Answer 1

there are 8 markers in a set
 nate has 9 markers
 clara has 7 markers
 For nate to have a set, you need:
 9 markers - 1 marker = 8 markers
 For clara to have a set, you need:
 7 markers + 1 marker = 8 markers
 Therefore, nate should give 1 marker to clara so that both have a complete set.
