Answer:
One theme of “The poison tree” is the importance of expressing rather than suppressing your feelings” is a TRUE statement.
Step-by-step explanation:
This statement is true because the author depicts the theme that if a person suppresses his feelings, it gets cultivated inside and can lead to consequences. Acknowledgement and expression of anger is very important as it stops from germinating and leading to adverse effects. Suppression of anger is not beneficial in most of the circumstances and thus the allegory is emphasised on the denial of the feelings.
