for proving C2 false take girl circle and make ballet dancer inside girl circle so there are some girls which are definitely not  ballet dancer

Answer 1

Both conclusion follows

If we make Venn diagram, All girls are beautiful- represents all set of girls

All ballet dancers are girls. is a part of of that set or can be full set of girls too

So, All set of ballet dancers are girls, and all girls are beautiful conclude " All ballet dancers are beautiful. "

And as a part of girl is ballet dancer , so it also follows " Some girls are ballet dancers. "
