 Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 18 to 25.

The three phases of human memory are the sensory memory, the short-term memory, and the long- term memory. This devision of the memory into phases is based on the length of time of the memory.

Sensory memory is instantaneous memory. It is an image or memory that enters your mind only for a short period of time; it comes and goes in under a second. The memory will not last longer than that unless the information enters the short-term memory.

Information can be held in the short-term memory for about twenty seconds or as long as you are actively using it. If you repeat a fact to yourself, that fact will stay in your short-term memory as long as you keeprepeating it. Once you stop repeating it, either it is forgotten or it moves into long term memory.

Long-term memory is the huge memory tank that can hold ideas and images for years and years. Information can be added to your long-term memory when you actively try to put it there through memorization or when an idea or image enters your mind on its own.

The expression “is based on” in the first paragraph could be best replaced by______________

A. Is on the top of

B. is at the foot of

C. depends on

D. is below
