Accepted Answer

# Brief Explanations:
1. For question 1, option D directly implies that bacteria and archaea evolved differently as it mentions they "parted ways long ago".
2. For question 2, the word "look" in the paragraph is related to the meaning of "appearance" as it is used in a context where bacteria's appearance - related aspects are being discussed.
3. For question 3, option D shows a similarity between archaea and eukaryotes as it compares archaeal histones to those in eukaryotes.
4. For question 4, the phrase "use another for food or shelter" in the paragraph defines what parasites are.

# Answer:
1. D. The mirror - image glycerols suggest that bacteria and archaea parted ways long ago.
2. C. look
3. D. Archaeal histones look like simpler versions of the histones found in eukaryotes.
4. A. use another for food or shelter
