Lee Dong Wook meets with the trainees once again to announce the next challenge. The trainees are tasked to perform live in groups based on positions they want to debut in: vocal, dance, rap, or "X" . "X" is a new position that requires trainees to perform two of the three aforementioned positions simultaneously. There are four songs for vocals (Paul Kim's "Me After You", Hwasa's "Twit", Bolbbalgan4's "To My Youth", and Wanna One's "Day by Day"), three songs for dance (Imagine Dragons' "Believer", Bruno Mars' "Finesse", and Jason Derulo's "Swalla"), two songs for rap (Zico's "Say Yes or No" and Haon, Vinxen's "Barcode"), and two songs for "X" (Charlie Puth's "Attention", for vocal x dance, and SMTM4's "Turtle Ship", for rap x dance). Each song has a member limit and would be picked by each trainee based on their ranks: Kim Yohan who ranked 1st from the first elimination round would have the privilege of choosing the song he wants to perform first. The winner from each performance in the vocal, dance, and rap positions will receive 100 times their votes while the winner among all songs of each category will receive 100,000 votes. For the "X" position, the winner from each performance will receive 200 times their votes while the overall winner will receive 200,000 votes. After each performance, they are ranked in their groups first and then overall in the category. Lee Dong Wook also announces that only the top 30 trainees will remain in the next round. Only five groups are covered this week. (Source: Wikipedia)
