Shonie did not study for the chemistry exam, so she is hoping the exam will be a <u>multiple choice</u> test because that type of test gives the most help for retrieving information stored in long-term memory.
<u>Explanation</u>:
Long-term memory (LTM) is the space to store informative knowledge. The LTM enables memory to remain in our brain for a longer period of time. The ability of brain to retain LTM is unlimited.
Information can be stored and retrieved permanently from the LTM. The information stored in the LTM will be available throughout the life of the person.
Multiple choice questions provide different choices for a question in which the respondent can choose the correct answer from the choices. Multiple choice test helps Shonie to retrieve the information stored in long-term memory and do the test well.
The predominant form of social organization in the tropical rain forests of western and central Africa was small-scale societies led by local councils.
In a small-scale society, a person interacts with the same people in almost all social circumstances, but in a large-scale society, a person has a variety of impersonal or part-relationships, some of which are fleeting and others which are enduring, and both of which do not always overlap.
There are generally few such positions in small-scale social organization , and those that do exist tend to be integrated with the ruling class. Agrarian societies, hunting and gathering societies are a few examples of small-scale societies.
People who produce and maintain agricultural goods make up agrarian communities. Another indicator of an agrarian civilization is how well-off a nation is in agricultural output. Thus the small social organization led by local councils are more predominant in the tropical rain forests of western and central Africa.
