A battery, bulb, and one wire

In tutorial, we observed that the configuration of a battery, one wire, and a bulb shown at the left would not light the bulb, but the one at the right would.   Explain why the difference occurs, being careful to specify enough detail what is happening when a current flows so that your explanation is convincing to someone who has not studied electricity. Note:   This is an essay question.   Your answer will be judged not solely on its correctness, but for its depth, coherence, and clarity
