is 4. Dashed guide lines mark prices 20 and 15 and quantities 1, 2, and 4. On the left axis, point B is above price 20 and point D is near the lower supply intercept. The graph divides several welfare regions labeled a, b, c, d, and e. Area a: The triangle above price 20 and below the demand curve, to the left of quantity 2. Area b: The rectangle-like region below price 20 and above price 15, between the vertical axis and quantity 1. Area c: The region below point E and above price 15, between quantities 1 and 2. Area d: The region below point E and above price 15, between quantities 2 and 4. Area e: The lower-left region above the domestic supply curve, below price 15, and left of quantity 1. Point E marks the domestic market equilibrium. Point A marks the equilibrium when imports are included, lowering price from 20 to 15 and increasing quantity from 2 to 4. Based on the figure above, match the right and left sides correctly:
