Answer:
The given sentence is true.
Step-by-step explanation:
William Blake, in his poem, 'The Poison tree', explains that the suppression of one's emotion will lead them to more dangerous situations in the future. This poem might look like it focuses on anger. But the poet tries to explain the adverse effects of suppressing the anger in an individual and his surroundings.
If a person does not admit, acknowledge and expose the anger, he might allow the emotion to grow inside. It will, in turn, give rise to vengeance and other destructive qualities in him.
