Card 23 / 54: Professor Henry Higgins' laboratory just finished a study on music and language. They asked whether there was any relationship between musical expertise and the ability to learn a foreign language. In the first part of their study, participants took a test of musical ability, and then they learned how to say 100 words in the new language. The results of this experiment are in the graph below. Prof. Higgins asked four of his grad students to provide an explanation of the datA) Based on your knowledge of correlations, whose explanation do the data best and most accurately support?
A) Tracy: "People who learned more words also had greater musical ability, therefore music and language rely on the same mental processes."
B) Jean: "People who learned more words were also more likely to have greater musical ability, therefore we can use someone's score on the music test to predict how many foreign words they will learn."
C) Sam: "People who learned more words also tended to have better musical ability, therefore having good language skills helps you be a better musician."
D) Pat: "People who had better musical ability learned more words, therefore being a good at music helps you learn a foreign language."
