Among the choices, option B. Hasn't, is a singular contraction. "Hasn't" is the shortened word for "has not". The rest of the choices are plural contractions: Don't from do not, Haven't from have not, and Weren't from were not.
You begin with the largest to the smallest. First revise the overall structure. make sure you have introductory paragraph, followed by supporting paragraphs. then summary and closing paragraphs.
After the paragraphs are correct then you can go in and revise sentences that do not belong. either reword or remove.
The final step is the words. making sure they are spelled and used correctly
If a proposition is true, then we say it has a truth value of "true"; if a proposition is false, its truth value is "false". For example, "Grass is green", and "2 + 5 = 5" are propositions.
hope this helps :)
