T-ara's Jiyeon joined the ranks of 'powerful female idols' yesterday on MBC's "Quiz to Change the World." Jiyeon started off by revealing, "My body was so weak, I began learning Tae Kwon Do when I was five in order to get stronger. I took lessons for 7 years and am a level three." In order to prove her story, she got up to smash five pine boards stacked one on top of the other, and shocked the studio with her skill. Despite witnessing the feat from the very front row, 2AM's Jinwoon refused to believe in her strength: "Did they cut it up beforehand?" Jiyeon then went on to smash eight pine boards easily, making many wonder whether she could do ten. Although she showed confidence in her ability to, the studio became concerned over her safety. MC Lee Hwi Jae later asked Jinwoon, "Jinwoon, you're the same age as her. Do you think you can smash 10?" Jinwoon answered with a surprised tone, "Me? The only thing I learned in Tae Kwon Do was how to say, 'Our teacher is so cool!,'" putting the studio in a fit of laughter. Check out Jiyeon's power display below: Fellow members Hyomin and Boram appeared alongside Jiyeon for the show as well. Hyomin prepared special voice imitations for her segment, in which she imitated the voices of Kang Yoomi ("Kang Teacher in the Dressing Room"), An Sung Daek ("Hello, Francesca"), and Jung Jun Ha ("No Brain Survivor"). She went on to state, "There's a lot of seniors here today so I prepared a song that everyone would know. I would like to dedicate this song to Lee Jung, who was just discharged from the marines." Hyomin then began playing a guitar and showed off her hidden vocal skills by singing, "I'll Give You All of My Love." Check out the video of her performance below: T-ara later received a question from MC Park Misun, asking, "Which member has the most old-fashioned tastes?" Leader Boram answered, "It's actually 18 year old maknae Jiyeon. You'd think that she'd like sweet foods such as cheesecakes or chocolates, but she actually likes heavy, spicy foods such as 'sundaeguk' (blood�sausage in beef stock) and 'haejangguk' (soup eaten for hangovers)." 2AM's Changmin, who observed her answer, added, "Compared to our maknae Jinwoon, Jiyeon is on the more luxurious side. Jinwoon enjoys eating skate, marsh snail, and haejangguk as well. We always make fun of him by saying he's 20 years old, but his eating preferences makes him seem like he's 80."
