In a certain code language, 'birds fly high' is coded as 'to zi ri' and 'clouds fly high' is coded as 'ri zi ne'. How is 'fly' coded in that language?

The correct option is zi or ri.

Step-by-step Explanation:

Step 1: Write down the given statements and their corresponding codes.
Statement 1: 'birds fly high' = 'to zi ri'
Statement 2: 'clouds fly high' = 'ri zi ne'

Step 2: Compare the two statements to find common elements.
When we compare Statement 1 and Statement 2, we notice the following:
- The words common to both statements are 'fly' and 'high'.
- The code words common to both statements are 'zi' and 'ri'.

Step 3: Deduce the code for 'fly'.
Since the pair of common words {'fly', 'high'} corresponds to the pair of common codes {'zi', 'ri'}, we know that:
'fly' and 'high' are coded as 'zi' and 'ri' in no specific order.
The remaining unique words and codes can also be identified:
- 'birds' corresponds to 'to'
- 'clouds' corresponds to 'ne'

Because there are no further statements provided to distinguish 'fly' from 'high', we cannot determine with certainty which of the two codes belongs specifically to 'fly'. Therefore, 'fly' can be coded as either zi or ri.
