Marshall ate a hamburger he purchased from his favorite fast food restaurant. An hour later his stomach became very upset and he spent the rest of the evening vomiting. A week later he entered the restaurant and immediately became nauseous when he saw a hamburger. Marshall's nausea when he saw the hamburger is an example of: a. classical conditioning.
b. observational learning.
c. imitation.
d. operant conditioning.

a. classical conditioning.

hope this answer correct (^^)

the fourth amendment protects:

"the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."  

so this would mean the denial to search and seizure without warrant or permission.

can you explain it better
