The next question is physical: they are all tied together at the wrist and tangled up. Oh, we used to do this in gym class all the time. They have to get untangled. They can't. They pass. Someone in the forums posted the trick to this one too.

The seventh question requires them to pick out how many triangles are in a diagram. Oh, again I'm so bad at these. I always miss a bunch. They guess twenty-four, and then twenty-eight. The answer if forty-four. I guess they miss a bunch too.

The last question is: How many pairs of animals did Moses take on the ark? Trick question. Read it again. Jennifer figures out that it was Noah, not Moses, who went on the ark, and the answer is zero.

Anderson tells them that they have earned $75,000, and now they are going to go on a tour of the building. A tour? The group walks down many hallways, up and down stairs, and in and out of rooms. Anderson voice-overs that "the tour is part of the trap." They're trying to bore them to death? As they filter into a room, Anderson tells them what the trap is. On a monitor, they see the second group starting to tackle the same eight-problem test the first group just finished. What the second group doesn't know is that for every problem they solve correctly, $15,000 will be subtracted from what the first group won. The only way to stop them is to pick a runner to go back to the room and tell them, but given the circular nature of the tour, it might take the runner a while to find his or her way back. The group quickly picks Jim, who takes off, down a hallway.

Jim, running. Second group, working on the second question. First group, watching on the monitor. Ominous music plays. Jim looks confused. That pretty much sums up the next five minutes or so. The second group solves the second question, so they've lost $30,000. Jim runs into the room and yells, "Stop!" The second group cheers, because they see it on the monitor. Jennifer yells out that they've only lost $15,000, which is incorrect, but whatever. Jim tries to explain why they should stop. Charlie doesn't get it. Jim over-explains it. He should just say that the second group cannot earn any money, and in fact loses money when they get questions right. According to Anderson, the second group is "confused by Jim's explanation, and seems reluctant to trust him." The first group can see what's going on, but not hear them talking. Kate is pissed that Charlie is causing a controversy. Henry figures out that the second group thinks that Jim is The Mole, and trying to sabotage. Um, how obvious would that be? What a stupid idea. Kate tries to pin suspicion on Charlie, saying that he was the first to suspect Jim as The Mole. Steven finally figures it out, and says that they'll stop. Anderson says that "even though the test is over, doubts still linger." Charlie and Steven continue arguing with Jim. The first group enters the room. Anderson tells them that they "started them off a little late." I think he's referring to the fact that when the first group finished their tour, the second group had already started solving problems. Thus, the group only loses $15,000 off their total, making their winnings on this test $60,000. Everyone cheers. The total pot is at $310,000. Henry says that he thinks The Mole was at work on this test, but he doesn't know exactly what.
