\nIn an exam, I would go into a bit more detail about the number of setups (always good to repeat your experiment to increase the sample size).

\nAnswers:
\n
\nA. Females are more likely to call the alarm when a ground predator approaches.
\n
\nB. The reason for females being more likely to give the special call when ground predators are approaching compared to males may be because females are more careful for their safety and for the safety of their kin.
\n
\nC. There is no real difference in which group would sound a warning call for aerial predators, the call is made by really any group.
\n
\nD. Any group of females that are part of some sort of family are more likely to sound a warning call for the approach of ground predators than that with no family.

\na. You visit your grandmother for a week\u2019s holiday. On the first night you are kept awake by a wall clock that chimes at quarter-hour intervals. By the end of the week you have no difficulty getting to sleep.

\n
\nc. i. A mother rings a bell each night to let her children know that the evening meals is ready and that they should come in from play. After a few days, the family cat also comes home in response to the bell and is fed at the same time. Occasionally, when the family is going out and they wish to lock the cat up, they ring the bell in the middle of the day. The cat comes home, but is not fed.
\n
\nThis was classical conditioning. The reward follows stimulus.
\n
\n
\nii. Predict what might happen if the cat is brought home regularly by the bell without feeding.
\n
\nThey cat may decide to not respond the bell after a while because it might realise the pattern of not receiving food.
\n
\n
\nd. A model bird made of red and white feathers was fiercely attacked when it was first placed near a robin nest in spring. After several days, the robins ignored the model.
