Which term means 'Back up with details'?

• A. Explain
• B. Comment
• C. Support
• D. Prove

Answer: (C)

Backing up a claim with evidence and specifics is what this item is about. That idea is captured by the word "support." When you support a statement, you bring in details like data, examples, reasons, or findings to make the claim credible and well-founded. Explain would aim to make something clear, but not necessarily provide evidence. Comment is just an observation or remark, not necessarily tied to supporting evidence. Prove suggests showing something is true beyond doubt, which is stronger than simply providing supporting details in many real-world contexts. Example: a report that supports its conclusion with data from several studies and real-world results.
