If in a certain code, "do la ka" means "what to do", "ma ta do" means "what is this", and "ta re ka" means "this will do", then what is the code used for the word "do"?

1. A

   ma

2. B

   ka

3. C

   la

4. D

   do

Explanation

• The core task is to find the code for the word 'do'.
• Compare the first phrase ('do la ka' = 'what to do') and the third phrase ('ta re ka' = 'this will do').
• The only common English word between 'what to do' and 'this will do' is 'do'.
• The only common code word between 'do la ka' and 'ta re ka' is 'ka'.
• Therefore, the code for 'do' must be 'ka'.

Why Other Options Were Wrong

• Option A: The code 'ma' is incorrect. By comparing 'ma ta do' (what is this) and eliminating the known codes for 'what' (do) and 'this' (ta), 'ma' is left to represent 'is'.
• Option C: The code 'la' is incorrect. In the first phrase, 'do la ka' means 'what to do'. We identified 'do' as 'what' and 'ka' as 'do'. This leaves 'la' as the code for 'to'.
• Option D: The code 'do' is incorrect. While 'do' is a word in the coded phrases, it corresponds to the English word 'what'. This is found by comparing the first two phrases ('do la ka' = 'what to do' and 'ma ta do' = 'what is this'), where the common code is 'do' and the common English word is 'what'.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical reasoning skills, specifically in the area of coding-decoding by substitution as background academic context rather than a clinical decision trigger.
• This type of logical reasoning is not directly related to clinical nursing tasks but is a fundamental component of aptitude tests for nursing school admissions and employment.
• Strong analytical and problem-solving skills are crucial for nurses to interpret patient data, prioritize care, and make sound clinical judgments under pressure.
• What if? If the third phrase was 'ta re la' meaning 'this will to', then comparing it with the first phrase ('do la ka' = 'what to do') would make 'la' the common code and 'to' the common word. In that scenario, the answer for 'do' would be indeterminate without more information.

How to Approach the Question

• First, list all the coded phrases and their English translations clearly.
• Look for pairs of sentences that have one common word in their English translations.
• Identify the corresponding common code word in those two coded phrases. This establishes a direct link.
• In this question, compare 'what to do' and 'this will do'. The common word is 'do'.
• Now look at their codes: 'do la ka' and 'ta re ka'. The common code is 'ka'.
• Conclude that 'do' is coded as 'ka'. Systematically repeat this process to decode other words if necessary and to confirm your answer.
