Although instinct enables organisms to make complex responses to stimuli, instinctual behavior involves no reasoning and requires far fewer nerve cells than does noninstinctual (also called flexible) behavior. A brain mechanism capable of flexible behavior must have a large number of neurons, and no insect brain has yet reached a size capable of providing a sufficiently large number of neurons.
Which one of the following can be properly inferred from the statements above?
(A) The behavior of organisms with elaborate brain mechanisms is usually not instinctual.
(B) Insect behavior is exclusively instinctual.
(C) All organisms with brains larger than insects’ brains are capable of some measure of flexible behavior.
(D) All organisms with large brains are biologically equipped for flexible behavior.
(E) Only organisms with brains of insect size or smaller engage in purely instinctual behavior.

Which one of the following can be properly inferred from the statements above?
(A) The behavior of organisms with elaborate brain mechanisms is usually not instinctual. -- Cannot be inferred. the behavior could be either of them.
(B) Insect behavior is exclusively instinctual. - CORRECT. Can be inferred since insect brains are do not have large number of neurons.
(C) All organisms with brains larger than insects’ brains are capable of some measure of flexible behavior. -- Cannot be inferred. What if the brain size, although larger than insects', is still not sufficiently large for flexible behavior.
(D) All organisms with large brains are biologically equipped for flexible behavior. - Cannot be inferred. Easy to eliminate
(E) Only organisms with brains of insect size or smaller engage in purely instinctual behavior. Cannot be inferred. Easy to eliminate

Q: what can be inferred from the statements above?
Breakdown statements
- instinct enables organisms to make complex responses
- instinctual behavior nerve cells < noninstinctual (a.k.a. flexible behavior) nerve cells
- flexible behavior must have a large number of neurons
- no insect brain has reached a size capable of providing sufficiently large number of neurons (so basically the insect brain is not capable of flexible behavior)
From our breakdown we can see that the insect brain is not capable of flexible behavior, and is thus entirely instinctual
Answer: B
