Question

which transitional words or phrases should be used to clarify the relationships between the ideas?
○ but; however
○ yet; as a result
○ however; in addition
○ for example; therefore

Explanation:

To solve this, we analyze the relationships each pair of transitional words/phrases conveys.

• "But" and "However" both indicate contrast, so they can be used to clarify relationships between ideas with a contrasting nature.
• "Yet" is contrast, but "As a result" is cause - effect, so they don't match well.
• "However" is contrast and "In addition" is addition, different relationship types.
• "For example" is illustration and "Therefore" is cause - effect, not a consistent relationship type.

Answer:

A. But; However
