Exercise 2 Find the Central Idea
Sea butterfly
from Sea butterfly life cycle threatened by climate change, May 2023 at https://www.bas.ac.uk/news/sea-butterfly-life-cycle-threatened-by-climate-change/
Shelled pteropods, commonly known as sea butterflies, are increasingly exposed to ocean changes, but some species are more vulnerable to this threat. In a new study, published this month in the journal Frontiers in Marine Science, British Antarctic Survey (BAS) scientists examining pteropod life cycles in the Southern Ocean have found that some species might be more vulnerable to this threat due to different timings of their life cycle.
- Read the passage
- Find the central idea, ask yourself: “What is the author trying to say about this topic, lesson, or experience?”
Main Idea vs Central Idea
- The main idea is that some sea butterflies are in more danger from changes in the ocean than others.
- The central idea is that scientists discovered that different sea butterfly species grow and live at different times of the year, and this may make some species weaker against ocean changes
The main idea is the general topic of the passage.
The central idea is the important message or explanation the writer gives about that topic.
In this passage:
- Main idea: Some sea butterflies are more affected by ocean changes.
- Central idea: Scientists found that differences in life cycles may make some species more vulnerable.
