An employer says, "If racial quotas are adopted for promoting employees, then qualified employees will be passed over; but if racial quotas are not adopted, then prior discrimination will go unaddressed. Either racial quotas will or will not be adopted for promoting employees. Therefore, either qualified employees will be passed over or prior discrimination will go unaddressed." Let "R"="Racial quotas are adopted", "Q"="Qualified employees are passed over", and "P"="Prior discrimination goes unaddressed". In that case, the argument can be written as the following:.
1. R  Q
2. ¬R  P
3. R  ¬R
4.  Q  P
