Explanation:
The said query in MongoDB that retrieves all the documents with listing_url, name, property_type, bed, price, and guests_included fields from the listingsAndReviews collection that have a maximum of 5 guests included in the price.
The $match stage filters the documents where the guests_included field has a value less than or equal to 5.
The $project stage includes listing_url, name, property_type, bed, price, and guests_included, so we set their values to 1.
