Select the most appropriate option to fill in blank no. 5.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e. lungs.
Context: The passage is talking about the importance of forests in absorbing carbon dioxide and helping slow down climate change. It compares forests to an organ of the human body to show their role in keeping the planet healthy.
Meaning of the words:
-
Feet – not related to breathing or environmental function
-
Lungs – organs used to breathe, take in oxygen and release carbon dioxide
-
Brain – controls thinking and bodily functions
-
Chest – part of the body, but not a specific organ
Correct word: Lungs – because just like lungs help in breathing and managing gases in the body, forests help in filtering the air and managing carbon dioxide on Earth.
Reason: Forests act like lungs for the planet by absorbing carbon dioxide and releasing oxygen, which is very important to slow down climate change. So, the best comparison is lungs, not feet, brain, or chest.
Final Sentence: Forests are the lungs of the planet and serve as the home, market and apothecary of people living on it.
Hence, the chosen option is correct.
