In the following sentence completion question, choose the most appropriate noun so that the sentence reads: "A metrical thinker should always be moving in a direction which is beneficial and have always been right at every ______."

Introduction / Context:
This question tests your familiarity with idiomatic expressions in English. The sentence describes a "metrical thinker" moving in a beneficial direction and then speaks of being right at every something. The missing noun needs to complete a common phrase that describes consistency at each step or stage of progress.

Given Data / Assumptions:
The incomplete sentence is: "A metrical thinker should always be moving in a direction which is beneficial and have always been right at every ______." We must select the noun that naturally completes this thought. We assume a figurative description of progress and decisions.

Concept / Approach:
The expression "right at every stride" is idiomatic and means being correct or sound at every step or stage. A stride is a long step, and metaphorically it stands for each significant move forward in one's thinking or actions. The other options do not form natural or meaningful collocations with "at every" in this context, whereas "at every stride" is both grammatically correct and semantically appropriate.

Step-by-Step Solution:
Step 1: Recognise that the sentence talks about continuous progress and being right at each step. Step 2: Test each option with the phrase "at every": "at every height", "at every stride", "at every growth", "at every address". Step 3: Notice that "at every stride" is the only phrase that sounds idiomatic and meaningful. Step 4: Understand that "stride" symbolically represents steps or stages in a process. Step 5: Select Option B as the correct word to complete the sentence.

Verification / Alternative check:
Read the complete sentence: "A metrical thinker should always be moving in a direction which is beneficial and have always been right at every stride." This suggests that such a thinker is correct at each important step in their reasoning or development. In contrast, "at every height" sounds awkward, as does "at every growth" and "at every address". None of those collocations is standard in English for describing ongoing correctness at each stage, confirming that "stride" is the right choice.

Why Other Options Are Wrong:
Option A, "height", is usually used with prepositions like "at a great height" or "at the height of", not "at every height" in this type of sentence. Option C, "growth", refers to development or increase and does not form a natural phrase "at every growth" here. Option D, "address", typically refers to a speech or location and would not complete the expression meaningfully. None of these words carries the idiomatic sense of repeated steps in a journey of thought or action.

Common Pitfalls:
A common mistake is to overanalyse the meaning of "metrical thinker" and get distracted from the collocation needed at the end of the sentence. Another pitfall is to imagine new phrases like "at every height" that are not actually used in standard English. To succeed in such questions, it helps to read widely and internalise common fixed expressions. When in doubt, choose the word that forms a familiar and meaningful phrase rather than inventing a new combination.

Final Answer:
The correct word to complete the sentence is "stride".
