How is the structure of B different than the structure of D?

Hi @mahosmar, I think it's easiest to visualize this one in relation to the passage itself. Passage: Almost every SP in the past had TVA VB has TVA Therefore, VB will probably be SP Answer choice (D): Almost every P in the past had PHD R has PHD Therefore, R will probably be P As you can see, these two have exactly the same pattern of flawed reasoning. Comparatively, this is answer choice (B): Almost every P has 10YE D will probably be P Therefore, D has 10YE Hope this is helpful! Please let us know if you have any further questions.
