someone or ereryone?

[Vaok]

1. I made so many changes in my composition that only I could read it. To _____ else, it was hard to make out.

A. none B. everyone C. someone

2.My grandma still treats me like a child.She can,t imagine ___grown up.

A. my B. mine C. myself D. me

Could anybody tell me which is proper and why?

[Daemon99]

1. The answer is B. Because only you could make out what was written in the composition. And everyone else had a problem understanding it. (everyone else = everyone excluding you)

2. The answer is D.
But the sentence looks a little strange to me. "She can't imagine me as a grown-up" looks more natural to me.

May be the gurus would be kind enough to shed more light on it.
