In an artificial technical code language:
• 'soil test is good' is coded as 'pe da ro ka'
• 'good crop yield high' is coded as 'ka te no si'
• 'is crop yield high' is coded as 'ro te no si'
• 'soil fertility is high' is coded as 'pe zo ro si'
What is the code for the word 'crop'?
Options:
(A) te
(B) no
(C) Cannot be uniquely determined between 'te' and 'no'
(D) ka
Answer Key:
C
Step-by-Step Solution & Explanation
1. Comparing sentence 1 ('pe da ro ka') and sentence 2 ('ka te no si'), the common word is 'good', hence 'ka' = 'good'.
2. In sentence 4 ('pe zo ro si') and sentence 1, common words are 'soil' and 'is', with codes 'pe' and 'ro'. Comparing with sentence 3 ('ro te no si'), common word is 'is', so 'ro' = 'is', which leaves 'pe' = 'soil'.
3. From sentence 4, since 'ro' = 'is', 'si' = 'high'.
4. Now examining sentence 2 and 3: both contain words 'crop' and 'yield' and codes 'te' and 'no'. No additional premise isolates 'crop' from 'yield'. Therefore, the exact code for 'crop' cannot be uniquely determined between 'te' and 'no'.
