Two scientists at a conference on evolution take to the stage on day 3 to argue their theories against one another. Each is a devout student of their own philosophy. The first scientist contends that organisms evolved via the increase of organs that were used the most during their time. They would then pass these on to subsequent generations. The second scientist, however, believed that advantages each organism possessed were absent for a long time, randomly occurred, and when they were beneficial, that organism would rapidly populate the population over a short period of time, evolutionarily speaking. Which of the following statements would strengthen the second scientist’s argument?
A) A study shows that bodybuilders who train more have larger children.
B) A taxonomy study that shows long periods of stagnant growth followed by short burst of massive evolution.
C) A study that showed a species who were more successful due to the things they learned over their lifetime that they passed on to their children.
D) A study that showed a consistent amount of time between the emergence of each new species.
What is B?
A taxonomy study that shows long periods of stagnant growth followed by short burst of massive evolution.

Which of the following best represents the relationship between a predicate act and a proximate cause, in the context of the authors discussion of the MBTA?
