{"answer_type":"Numerical","is_multiple_answer":false,"language":"English","question":"Find the smallest positive integer $k$ for which there exist a colouring of the positive integers $\\mathbb{Z}_{>0}$ with $k$ colours and a function $f: \\mathbb{Z}_{>0} \\rightarrow \\mathbb{Z}_{>0}$ with the following two properties:\n\n(i) For all positive integers $m, n$ of the same colour, $f(m+n)=f(m)+f(n)$.\n\n(ii) There are positive integers $m, n$ such that $f(m+n) \\neq f(m)+f(n)$.\n\nIn a colouring of $\\mathbb{Z}_{>0}$ with $k$ colours, every integer is coloured in exactly one of the $k$ colours. In both (i) and (ii) the positive integers $m, n$ are not necessarily different.","question_type":"Open-ended","subject":"Math"}
