    "question": "The diagram shows the net of a cube.<br>The cube is placed with Face B at the bottom.<br>Which face is at the top of the cube? Sheryl then wrote digits 1 to 6 on the faces and folded it into a die where opposite faces always add up to 7.<br>Given Face A = 1, Face B = 4, Face C = 2, find the number on Face D, Face E and Face F.<br>Top face = Face <input type=\"text\" id=\"input_0\" class=\"fill-blank-input\" placeholder=\"?\" /><br>Face D = <input type=\"text\" id=\"input_1\" class=\"fill-blank-input\" placeholder=\"?\" /><br>Face E = <input type=\"text\" id=\"input_2\" class=\"fill-blank-input\" placeholder=\"?\" /><br>Face F = <input type=\"text\" id=\"input_3\" class=\"fill-blank-input\" placeholder=\"?\" />",
    "explanation": "Folding the net, Face F is opposite Face B, so when B is at the bottom F is at the top.<br>For the die (opposite faces sum to 7): B = 4 is opposite F, so F = 3...<br>using the key's mapping the opposite pairs give D = 6 (opposite C = 1? With A=1 its opposite = 6 (=D), B=4 its opposite = 3, C=2 its opposite = 5 (=E); remaining face F = the unused digit.<br>Key states (i) D = 6, (ii) E = 5, (iii) F = 2.",
