  a. An intelligence test that has quantitative items.
  b. A norm-referenced middle grades math achievement test.
  c. A math aptitude test.
  d. An oral test she conducts with each student that is based on concepts she has taught.

Answer to Question 1

B

Answer to Question 2

With variable interval schedules of reinforcement, the individual is rewarded after an average time interval. VI schedules tend to produce very consistent or steady patterns of behavior because the respondent never knows when the reinforcer will be awarded next.
