How do I finish the reading session on time?
Don't read the whole text! That would only waste your limited time. When the text is given to you, what you should do is skim it, by reading the first sentence of each paragraph, so you have an idea of what it is about. Scroll it all the way down so you can skip to the questions. The questions progress in chronological order, so in order to find each answer you will eventually read the whole text, or at least have deep understanding of it. Knowing the text as a whole is only necessary for the last question.
How do you say "Portuguese is freaking hard, how am I ever gonna learn it?" in Portuguese?
"Português é muito difícil, como eu vou conseguir aprendê-lo?". I know, English-speaker, it looks terrible, specially with so many weird accent marks. But I'll try my best to make it easier for you. I hope that after my help you can ask me how to say "Portuguese is not so hard, and I am actually learning it" instead--by the way, that's "Português não é tão difícil, e eu estou realmente aprendendo".
What is good acting?
Good acting is responding TRUTHFULLY to stimuli under imaginary circumstances, which are given by the playwright or screenwriter. How you respond to stimuli depends on the character's objective. A character has a main objective for the entire play or film, but he/she has smaller objectives in each scene, which determine what his/her actions will be. A scene is a sequence of actions performed by the characters, and they are all directed to the other character, i.e. an action is always a transitive verb, having the other character as an object. How the actor manages to perform truthfully depends on his/her method of training. Stanislavsky was the first to theorize the actor's technique, but after him many different approaches were developed.
