Suppose that autoworkers are unionized. If autoworkers choose to abolish their union, then the quantity of autoworkers demanded will?

Answer: Rise

Explanation: Unions benefit workers by being able to bargain for higher wages, better hours that ensure work-life balance and other workplace conditions that are favorable to employees. When the autoworkers are unionized, it is likely that they have higher pay which will reduce the quantity of autoworkers demanded.

If the union is abolished, their wages will fall, and other conditions will vary across the industry according to what the employer feels comfortable offering their employees, thereby increasing the demand for autoworkers.
