Please, someone correct this report I have written as homework?

In the first paragraph, you should write "and the bribing of congressmen.". Plural is better here. Also, "raising the living standards of Brazilian people and ending corruption", because it's contribute to ... and ending corruption. Also, in the following sentence "These are themes that dominate ...", without the final -s. In the second paragraph it should be written "and it doesn't settle millions of families", it's plural. Also, I would replace the contractions don't, doesn't, can't and contractions of that type by their full versions(do not, does not, cannot). It's more formal that way.
