An elementary school class tried feeding apples, broccoli, cucumber, hay, and lettuce to a guinea pig and a rabbit. When given any two of these foods, each animal clearly and consistently preferred one over the other:
- The guinea pig preferred apples to broccoli, but the rabbit showed the opposite preference.
- The rabbit preferred cucumbers to hay, but the guinea pig showed the opposite preference.
- The guinea pig preferred cucumbers to the rabbit's favourite of the five foods
- The rabbit preferred lettuce to the guinea pig's favourite of the five foods
Base on the information, select for
Guinea pig's favourite a pair of foods such that either might have been the guinea pig's favourite and select
Rabbit's favourite a pair of foods such that either might have been the rabbit's favourite. Make once two selections, one in each column.
Just write down the preferences and you should get the answer.
Guinea pig:
The guinea pig preferred apples to broccoli. So broccoli is surely not the main preference.
So option 2 and option 3 are out. The rabbit preferred cucumbers to hay, but the guinea pig showed the opposite preference.
Clearly cucumber is not but hay can be the favourite.
So, option 4 too is out. The rabbit preferred lettuce to the guinea pig's favourite of the five foods
Again, this means lettuce is not the favourite
