A rough draft is the preparation for a final essay and as I see it a rough draft may contain all of the elements mentioned in the given options. For example, prepositions, nouns and adverbs are also sure to be included, since it is a written piece and these are central components of any language. Transitions will probably be utilized, as you will probably build up a few points in your exposition and should change from thought to thought.
Assure could mean making sure something happens, to comfort or remove doubts from a person, or make someone sure of something.
If it's one word answers it could be persuading, guaranteeing, promising, convincing, reassure, satisfy, or tell.
I hope this helps without answer choices it's kind of hard to know what kind of answer you need. Have a great day!
Answer: A) He has already been to the asteroid.
Explanation: In the given lines we can see Kenniston talking to another person, they are discussing whether or not they have to go back to an asteroid and that in order to do that, they need to find a ship. An inference is something that the text doesn't say in a literal way, but that we can understand when we read the text, in this case we can infer that Kenniston has already been to the asteroid because he said "we've got to get back".
B
Not A or C because they I traduces new information to the paragraph, and this cannot be conclusions. Not D because it is off topic
