Thanks for explanation, defylogic. If what you said is true, then D should be answer.
The reason I considered those numbers is because I believe that
"Most" means majority (more than 50%), can also mean "all"
"some" means minority (less than 50%)
Where did you read that "some can mean all" ? "Most" can mean all, but if "some" can also mean all, then what is the difference ? I confused now. What book are you referring ?
