Alright, let's determine the odd-one out for each set and provide the appropriate reasons:
1. Aeroplane, Bus, Railway train, Ship, Bullock cart
- Odd-one out: Aeroplane
- Reason: The aeroplane is unique because it is the only mode of transport among the options that flies. All the others (Bus, Railway train, Ship, Bullock cart) are surface vehicles.
2. Metre, Kilometre, Yard, Centimetre
- Odd-one out: Yard
- Reason: The yard is distinct from the others because it is not a metric unit. Metres, kilometres, and centimetres are all units in the metric system, whereas the yard is a unit from the imperial system.
3. Handspan, Palm, Foot, Cubit
- Odd-one out: Foot
- Reason: The foot is not traditionally used as an anthropometric measure in the way the others (Handspan, Palm, Cubit) are. Handspan, palm, and cubit are measures based on human body dimensions that date back to ancient times, whereas the foot, though also historically based on human anatomy, has become standardized in modern times and less personal in measurement context.
By carefully considering the characteristics of each item in these sets, we identify the one that doesn't belong and the logical reason for its distinction.
