And when we do see them, typically it would only be one per test. We want to talk about how to spot one, how we should think about reading it and breaking it down. What sort of reasoning structures are likely or unlikely to show up, and what sort of trap answers we might look out for. Here are a few examples of a must be false questions, then, which of the following must be false key words, too obvious, which cannot be true. If the statements above are true, that tells you you're doing some sort of inference question, because they're calling the paragraph statements rather than an argument or reasoning. And instead of asking us what must be true or what's most supported as a typical inference question would, this actually says which can't be true.
