Organising given information before new information (the "given–new" principle) makes a text much easier to follow, so Version B’s clearer ordering is the key reason it was easier to understand.

1) Relevant knowledge points and concepts
- Given–new principle: readers comprehend text more easily when known/familiar information (given) precedes unfamiliar/new information, because it creates a coherent link and reduces processing load.  
- Cohesion and topic sentences: clear signposting and logical progression (topic sentence → supporting detail) improves readability.  
- Cognitive load: poor sequencing or sudden introduction of concepts increases the memory burden on readers.

2) Step-by-step reasoning
- Step 1: Identify how comprehension depends on information flow. When a sentence or paragraph begins with familiar context, the reader can anchor new facts to that context.  
- Step 2: Compare the two versions in terms of ordering: Version A likely introduced new concepts without first establishing context; Version B arranged sentences so that each new point followed familiar material.  
- Step 3: Conclude that this ordering reduces confusion and makes relationships between ideas explicit, improving understanding.

3) Intermediate steps / no numerical calculations
- No numeric calculation is required. The intermediate logical steps are: observe ordering → apply given–new principle → predict comprehension outcome → confirm Version B is easier.

4) Why the correct answer is correct
- Option (a) precisely names the mechanism: Version B organised given and new information more effectively, creating clearer links between prior context and novel points. That directly explains improved comprehension.

5) Why the other options are incorrect
- (b) Simpler vocabulary: Possible but not asserted; the chapter emphasised structural reordering rather than word-level simplification.  
- (c) Shorter: Shortness alone does not guarantee clarity; a short but poorly organised text can still be confusing.  
- (d) More examples: Examples help, but the chapter highlighted the placement of information (given → new) as the principal improvement, not a change in number of examples.

Conclusion: Because Version B applied the given–new ordering and improved cohesion, it was easier to understand. This confirms answer (a).
