How does charging by conduction compare with charging by induction?

A charged object is needed in conduction but not in induction.
Two neutral objects are needed in conduction but not in induction.
Objects must touch in induction but not in conduction.

Only the last statement is correct.

Brief reasons:
- Charging by conduction requires a charged object to touch a neutral object so charge is transferred; after contact the objects end up with the same sign (not opposite).
- Charging by induction uses a nearby charged object (no direct contact with the object you want to charge) and usually a grounding step; the isolated object can be left with a net charge opposite to the inducer.
So (1) false (induction does need a charged inducer), (2) false (conduction needs one charged and one neutral), (3) false (conduction requires contact; induction does not), (4) true.
