| 1. | The multiple valid parse trees are computed simultaneously, without backtracking.
|
| 2. | The resulting of multiple parse trees per grammar denotes grammar ambiguity.
|
| 3. | Only the shaded lower-left corner of the parse tree exists.
|
| 4. | None of the parse tree nodes numbered 7 and above exist yet.
|
| 5. | Parse tree ambiguity concerns the existence of multiple parse trees per sequence.
|
| 6. | Parse tree ambiguity concerns the existence of multiple parse trees per sequence.
|
| 7. | It is best to think of them in terms of parse trees.
|
| 8. | None of the parse tree nodes numbered 8 and above exist yet.
|
| 9. | They are always at the bottom bushy end of the parse tree.
|
