Drawing Simple Logical Conclusions

A supported conclusion on the Reading test is one logical step beyond what the passage states, built only from facts actually given. It is not stated outright, but it is forced by the details, not guessed from outside knowledge.

Think of every stated fact as a solid box. The passage hands you a set of these boxes and nothing else. Your job is to stack one dotted box on top, a claim the solid boxes make almost unavoidable even though no sentence says it. If a woman rides a bus to the last stop and back every day with coins counted out and a bag she never fills, the solid boxes are: same fare either way, round trip, driver now saves her seat. The one dotted box those boxes support is that she rides for the ride, not to get anywhere. Add a second dotted box, say she is lonely or grieving, and you have left the structure standing on air.

The test rewards the first dotted box and punishes the second. Wrong answers are usually not stupid, they are interesting: they use the passage as a springboard into psychology or backstory the text never built. The right answer is often the flatter, almost boring claim that every solid box points straight at, nothing more. That flatness is a clue, not a flaw.

This sits right next to paraphrase and detail questions in the same unit because the skill is the same muscle used more carefully. A detail question asks you to restate a solid box accurately. A conclusion question asks you to add exactly one dotted box on top of several solid ones. Both fail the same way when a reader imports outside knowledge or personal reaction instead of staying inside what the boxes actually permit.

Key terms

Stated fact
A detail the passage directly gives, treated as a solid, fixed box you can build on.
Supported conclusion
A claim not stated outright but made necessary by combining the passage's stated facts.
Overreach
A conclusion that needs an extra assumption beyond the stated facts, two steps past the evidence instead of one.
Provisional result
A finding treated as not yet fully confirmed, often pending independent verification.

  3. Common mistakeWhy isn't the most interesting conclusion usually the one the ACT is after?
  4. Going furtherWhat separates a conclusion one step past the evidence from an overreach two steps past it?

Informational passage: When the signal first appeared in her data, Okonjo ran the experiment again. Then she ran it 16 more times, changing the detector each time and asking a colleague to record the results without knowing which run was which. The effect held. In the paper she published in 2012 she gave it two paragraphs near the end and spent the rest on the apparatus, and she wrote that a result of this size in a field this noisy deserves to be treated as provisional until someone outside her laboratory has seen it. The passage most strongly supports which conclusion about Okonjo?
