Passage Summary: Joe thinks vampire stories make no sense because everyone would eventually be a vampire; Maria points out that in most stories, most victims just die instead of turning.

Reasoning: Joe argues that vampire lore is logically impossible because of exponential growth in the vampire population; Maria counters that the premise of 'every victim becomes a vampire' is not actually a standard feature of most stories.

Analysis: Joe's entire argument rests on the premise that 'every victim of a vampire becomes a vampire.' Maria explicitly contradicts this by saying that in most stories, vampires turn only a few of their victims. Therefore, the point at issue is whether it is a standard feature of vampire stories that every victim is transformed into a vampire. Joe says yes (it's why they are absurd), while Maria says no. Use the 'Agree/Disagree' test to confirm that one speaker would say 'True' and the other 'False' to the correct answer.
