Having multiple perceptrons can actually solve the XOR problem satisfactorily: this is because each perceptron can partition off a linear part of the space itself, and they can then combine their results.

• A. true – this works always, and these multiple perceptrons learn to classify even complex problems
• B. false – perceptrons are mathematically incapable of solving linearly inseparable functions, no matter what you do
• C. true – perceptrons can do this but are unable to learn to do it – they have to be explicitly hand-coded
• D. false – just having a single perceptron is enough
