To determine the best answer for how paragraphs 8-9 contribute to the development of ideas in the article, let's analyze the options provided:
A. Supporting the idea that magpies are nonviolent birds. - This option could be relevant if the paragraphs discuss the peaceful nature of magpies, but without the specific content, it’s hard to confirm.
B. Describing a situation in which a magpie was friendly toward a person. - If the paragraphs contain a narrative or an example of a friendly interaction between a magpie and a person, this would help illustrate magpies' social nature and ability to form bonds with humans.
C. Providing instructions for how a person can obtain a magpie's trust. - If the paragraphs include practical advice or methods for building a relationship with a magpie, this would clearly align with this option.
D. Comparing magpies' behavior to the behavior of other birds. - If the paragraphs provide comparisons to other birds, it would contribute to understanding magpies' unique traits in a broader context.
Based on the analysis, if the paragraphs focus on an anecdote about a specific interaction showcasing a magpie's friendliness, then the best answer would likely be B. If the paragraphs focus on gaining a magpie's trust or trust-building techniques, then the best choice would be C. Without the exact text, it’s difficult to definitively choose, but make sure to refer back to the content for the most accurate understanding.
