I want to know the answer to the following question:
How many wildcard contestants were chosen?
All the background I'm provided with is that "The wildcard round returned in season eight, wherein there were three groups of twelve, with three contestants moving forward – the highest male, the highest female, and the next highest-placed singer - for each night, and four wildcards were chosen by the judges to produce a final 13.". Is that enough to answer the question?
Answer: yes
