Choices:
1). Not reasonable.
If the plastic spoon were a conductor,
then the bulb would light.
But it didn't.
2). **
3). Not reasonable. If the bottle cap were solid plastic,
then the bulb would not light.
But it did.
4). Not a reasonable conclusion. The toothpick is wood, so the
bulb wouldn't light whether the toothpick is broken or not broken.
When it didn't light, that didn't tell us anything about the health of
the toothpick.
2). ** Reasonable. If the paper clip were solid metal,
then the bulb would light.
But it didn't.
