Author's Assumption
Each passage presents a short argument: some evidence, then a conclusion. The right answer is the unstated premise the argument quietly depends on — the missing idea that must be true for the conclusion to hold. It is not extra support; it is something the author has simply taken for granted.
How to work: find the conclusion, then the gap between the evidence and that conclusion. The assumption is what bridges that gap. A reliable check is the negation test: negate a choice — if the argument falls apart, that choice was a necessary assumption. Watch for traps that merely restate a premise, add support the argument doesn't need, or are simply out of scope. Answer all ten, then press Submit for your score and full explanations.
