Dr.Kang,a cognitive psychologist,conducts an experiment examining the effect of emotion on memory.He provides lists of 15 words to two groups of participants at his university.He puts the names of all the participants in a hat.The first 20 names he assigns to Group A,and the last 20 he assigns to Group B.Group A is given a list of words that are very emotional in content (e.g. ,passion,murder).Group B is given a list of words that are neutral in content (e.g. ,houseplant,desk).He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university.He finds that Group A remembers 15% more words than Group B.

-Dr.Kang can make a causal claim that "emotion enhances memory" for all of the following reasons EXCEPT:
A)He used a large number of participants
B)There is a numeric difference between Groups A and B
C)Reading the words occurred before recalling the words
D)Dr.Kang treated Groups A and B identically except for the emotional word content

The size of the sample does not directly support a causal relationship between emotion and memory. While a large sample size is important for statistical significance, it does not necessarily establish causality. The other three options do support a causal claim: there is a difference between the emotional and neutral groups (B), the order of reading and recall is controlled (C), and the groups were treated identically except for the emotional content (D).
