Section A consists of 15 multiple-choice questions. For eac h question, there are four possible answers A, B, C and D. Choose the one you consider correct and record your choice in soft pencil on the separate Optical Mark Sheet. You are advised to attempt Section A first. The Opti cal Mark Sheets will be collected after the first 30 minutes. Section B consists of 5 structured questions. You are to write your answers in the spaces provided. Section C consists of 1 long structured question and 1 data analysis question. You are to write your answers in the spaces provided. Attempt all questions in Sections A, B and C. There are 9 printed pages, inclusive of the cover page and data & formulae page, in this booklet.
