What does the graph tell us with regard to the researchers' question? O A. The graph indicates that people with TBI have, on average, different patterns of cognitive decline than people with no TBI. In particular, TBI seems to be associated with greater declines in processing speed and executive functioning, but does not seem to be associated with greater declines in the other domains. O B. The graph indicates that people with TBI have, on average, the same pattern of cognitive decline as people with no TBI. Across domains, the average performance of both groups seems to be less than that of the healthy, age-matched normative group. O C. The graph indicates that people with TBI have, on average, different patterns of cognitive decline than people with no TBI. In particular, TBI seems to be associated with greater declines in attention/working memory, learning/memory, and language, but does not seem to be associated with greater declines in processing speed or executive functioning. O D. It is not possible to tell from this graph whether the pattern of cognitive decline among the two groups is different, on average.
