How to fix the first error
 What does output-write do?
 When in doubt read the instructions:
 http://ccl.northwestern.edu/netlogo/docs/
 Programming Guide > Output
 Find other examples of output-write in the
program.
 What should output-write "sim "
simulations do?
 Solution: output-write simulations
 Add a comment that you fixed it.

How to fix the 2nd error
 What should your first step be?
 The observer is the aspect of the program that executes a
procedure when nothing else does.
 Look at the procedures dependent and independent.
 What executes them?
 The macaques are asked to.
 Solution: ask the macaques to check mimetism:
ask macaques [
ifelse mimetism?
[dependent]
[independent]
]

Look at the interface
 Where is the go button?
 What does mimetism mean?
 Run the simulation with and without
mimetism. What is the difference?
