Compare common words across the given code sentences to isolate the unique codes for each word instantly.
Step 1: Compare Sentence 1 and Sentence 2
Sentence 1 ('soldier protect country') is coded as 'lu mh na' and Sentence 2 ('entrepreneur prosper country') is coded as 'na ki tu'. The common word between both sentences is 'country', and the common code between both sets is 'na'. Therefore, country = na.
Step 2: Compare Sentence 2 and Sentence 3
Sentence 2 ('entrepreneur prosper country') is coded as 'na ki tu' and Sentence 3 ('soldier entrepreneur vital') is coded as 'mh tu sy'. The common word is 'entrepreneur', and the common code between them is 'tu'. Therefore, entrepreneur = tu.
Step 3: Determine the code for 'vital'
In Sentence 3 ('soldier entrepreneur vital' = 'mh tu sy'), we know entrepreneur = tu and soldier = mh (from Sentence 1 & 3 common word 'soldier' and code 'mh'). Thus, the remaining code 'sy' corresponds to 'vital'.
Step 4: Combine codes for 'country vital'
We found country = na and vital = sy. Hence, the code for 'country vital' is 'na sy' (order of words in the phrase does not restrict the set of codes).
B: 'mh na' is incorrect because 'mh' stands for 'soldier', not 'vital'. C: 'sy ki' is incorrect because 'ki' stands for 'prosper' or 'entrepreneur', not 'country'. D: 'tu na' is incorrect because 'tu' stands for 'entrepreneur', not 'vital'.
Option A is correct because 'country' is coded as 'na' and 'vital' is coded as 'sy', giving the code combination 'na sy'.
