Which phrase in this excerpt from a 1964 interview with malcolm x indicates that he is explicitly stating an opinion? "i think all of us should be critics of each other. when you can't stand criticism you can never grow. i don't think that it serves any purpose for the leaders of our people to waste their time fighting each other needlessly."

The correct phrase is "I don't think that it..." :)

  I believe that the phrase that indicates that Malcolm X is stating an opinion is given in two sentences, when he uses "I think..." and "I don´t think...".

 The fact that he select the word think shows that he is validating the argument on his own opinion and not using other authors or references to make a point.

  I hope that the answer and explanation are correct.

compare & contrast informative essay/speech

when speaking or writing for the sole purpose of providing information in order to give audience members a good basis for making a decision, you would present an informative speech or essay.   because you wouldn’t want to be persuading the audience by arguing for one type of exercise over the other, you wouldn’t choose a persuasive/argumentative technique.   to fairly, and without bias, present information about the pros and cons of each type exercise, a compare/contrast, informative speech/essay would be the best bet.
