Question 74·Medium·Transitions
In recent years, many cities have encouraged the installation of green roofs, which are rooftops covered with vegetation that absorb rainwater and improve insulation. _____ these vegetated roofs can also provide habitat corridors for migrating insects and birds.
Which choice completes the text with the most logical transition?
For transition questions, first ignore the answer choices and read the sentences around the blank to decide the logical relationship (same direction/additional point, contrast, cause-and-effect, example, or time). Look for clue words like "also," "however," or "because" that signal this relationship, then eliminate any options that don’t match that logic even if they sound smooth; the correct transition must accurately reflect how the ideas connect.
Hints
Clarify the two ideas being connected
Restate in your own words what the first part (before the blank) says about green roofs, and then what the second part (after the blank) adds about them.
Use the clue word "also"
Focus on the word "also" in the second clause. What does that suggest about how the second idea relates to the first?
Classify the relationship
Ask yourself: Is the second idea a result of the first, an alternative to it, something happening at the same time, or another benefit of the same thing?
Test each transition in context
Read the sentence with each option in the blank and see which one matches the relationship you identified, not just which one "sounds nice."
Step-by-step Explanation
Understand what each part of the sentence is saying
The first part explains why cities encourage green roofs: they absorb rainwater and improve insulation. The second part says these roofs can also provide habitat corridors for migrating insects and birds. Both parts are listing positive effects of green roofs.
Decide the relationship between the two parts
Ask: Is the second part a result, an alternative, something happening at the same time, or another similar benefit of green roofs? The clue word "also" shows that the second part adds another benefit to the ones already mentioned.
Match the relationship to the type of transition
You now know the blank needs a transition that connects two similar, positive points about green roofs, with the second point added on to the first. Eliminate any choice that suggests cause-and-effect, a different option, or a focus on time.
Evaluate each option and choose the best fit
"Consequently," shows a result; "Otherwise," shows an alternative if something doesn’t happen; and "Meanwhile," focuses on time. None of these simply introduce another similar benefit. "Additionally," correctly signals that the sentence is adding one more advantage of green roofs, so D) Additionally, is the best choice.
