$geoNear matching nearest array

I have document in record collection Mongodb (3.4) like below :-

    { 
      "_id" : ObjectId("592d0c78555a7436b0883960"), 
      "userid" : 7, 
       "addresses" : [
        {
            "apporx" : 50.0, 
            "loc" : [
                -73.98137109999999, 
                40.7476039
            ]
        }, 
        {
            "apporx" : 15.0, 
            "loc" : [
                -73.982002, 
                40.74767
            ]          
        }, 
        {
            "apporx" :10.0, 
            "loc" : [
                -73.9819567, 
                40.7471609
            ]
        }
     ]
    }
`

I created index on this collection using below query :- 
`db.records.createIndex({'addresses.loc':1})`

when i execute my below query :-
`db.records.aggregate( 
      {$geoNear : {
        near : [ -73.9815103, 40.7475731 ],
        distanceField: "distance" 
    }});

this result gives me distance field.now can you explain me in my document which address array in this multiple elements exists. how can i determine for which element this result true?

Another question :- if i make condition on "addresses.apporx" like greater then or equal then is there any way to find location of this condition?
