The correct answer to this open question is the following.
Although there are no options attached, we can say that when Derek writes his autobiography, he can just concentrate on recalling the events he experienced in the past, without thinking about the keystrokes he needs to hit. He uses explicit memory in recalling the past events, and implicit memory in hitting the right keystroke.
Scholars consider that you use explicit memory when people have to make a conscious effort to remember something. For instance, if you try to remember your friend's names from elementary school, you have to use explicit memory to make an effort and try to name some of your friends at that time.
On the other hand, when data, names, figures, or any information comes up easily to your mind, then it is said that you use your implicit memory. Ideas and memories easily come to your mind.
The correct answer is D. Johnny is engaged in the ethnocentrism.
Explanation
Ethnocentrism is a human ideology through which individuals analyze the world according to the criteria of their reality. It is a concept developed by anthropology to mention the tendency that leads a person or social group to interpret reality from their cultural parameters. Ethnocentrism supports the idea the own cultural group is the most important, or that some or all aspects of one's own culture are superior to those of other cultures.
Johnny's case is an example of ethnocentrism because he considers that only people who take pride in being workers, loyal supporters of the Republican Party, strong patriots and God-fearing Christians, are true Americans and this suggests Jhonny believes other cultural traits or group are inferior or not appropiate. So, the correct answer is D. Johnny is engaged in the ethnocentrism.
