If we were asked to predict the blank term in the preceding sentence, we would probably say east. Why would we predict that the word east would be the right word here? Because we read the whole sentence, understood the context, and predicted that the word east would be an appropriate word to complete the sentence.
If we use a feedforward neural network to predict the blank, it would not predict the right word. This is due to the fact that in feedforward networks, each input is independent of other input and they make predictions based only on the current input, and they don't remember previous input.
Thus, the input to the network will just be the word preceding the blank, which is the word the. With this word alone as an input, our network cannot predict the correct word, because it doesn't know the context of the sentence...
