I'm looking for someone to create 100 original multiple choice questions (they can't be copied from anywhere -- you must think of them all by yourself) for Cognos. Some questions should have actual code snippets. The questions should be of varying difficulty (Medium - 30, Hard - 30). Additionally, you'll need to provide a URL source and page title that proves that the correct answer is indeed accurate. You also need to identify a topic that the question belongs to (you can make up whatever topics you want, the topics are a way to organize the questions. Some questions can include code snippets or images.
