Choose a logical transition
Name the relationship between ideas before selecting a connector.
Common relationships
“However” signals contrast; “therefore” signals a result; “for example” introduces an illustration; “similarly” indicates likeness.
Logic and punctuation are separate
A logical transition still needs correct sentence boundaries. “However” is not a coordinating conjunction. Use “A; however, B” or “A. However, B” when A and B are complete clauses.
A transition states a relationship already present
The connector should express the logic between ideas; it cannot create a causal link that the sentences do not support. Ask whether the second sentence adds a similar point, contrasts with the first, gives an example, states a result, or clarifies what the first means.
Read enough context to find the real connection
A blank at the start of a sentence often depends on the previous sentence, but the connection may involve a broader passage idea. Do not choose by the topic word immediately before the blank. After selecting the relationship, reread to check both meaning and sentence boundaries.
Worked example
“The archive added searchable topic labels. ____, researchers located documents more quickly.”
- Adding labels causes the improved search.
- Use a result transition rather than a contrast or example.
Consequently, researchers located documents more quickly.
Watch for this: A transition can sound smooth while expressing the wrong relationship.
Check your understanding
The route is short and flat. ____, its final hill is steep. Which transition best fits?
- Therefore
- Similarly
- However
- For instance
Show answer and explanation
Answer: C. “However” signals the contrast between the generally easy route and its difficult final hill.
Rhetorical Synthesis
Use notes to meet a rhetorical goal
Select relevant notes and combine them for the task the question names.
Read the goal first
The task may ask for a similarity, difference, introduction, emphasis, or generalization. The best answer is the one that achieves that goal accurately.
Select rather than summarize everything
A successful sentence does not need to include every note. Exclude facts that distract from the requested comparison or emphasis.
The rhetorical goal determines which notes matter
Synthesis combines selected information into a useful statement. First identify the task: compare, introduce, emphasize, explain a cause, or give an example. Facts irrelevant to that goal can be omitted even if they are interesting or true. Accuracy alone does not make a choice successful.
Preserve the relationships in the notes
When combining facts, check which dates, quantities, and descriptions belong to which person or object. Avoid inventing a causal link, a superlative, or a contrast that the notes do not establish. An efficient answer often uses fewer facts because it selects only what the goal needs.
Worked example
Notes: Cedar opened in 1980; River opened in 1995; both offer free lectures. Goal: emphasize a similarity.
- The opening years show a difference, so they are not central to this goal.
- Free lectures are a shared feature.
Both Cedar and River offer free public lectures.
Watch for this: A statement can be true according to the notes and still fail the rhetorical goal.
Check your understanding
Notes: device A weighs 2 kg; device B weighs 3 kg; both use solar power. The goal is to emphasize a difference. Which answer works?
- Both devices use solar power.
- Device A weighs 1 kg less than device B.
- Solar power is used by both devices.
- Device A uses solar power.
Show answer and explanation
Answer: B. It accurately compares the weights: 3 − 2 = 1 kg.
