The question below consists of a set of labelled sentence fragments. Out of the four options given, select the most logical order of the labels to form a coherent sentence: "They had seen enough of the X-them to come a step farther Y-desert already, and no number Z-of knives would have tempted". Which sequence of labels correctly completes this sentence?

Introduction / Context:
This question tests your skill in sentence rearrangement and logical ordering of labelled fragments. You are given parts of a sentence marked X, Y and Z, and must select the order that produces a grammatically correct and meaningful sentence. Such questions are common in English sections because they test both grammar sense and reading logic. The sentence here describes people who have already seen enough of a desert and refuse to go further even if offered knives.

Given Data / Assumptions:

• The base sentence framework is: They had seen enough of the X-them to come a step farther Y-desert already, and no number Z-of knives would have tempted.
• Thus, X belongs before them to come a step farther.
• Y belongs before desert already.
• Z belongs before of knives would have tempted.
• The label fragments are:
  • X: them to come a step farther
  • Y: desert already, and no number
  • Z: of knives would have tempted

Concept / Approach:
To build the correct sentence, first reconstruct the intended meaning in normal English, then match each fragment to its proper position. We want a sentence that reads smoothly and logically, such as They had seen enough of the desert already, and no number of knives would have tempted them to come a step farther. Once you have this target sentence in mind, you can map each label to the appropriate gap and derive the correct order Y Z X for the labels.

Step-by-Step Solution:
Step 1: Imagine a natural sentence: They had seen enough of the desert already, and no number of knives would have tempted them to come a step farther. Step 2: Identify where Y should go. The phrase desert already, and no number fits after of the, giving of the desert already, and no number. Step 3: Identify where Z should go. The phrase of knives would have tempted naturally follows no number, producing no number of knives would have tempted. Step 4: Identify where X should go. The phrase them to come a step farther follows tempted, giving would have tempted them to come a step farther. Step 5: Putting this together gives the sequence of labels Y, Z, X. Therefore, the correct option is YZX.

Verification / Alternative check:
Test each option by placing the labels into the skeleton. For option YXZ, you would get of the desert already, and no number them to come a step farther of knives would have tempted, which is ungrammatical. For option XZY, you would get of the them to come a step farther desert already, and no number of knives would have tempted, which also fails. For option XYZ, the order of ideas is distorted. Only YZX yields the smooth, meaningful sentence They had seen enough of the desert already, and no number of knives would have tempted them to come a step farther, which matches standard English usage.

Why Other Options Are Wrong:
Option YXZ incorrectly places them to come a step farther immediately after no number, breaking the close pairing of no number and of knives. Option XZY begins with them to come a step farther in a position where the noun desert should appear, resulting in confusion. Option XYZ attaches them to the phrase no number, instead of to tempted, disrupting both grammar and meaning. None of these orders produce a coherent sentence about people refusing to go further into the desert in spite of offers of knives.

Common Pitfalls:
A typical mistake is to rely only on local grammar, joining fragments that seem to fit together without considering the entire sentence. Another pitfall is to ignore meaning and focus solely on mechanical matching of fragments. For success, always first form a clear idea of what the complete sentence should mean. Once the meaning is in your mind, it becomes much easier to place each fragment in its logical position. Practising this mental reconstruction on similar questions will strengthen your performance on rearrangement items.

Final Answer:
The most logical and grammatically correct order of the labels is YZX, which yields the sentence They had seen enough of the desert already, and no number of knives would have tempted them to come a step farther.
