An electrician must complete both a six-month training course and an apprenticeship, in that order. If Paul has first completed an apprenticeship and then his training, he is qualified to be an electrician.

Which of the following contains flawed logic most similar to the original passage?
  1. Ella can go to either an opera or the ballet tonight. But Ella hates both, so she will go to neither.
  2. Arla must finish two more classes in order to finish her degree. Ella finished one course and will finish the other next week, so she will receive her diploma.
  3. Whales eat both shrimp and plankton, but never both together. Isla saw an animal eat both shrimp and plankton together, so it was not a whale.
  4. Cable TV does not work without having both a red cable and a blue cable connected first, and then a yellow cable. The TV has both red and blue cables connected, so it is able to work.
  5. May bought spaghetti and tomato sauce, ingredients necessary for her dinner. However, she forgot garlic, so she will be unable to cook spaghetti tonight.
Explanation
Answer: D - The passage containing flawed logic most similar to the original passage is in answer D. In the original passage Paul did not fulfill all of his requirements in the correct order, so he is not qualified to be an electrician. In answer D, the TV has two, but not all three of the cables connected, so it is not true that the cable TV will work.
