M: I'm here with Margaret Seabrook, the CEO of creative toys. In today's show, we're going to discuss the hottest new toy of two thousand seventeen, the Super Spinner. Margaret, welcome. ,F: Thank you, Brian. It's great to be here. ,M: OK, so tell us about this new toy. ,F: Well. It's similar to a relaxation ball in its function, but it's useful for anyone who has problems focusing. ,M: So how does it work? ,F: It's about the size of a cookie and it has 3 small round parts that can move in any direction. Basically, you just hold it in between your thumb and middle finger and spin it. That's it. ,M: That's it? ,F: Yeah, it's very popular. Not only with children, but with adults as well. ,M: A professor at MIT by the name of Jill Mean Lee has publicly stated there is no scientific or medical evidence for your claims about its benefits. Many schools also have banned the toy, saying it leads to a lack of focus in the classroom. ,F: Well, that professor is allowed to have her opinion. ,M: Fair enough, and who invented it? ,F: Catherine Hettinger, a chemical engineer, was first believed to be its creator. But then we found that an IT professional named Scott McCoskry was the actual inventor.
(A) M: So, the biological engineer was first believed to be its creator, but the actual inventor of the toy is an academic researcher? (B) M: So, the chemical engineer was first believed to be its creator, but the actual inventor of the toy is an IT professional? (C) M: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (D) M: So, Catherine Hettinger was first believed to be its seller and the actual inventor of the toy is a chemical engineer?
