Answer:
Spain was in debt from wars and Isabella and Ferdinand turned away Christopher Columbus's ideas of venturing/trading outside of Afro-Eurasia but once he promised to bring back riches (ie silver and gold) they granted his request and he set sail to "discover" what he thought was India but ended up in the Americas. This led to the development of 2 great trading systems: the Columbian Exchange and the Atlantic system. Things that were mostly traded were sugar, silver, and slaves (the 3 s's). Allowed Europe to venture out amongst Asian waters, which later inspired others to do the same (French, English, Dutch, etc).

stimulus discrimination
Explanation:
Mrs. Ridcully probably attempted that her conditioning (her own specific whistle) would eventually be generalized and other similar stimulus (dog owner's whistle) would generate the same conditioned response, but she failed.

Stimulus discrimination happens when the subject is able to differentiate between different stimuli, and will only respond to an specific stimulus.
