They made four model sailboats (W, X, Y and Z) using the design shown. The sailboats were the same except for the positions of their masts.

7 © UNSW Global Pty Limited QUESTION KEY KEY REASONING LEVEL OF DIFFICULTY 1 C The upper part of the human digestive tract is made up of the mouth, oesophagus and stomach. The gall bladder, large intestine and small intestine make up the lower part of the digestive tract, hence, A, B and D are wrong. The oesophagus is between the mouth and the stomach. Easy 2 D The thickest syrup would be the slowest to move down a slope. This means that the thickest syrup would travel the least distance in one minute down the same slope. From the column (bar) graph, the blue syrup travelled the small - est distance, so the thickest syrup is the blue. The least thick (runniest) syrup would travel the fastest down the slope, and so in one minute would travel the greatest dis - tance down the slope, so C (green) is incorrect. Medium 3 D The ticks in the table show some of the weather condi - tions and the type of bird visiting the playground during one week. The cockatoos visited when it was hot and calm, and when it was cold and calm, but not when it was windy. Therefore they were most likely to visit when it was calm. Medium 4 D The speed of the boats is determined by the distance they travelled in 5 minutes, so we must use the second (blue) graph. The slowest boat travelled the smallest distance in 5 minutes, so the correct answer is D. Medium 5 A To test the effect of the position of the mast on the boat speed we must change the position of the mast, so answer C is wrong. For the test to be fair all other things must be kept the same, so answers B and D are wrong. Medium LEGEND Level of difficulty refers to the expected level of difficulty for the question. Easy more than 70% of the candidates will choose the correct option. Medium more than 50–70% of the candidates will choose the correct option. Medium/Hard more than 30–50% of the candidates will choose the correct option. Hard Less than 30% of the candidates will choose the correct option.
