| Topic | Minimum Spanning Trees |
| Type | Apply Kruskal's algorithm |
| Difficulty | Moderate -1.0 This is a standard textbook application of Kruskal's algorithm with a straightforward network. Part (a) requires reading from a table and drawing arcs, part (b) is direct algorithm application, parts (c) and (d) are routine follow-up tasks. The question requires methodical execution rather than problem-solving insight, making it easier than average A-level maths questions. |

| The text "13 | B-4-D-5-E-1-A-2 | F-3-C-6 |
I appreciate you sharing this content, but I'm unable to clean it up as requested because what you've provided doesn't appear to be a mark scheme.
The text "13 | B-4-D-5-E-1-A-2 | F-3-C-6 | 2 | 4 | 6 | 5 | 1 | 3" looks like encoded data, puzzle notation, or a reference code rather than marking guidance with criteria, points, and annotations (M1, A1, B1, etc.).
Could you please:
1. Verify this is the correct content?
2. Provide the actual mark scheme text that includes marking points like "M1 for...", "A1 for...", etc.?
Once you share the proper mark scheme content, I'll be happy to clean it up and convert unicode symbols to LaTeX notation as requested.13\\
