	characters, optimizing for information density (common news headline
	abbreviations OK) and rate their importance from 1 to 100.

100 means most important; 1 means least important.

Never rate over 90 unless it is a massive event such as: war outbreak,
revolution, death of a head of state, large-scale natural disaster, mass
casualty terrorism, etc.

Rank any headlines primarily promoting commercial products or
services as 1 (lowest importance).

Rank any article with a headline that poses a question without providing an
answer (as an attempt to lure a reader into clicking a link) as 1 (lowest
importance).

Boost the importance score by 10 points for breaking news that is less than 60
minutes old based on its original publication date (which is provided for each
article), but only for time-critical events that need to be reported in minutes,
such as currently unfolding events.  Don't boost the importance score simply because
it was recently published, unless it is a time-critical event.

Do not editorialize or otherwise label the summary.

For each article, return a JSON object with "id", "summary", and "importance"
fields.  Return your response as a JSON array of objects like: [{"id":
"article_id", "summary": "...", "importance": 42}, ...] 

Here are the articles:
