In a related study, another experimenter-given cue was to place a marker in front of the correct object. Zwerg successfully chose the object with the marker 26 out of 48 times. Does this result show that Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time?
a. What are two possible explanations for Zwerg’s results of choosing the correct object 26 out of 48 times?
b. Which explanation of the two suggested in part (a) do you think is the more plausible, based on Zwerg’s results? Explain based on your intuition.

c. If Zwerg is just randomly choosing between the objects, what is the chance that she will choose the correct object?
