单项选择题

Directions:This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
In all human communication, information is sent from one person’ s memory to another. No matter how the message is sent, it must arrive in a form that can be understood, retained, and later recalled by the brain. How do these three memory processes function Before answering this question, we need to consider the fact that there are two kinds of memory:short-term memory and long-term memory. Psychologists know a great deal about the former kind of memory, but they know very little about the latter kind.
Your short-term memory can hold only five to seven "bits" or items of information. However, unless you repeat that information to yourself over and over again, you will forget it in less than a minute. This temporary memory is used when you try to remember a name or telephone number that someone told you a moment ago. Short-term memory plays an important part in thinking and understanding.
Short-term memory can become long-term memory. The process is influenced by age, genetics, hormone and environment. But the process of how many photographs are stored and later recalled still remains an unanswered question. What influence the process of turning short-memory into long-term memory

A. Age, genetics and hormone.
B. Age, genetics, hormone and environment.
C. Only environment.
D. Genetics, hormone and age.
