Answer to Question 1

A

Answer to Question 2

Dairy cows are conditioned to let down their milk as they enter the milking parlor, because they associate entering the milking parlor with being milked. Similarly, a horse may learn to open a gate by tinkering with the latch mechanism until it learns the proper sequence to open the latch.
