Cause and Effect in Reading

Much of nonfiction is about why things happen. When you can trace the link from a cause to its effect, you understand not just what occurred but the reason behind it.

Cause and effect is a text structure in which one event or condition (the cause) brings about another (the effect). Writers signal it with words like “because,” “since,” “led to,” “as a result,” and “therefore.” Recognizing this pattern lets you answer “why” questions and follow an author’s reasoning.

Spotting Causes and Effects

A cause is the reason something happens; an effect is the result. In the sentence “Because the road flooded, the school closed,” the flood is the cause and the closing is the effect. Signal words make the link visible: “because,” “since,” and “due to” usually point to a cause, while “so,” “as a result,” and “consequently” point to an effect. Not every cause-and-effect passage uses these words, though, so sometimes you must ask, “Did this happen because of that?” One cause can have several effects, and one effect can have several causes. A single storm might close roads, cancel flights, and knock out power — three effects from one cause.

Avoiding Common Traps

The biggest mistake is assuming that because one event came before another, the first caused the second. Order alone does not prove cause. If a passage says sales rose after a new sign went up, the sign might have helped — or something else might explain the rise. Look for the text to actually state or strongly suggest the connection before you treat it as cause and effect. Also, keep cause and effect straight in your mind; questions may try to swap them. If “heavy rain caused flooding,” then flooding did not cause the rain. Reading the signal words carefully and asking “which came first, and did it truly bring about the other” keeps your answers sound.

A Routine for Cause and Effect

1. Ask “why did this happen?” to find the cause.
2. Watch for signals like “because,” “led to,” and “as a result.”
3. Keep cause and effect in the right order.
4. Do not assume order alone proves cause.

Practice

1. What is cause and effect?
2. In “Because the road flooded, the school closed,” what is the effect?
3. Name two words that signal a cause.
4. Can one cause have several effects?
5. Why is order alone not proof of cause?
6. If rain caused flooding, did flooding cause the rain?

Answers

1. A structure where one event brings about another.
2. The school closing.
3. Any two: because, since, due to.
4. Yes — one cause can lead to several effects.
5. Something else might explain the second event.
6. No.
