Question

Like a boil that can never be cured as long as it is covered up but must be opened with all its pus-flowing ugliness to the natural medicines of air and light, injustice must likewise be exposed, with all of the tension its exposing creates, to the light of human conscience and the air of national opinion before it can be cured.

Answer 1

Simile

Step-by-step explanation:

Saying it cant be cured until its brought out into the light even if people dont like it

Answer 2

It is mandatory to expose the injustice to ease the problems ,like exposing a boil to air and light to cure it.

Step-by-step explanation:

Injustice means anything unjust and not fair. Suppose if a person is innocent and he is given punishment then it will be considered as injustice. It is of utmost importance to expose the injustice otherwise it might lead to disastrous circumstances.

Until the injustice is exposed we will not be able to find the cure and tension will remain the same. But once it is exposed all the problems are solved. It is the same as a boil which when exposed to air and light is cured automatically.
