Question 112·Easy·Transitions
Many cities are turning to urban green roofs to mitigate the heat-island effect. Toronto, _____ has mandated that new commercial buildings include rooftop vegetation.
Which choice completes the text with the most logical transition?
For transition questions, first ignore the answer choices and decide how the ideas before and after the blank relate: Are you seeing contrast, a specific example, a result, a comparison, or just an additional similar point? Once you’ve named the relationship in simple terms, check each option’s usual function (contrast, example, cause-effect, etc.) and eliminate any that don’t match. Finally, plug the remaining choice into the sentence to confirm it makes the logical connection clear and keeps the sentence smooth and natural.
Hints
Look at how the two ideas are related
Ask yourself: Is the sentence about Toronto showing something opposite, something similar, a consequence, or one specific case of the general idea that came before?
Classify each transition type
Without plugging them into the sentence yet, think: Which option usually shows contrast? Which usually shows cause-and-effect? Which usually shows two things doing something in the same way? Which usually introduces a specific case?
Test each option in the sentence
Mentally read the sentence with each choice in the blank. For each one, ask: Does this accurately describe how the idea about Toronto relates to the idea about "many cities"?
Step-by-step Explanation
Understand the relationship between the clauses
Read the full sentence with the blank:
"Many cities are turning to urban green roofs to mitigate the heat-island effect. Toronto, _____ has mandated that new commercial buildings include rooftop vegetation."
The first sentence gives a general statement about what many cities are doing. The second part focuses on one specific city (Toronto) and what it is doing about the same issue. This suggests that Toronto is being presented as one example of the general trend.
Recall what each transition typically signals
Think about the function of each option:
- "however," usually shows contrast (something different or opposing).
- "for instance," usually introduces an example.
- "similarly," usually shows that one thing is like another in some way.
- "as a result," usually shows cause and effect (one thing happens because of another).
Keep these meanings in mind while you match them to the relationship you found in Step 1.
Match the meaning to the sentence context
We decided that the second part about Toronto is a specific example of the general idea that many cities are using green roofs. That means we need a transition that introduces an example, not one that signals contrast, general similarity, or cause-and-effect.
The choice that introduces an example is "for instance,", so the completed sentence is:
"Many cities are turning to urban green roofs to mitigate the heat-island effect. Toronto, for instance, has mandated that new commercial buildings include rooftop vegetation."
