4) infinitive
163-The wife asks if it is customary in King Arthur's household for a husband to be so standoffish towards his wife.
165-She reminds the knight that she is his love and wife, and the one who saved his life.
170-She says that she has never done wrong by the knight. Why, then, is he treating her this way on their wedding night?
172-The hag says her husband is acting like a crazy man. What is her guilt? She demands that her husband tell her what she has done wrong, promising to correct it if she is able.
174-The knight replies that the hag will never be able to fix the problem, which is that his wife is so ugly, old, and low-born that it's no surprise he tosses and turns.
175-He wishes God would break his heart within his breast.
Letter- This is credible, but not as much so as the others. A letter sent to Grandma Ella still must be credited if it was copied and shared, but it does not have valuable information and cannot be useful to one's knowledge.
Newspaper- This is very credible. Newspaper articles contain valuable information as in facts and statistics as well as opinions and point of views. Newspapers are also updated often so no information is old, unless you read an old article.
Data- This is also credible but supplies more information than credit. An analysis normally consists of numbers or percentages, which can still be credited but not as easily. Data consists of most people's opinions normally, as this is still a fact.
Radio- This is the least creditable. Radio stations talk about weather and current gossip, including pop stars, sports, etc. This is very hard to credit as it is live and cannot be credited without a recorder or a very good memory.
I believe I assisted, do well!
