When the ends of two wires, from a circuit containing a battery and a lightbulb, are placed into a beaker containing an aqueous solution the light bulb glows brightly. From this observation, you can conclude the solution is probably —

• a concentrated but weak base

• a strong acid

• a nonelectrolyte

• a weak acid
