Research stations do, however, offer a variety of activities and entertainment, 9._________(range) from yoga and keep-fit, to live music and lectures. Loneliness can of course be a problem. But with far too much time 10.______(spend) indoors with the same people, it seems that the main issue for those living inside a research station is finding enough personal space!
