The idea
A transition signals a logical relationship between ideas, such as contrast, consequence, addition, or example. Choose the relationship supported by the surrounding statements, rather than a word that merely sounds fluent.
A step-by-step method
- Summarize what each sentence actually states; do not add a cause or comparison that the text does not establish.
- Read both statements without the transition and summarize their relationship.
- Name the relationship precisely: does the second idea contrast with, result from, add to, or illustrate the first?
- Choose the option that communicates that relationship and check the complete sentence.
Worked example
Attempt this original question, then open the reasoning to compare your approach.
In this fictional example, a restoration team planted native trees whose roots held the soil in place. ___ the soil became less vulnerable to erosion. Which transition best completes the text?
- For example,
- However,
- As a result,
- Similarly,
Show answer and reasoning
Answer: C · As a result,
The roots holding the soil in place explain why the soil became less vulnerable to erosion.
“As a result” expresses that consequence.
Why each option works or fails
- The second statement gives a consequence, not a specific example of the first.
- The statements do not contrast.
- Correct: the second statement follows as a result of the first.
- The second statement is not a parallel comparison.
Try a new question
Work independently before opening the explanation. Check what changed and whether the same rule still applies.
In a fictional classroom experiment, students predicted that the heavier ball would reach the ground first. ___ both balls reached the ground at the same time. Which transition best completes the text?
- Therefore,
- However,
- For instance,
- Furthermore,
Show answer and reasoning
Answer: B · However,
The observed outcome differs from the prediction.
“However” signals this contrast; the text does not establish that the prediction caused the outcome.
Why each option works or fails
- The result contrasts with the prediction rather than following from it.
- Correct: the actual outcome contrasts with the prediction.
- The outcome is not an example of the predicted outcome.
- The second statement challenges the prediction rather than simply adding support.
Common mistakes
- A topic shared by two sentences does not determine their logical relationship.
- Do not infer causation solely because one event is mentioned before another.
