Word ladders (1): 10 questions

Questions 1 to 5 and 6-10 are separate groups. Each group gives a clue to a two-word phrase, or eight letter word made of two distinct parts, where each word or part has four letters (e.g. chat show, download, reindeer etc.). The five answers (or part thereof) in each group transform one word into the other, changing one letter at a time. For example, the answers in one group of questions might be; Hell – Hill – Fill – File – Fire for the two-word phrase hell-fire.
