Explanation:

The said query in MongoDB that retrieves all the documents from the listingsAndReviews collection where the property_type is "Apartment" and the number of beds is greater than or equal to 2, along with the listing URL, name, property type, number of beds, and price.

In the find() method it filters the documents where the value of the property_type field is equal to "Apartment" and the $gte filters the documents where the value of the beds field is greater than or equal to 2.

The projection part of the query includes the listing_url, name, property_type, beds, and price fields in the result set.
