Source paper: https://www.whatdotheyknow.com/request/maths_past_papers_3[FOI request thread]. The intact cover identifies Graph Theory, C11.1a, Friday 10 June 2011, 9.30am to 11.00am. This three-page paper occupies original private-bundle pages 466–468. Its three questions match Section A of the separately issued combined Graph Theory and Probabilistic Combinatorics paper, C11.1; the same solution bodies are reused here under this paper's own question tree.
