A developer is using a language model to summarize a complex scientific article. They decide to use a technique where they generate three summaries using three different prompts and then combine the results.

Approach A uses three very similar prompts:

1. 'Summarize the following text.'
2. 'Provide a summary of the article below.'
3. 'Create a short summary of this document.'

Approach B uses three more distinct prompts:

1. 'Summarize the key findings of this article for a scientific audience.'
2. 'Explain the main argument of this text as you would to a high school student.'
3. 'Extract the three most important conclusions from the following article as bullet points.'

Which approach is likely to yield a better, more comprehensive final summary, and why? Explain the core principle that justifies your choice.
