Answer 1

Measures of music are usually in groups of four. So musicians usually will start a song with 2, 3, 4, not 1, 2, 3 because the measure starts over after four. Dancers usually group two measures together for dance steps, so they think more in terms of counts to 8. They count out 5, 6, 7, 8 because the next beat is beat 1 in the set of 8.
