Answer:
The setting in this excerpt reveals:
C. a lack of sophistication.
Explanation:
The excerpt offers details of how rudimentary the table, dishes and cutlery were. There is no sophistication; everything about them is rustic - the materials as well as the way they are made. There is wood, horn, pewter. There is a table carved with a broad-axe. There are hunting-knives instead of table knives. If something broke easily - and the author says crockery did -, it was discarded. Durability and usefulness were priorities.
A. Yesterday, Leo had a __more difficult__ time sleeping than today.
B. is incorrect because it is incorrect to say one has "a difficultly time" doing anything; you have "a difficult time" doing something.
C. is incorrect because you can not say "most" when comparing something to something else; you can either say "It was the MOST difficult" or "It was MORE difficult than that."
A. seems to be the correct answer
