To protect their nests from predators, some species of tropical wasps construct nests with narrow, complex entrances that deter larger invaders. While these architectural barriers are highly effective at keeping out predators, they also restrict the airflow inside the nest, causing temperature and humidity levels to rise. The wasps, _______, must actively fan their wings to ventilate the chambers and prevent their larvae from overheating.
Which choice completes the passage with the most logical transition?
- Anevertheless
- thereforeCevap
- Cfurthermore
- Dmeanwhile
Cevap
therefore
The passage establishes that the narrow entrances of the nests restrict airflow and cause temperatures to rise. The following sentence states that the wasps must fan their wings to ventilate the chambers. Since fanning the wings is a direct consequence of the temperature rise, the cause-and-effect transition 'therefore' is correct.
