How is scientific writing different from the style of writing that you learned in ENG 111?  (Select all that are correct.)   Group of answer choices a. Scientific writing is concise, written in 3rd person, and uses past tense. b. Science writing uses lots of colorful language to describe visual reactions to the experiment. c. Science writing uses lots of personal pronouns (e.g., I, me, we, you, your, our) to show ownership of the results and personal attention to directions. d.Science writing assumes the reader already knows how to do the experiment that is the subject of your paper. e.Science writing may include references that are from peer reviewed sources.
