Read the following paragraph and answer the question at the bottom:

1. Electroencephalograph (EEG) is a tool used for gauging and recording brain

2. waves. In 1929, Hans Berger, the German psychiatrist, published the results of

3. his experiments using electroencephalograph in recording human brain

4. waves.

5. Four major brain waves exist: alpha has a frequency that ranges from 8 to 14

6. cycles per second (cps) and is found in the occipital part of the brain. Beta

7. covers 14 to 30 cps. Delta wave includes frequencies that are below 5 cps. Theta

8. wave covers the range between 5 to 8 cps. Alpha waves are more active

9. during relaxation and light sleep. Nonetheless, there function is altered by deep

10. mental activities. Beta waves, on the other hand, appear during mental

concentration periods.

12. In 1935, the findings of collaborators Frederic Gibbs, William Lennox, and

13. Hallowelle Davis from Harvard on the use of EEG in epilepsy was published.

14. Since EEG poses no pain or side effects, it is broadly included as a medium for

15. identifying brain irregularities. The EEG is instrumental in discovering a host

16. of brain wave abnormalities. Person who suffer from grand mal epilepsy have

17. brain wave patterns that resemble the spikes, while with those with petit mal epilepsy

18. have arch-shaped brain waves. Brain waves respond to physiological and

19. chemical stimuli. For instance, the use of drugs will result in low-amplitude,

20. high frequency brain waves. When we are sleep, the waves' pattern changes a

21. few times. Dreaming frequently happens when the brain waves have high

22. frequency but low amplitude.

According to the passage, Beta waves are active during which of the following ?

Correct! Wrong!

The answer to this question is directly stated in lines 10-11, therefore B is the correct answer.

The word "recording" in line 1 is closest in meaning to

Correct! Wrong!

The logical choice is (A). Once the EEG measures the brain waves, it has to "register" them.

Correct! Wrong!

The word "it" refers to EEG in line 14.

Read the following paragraph and answer the question at the bottom

1. The leading causes of amnesia are either physical or psychological. In

2. antergrade amnesia, the subject is unable to recall the events that occur after

3. a shock or an injury to the brain; however, past memories will not be lost. In

4. retrograde amnesia, the patient is capable of recalling events that occurs after the

5. trauma; interestingly enough, information stored before the shock, is lost and

6. cannot be retrieved. In paraamnesisa, established memories are contorted. In

7. psychogenic fugue, the subject may venture into a new lifestyle, trying to

8. repress memories which lead to trepidation. The events happening during

9. psychogenic fugue are non-retrievable. Nonetheless, the experiences that

10. happened before the onset can be recovered. Among the most popular

11. treatments for psychologically related amnesia are psychotherapy, the use of

12. drugs, and hypnosis.

In line 8, the word "trepidation" could best be replaced by

Correct! Wrong!

The passages says that "In psychogenic fugue, the subject may venture into a new lifestyle, trying to repress memories which lead to trepidation." If the word "trepidation" were replaced by "anxiety," the meaning would be kept the same.
