In the Trikonasana passage, choose the correct linking word to complete the sentence: "The aim is never to overdo it, but to engage regularly, __________ that you get stronger and more stable over time."

Introduction / Context:
This final blank in the Trikonasana passage concerns a linking word that connects the idea of regular engagement in yoga with the result of becoming stronger and more stable. The correct answer must express purpose or result in a natural, concise way that fits the formal style of the passage.

Given Data / Assumptions:

• The sentence is "The aim is never to overdo it, but to engage regularly, __________ that you get stronger and more stable over time."
• The phrase before the blank gives the method: engage regularly.
• The phrase after the blank describes the result: you get stronger and more stable.
• We need a conjunction that can connect a method with an intended or expected result.

Concept / Approach:
Common English constructions for expressing purpose or result include "so that", "in order that", and "so". In many modern contexts, writers use "so that" or simply "so" before a clause describing the outcome. In the exam sentence, the blank is followed directly by "that", so "so" is the natural word to place there, forming the common phrase "so that you get stronger and more stable over time". The other options "if", "of", and "to" do not create a standard purposeful expression in this position.

Step-by-Step Solution:
Step 1: Identify that the second part of the sentence talks about the result of engaging regularly.Step 2: Recall that "so that" is widely used to introduce a purpose or result clause.Step 3: Recognise that the blank must be filled by "so" to complete the phrase "so that".Step 4: Insert "so" into the sentence: "engage regularly, so that you get stronger and more stable over time."Step 5: Check that the sentence now reads naturally and supports the main message of balanced practice.

Verification / Alternative check:
Try replacing the blank with other options. "Engage regularly, if that you get stronger" is incorrect because "if that" is not a standard combination. "Engage regularly, of that you get stronger" is ungrammatical. "Engage regularly, to that you get stronger" is also wrong. Only "so that" provides a clear cause and effect relationship and fits well with the overall tone of advice in the passage.

Why Other Options Are Wrong:

• Option A "if" introduces a condition, but the phrase "if that you get stronger" is not idiomatic English.
• Option B "of" cannot link two clauses in this way and does not indicate purpose.
• Option D "to" may introduce an infinitive clause, but "to that you get stronger" does not form a correct grammatical structure.

Common Pitfalls:
Some learners may overcomplicate the sentence and search for longer connectors, but the presence of "that" immediately after the blank is a strong clue that "so" is the required word. It helps to memorise common pairs such as "so that" and to notice how they are used in articles, textbooks, and exam passages to express purposeful actions and results.

Final Answer:
The correct linking word is "so", producing the phrase "so that you get stronger and more stable over time".
