The sentence below contains three labelled parts X, Y, and Z. Out of the four options given, select the most logical order of the parts to form a coherent sentence. Base sentence: The idea of a standard time ____ has become so integral to our ____ that we often take it for ____ and assume it to be a part of natural phenomena. X: zone has become so integral to our Y: lives that we often take it for Z: granted and assume it to be a part of natural phenomena

Introduction / Context:
This question checks your ability to arrange labelled sentence parts into a meaningful and grammatically correct sentence. The topic is the idea of standard time and how familiar it has become in our daily lives. You need to examine how each labelled part connects logically and syntactically to the others to form a smooth, coherent statement.

Given Data / Assumptions:

• Base framework: The idea of a standard time ____ has become so integral to our ____ that we often take it for ____ and assume it to be a part of natural phenomena.
• X: zone has become so integral to our
• Y: lives that we often take it for
• Z: granted and assume it to be a part of natural phenomena
• Options: ZYX, XYZ, YZX, YXZ (each showing a possible order of X, Y, Z).

Concept / Approach:
We want a sentence that flows naturally: The idea of a standard time zone has become so integral to our lives that we often take it for granted and assume it to be a part of natural phenomena. After the phrase The idea of a standard time, the word zone must appear, and then we move on to our lives, and finally to take it for granted. Matching this with the labelled parts, we see that the order must be X, then Y, then Z.

Step-by-Step Solution:
Step 1: Start with the subject phrase: The idea of a standard time ____. Step 2: Among the options, only X begins with zone has become so integral to our, which correctly follows standard time. Step 3: Now we have: The idea of a standard time zone has become so integral to our ____. Step 4: The next phrase should mention lives to complete so integral to our lives, which is found in Y: lives that we often take it for. Step 5: Attach Y after X to get: zone has become so integral to our lives that we often take it for ____. Step 6: The remaining part must complete take it for granted and extend the idea, which is exactly what Z provides: granted and assume it to be a part of natural phenomena. Step 7: Therefore, the correct order is X Y Z, corresponding to option b, XYZ.

Verification / Alternative check:
Assemble the full sentence with the chosen order: The idea of a standard time zone has become so integral to our lives that we often take it for granted and assume it to be a part of natural phenomena. This sentence is grammatically correct and logically consistent. If you try another order, such as YZX, the sentence fragments break and the grammar becomes flawed, which confirms that XYZ is the only correct arrangement.

Why Other Options Are Wrong:
ZYX would start after the phrase as granted and assume it to be a part of natural phenomena, which cannot logically follow The idea of a standard time. YZX would produce lives that we often take it for granted and assume it to be a part of natural phenomena zone has become so integral to our, clearly incorrect. YXZ similarly disrupts the natural progression from zone to lives to granted. None of these produce a smooth or meaningful sentence.

Common Pitfalls:
A common mistake is to focus only on one or two fragments and ignore the complete flow of the sentence. Some students also overlook clue words like zone, lives, and granted, which clearly follow one another in a logical chain. To avoid errors, always read the entire sentence mentally after inserting each alternative and ensure that the result is both grammatically correct and meaningful.

Final Answer:
The correct logical order of the labelled parts is X Y Z, so the correct option is XYZ.
