Use Tympanogram #2 and Table 1 to answer the following:    True/False: If the patient was an adult, instead of a three year old, the ear canal volume would be considered normal in size. 

True/False: Results from frequency-specific ABR testing using tone bursts are closely correlated with pure tone behavioral hearing testing. 

Match the test features with the evoked response test type. Answers may be used more than once or not at all.  Assesses all three parts of the ear [options] Gives general Information about outer hair cell function [options2] Is not used in clinical practice [options3] Provides objective assessment of hearing sensitivity [options4] May not be sensitive to mild hearing losses [options5]

Use Tympanogram #2 and Table 1 to answer the following:    What does Tympanogram 2 suggest in terms of middle ear function? (Choose one)

True or False: Admittance and impedance have a supplementary relationship. 

Tympanogram #2: Assume patient is around 3 years old.     

Given your knowledge of evolution and natural selection consider the following scenario: A population of grasshoppers contains individuals that have either green or tan bodies.  The prairie where the grasshoppers live used to have grass plants with both green and tan colored leaves.  Recently, a disease has wiped out all the types of grass except those with the green leaves.  The effect on the grasshopper population would be that with each generation: A.  tan grasshoppers would develop slightly more green bodies, B.  there would be a greater proportion of individuals with green bodies, C.  there would be no discernible effect since there would be enough food for all grasshoppers. State your choice (A., B., C.) and provide the reasoning for the choice you made, briefly.   [Why did you pick A or B or C?]
