Content factors:
- Does it reference events, people, or topics that are relevant to news since July 2023?
- Does it discuss current affairs, politics, culture, technology, or other topics typically covered in news?
- Is the content substantive enough to be newsworthy?

Style factors:
- Does it use the formal, concise language typical of NYT headlines?
- Is it formatted like a headline (not a full sentence or paragraph)?
- Does it avoid slang, excessive punctuation, or overly casual language?

Even if only some aspects match (e.g., content is relevant but style is off, or vice versa), give partial credit.
- Score 0-3: Not at all like a NYT headline in content or style
- Score 4-6: Has some elements that resemble a NYT headline
