Answer 1

1. NO & NO
2. YES & YES
3. NO
4. YES & NO
5. NO & YES*

*Safari supports run-in when it occurs before an element with display: inline. This should not happen. So technically, it is supported, but has issues.

Answer 2

According to quirksmode:

• IE8 (as IE8) and Opera 9.6.2 and 10 will render it correctly;
• Safari 3/4, Chrome 1+ and Konqueror render it incorrectly; and
• other browsers do not render it at all.
