Help please giving best answer brainliest

So, exactly whats the question? All i see is paragraphs, i need the main question.

Explanation:

right angles are formed by perpendicular lines. if the lines would extend, to make two intersecting lines, they would form four right angles.

i think it's either 'to expose the corruption of the communists in russia', or 'to criticize animal brutality by communists in russia.'  

hope this ! : )
