Explanation:

The said query in MongoDB that searches for restaurants that received an "A" grade with a score of 11 on August 11th, 2014. The result documents will only include the "restaurant_id", "name", and "grades" fields.
The search criteria will match documents where the "grades" field contains an array of subdocuments, where at least one subdocument has a "date" field that matches the ISODate "2014-08-11T00:00:00Z".
The same subdocument also has a "grade" field that equals "A" and also has a "score" field that equals 11.
