when was the last date antarctica was free of ice?
about 34 million years ago
antarctica is the coldest of earth's continents. it used to be ice-free until about 34 million years ago, when it became covered with ice. the coldest natural air temperature ever recorded on earth was at the russian vostok station in antarctica on 21 july 1983. for comparison, this is 10.7 °c (20 °f) colder than subliming dry ice at one atmosphere of partial pressure, but since co only makes up 0.039% of air, temperatures of less than would be needed to produce dry ice snow in antarctica. a lower air temperature of was recorded in 2010 by satellite—however, it may be influenced by ground temperatures and was not recorded at a height of above the surface as required for the official air temperature records. antarctica is a frozen desert with little precipitation; the south pole receives less than per year, on average. temperatures reach a minimum of between and in the interior in winter and reach a maximum of between and near the coast in summer. sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.

"here's the answer" was recorded at the rca victor studio in nashville, tennessee, united states in three sessions. the first session took place may 13, 1960, followed by a session october 11, and then ending in december of that year. like davis' previous release, she harmonized with herself on the recordings in order to give her voice and the production a fuller sound. the album consisted of cover versions of major hit singles by country artists on the rca victor label, followed by davis' answer song to the hit. it included the original versions of hits by artists such as jim reeves' "he'll have to go", floyd cramer's "last date", and hank locklin's "please help me, i'm falling". in response, davis sings the answer songs; "he'll have to stay", "my last date (with you)", and "(i can't help you) i'm falling too". richie unterberger of "allmusic" called the concept behind the album to be "hokey". unterberger explained that half of the album wasn't "davis at all", but instead the original versions of the song by the original artists are included. unterberger gave the release only two out of five stars, stating, "it gets really ridiculous when davis sings an answer song ("my last date") to floyd cramer's instrumental hit "last date." davis' songs are okay mainstream country/pop; a couple of them ("(i can't help you) i'm falling too" and "my last date") were even top 40 pop hits. but alternating her tracks bang-bang with hits by various other male country stars makes for a rather herky-jerky listening experience."
