Odd word out

All of the given options are verbs related to movement. Only "drive," however, relates to the use or movement of a machine, facilitated by a person. All of the other verbs relate directly to human locomotion.

"Ten, " "hundred," "thousand," and "million" all refer to powers of ten. "Fifty" does not.

"Foot," "yard," "mile," and "kilometer" all refer to units of length. "Liter" is not like the others in that it is a unit of capacity.

The acre, the gallon, the pound, and the inch are all units of measurement from the English system of measurement. The kilogram is different in that it is a unit of measurement from the metric system.

"Polyester," "plastic," and "nylon" are all synthetic materials. Thus, the odd word out is "wood," which can be used as building material, but is organic, or naturally occurring.
