Her lachrymose demeanor was understandable given the loss of her brother; indeed, most of us were rather dolorous.
The words lachrymose and dolorous are adjectives that are used to show sorrow or a somber mood. lachrymose means tearful while dolorous means expressing great sorrow. In this instance, we can see that the people in this sentence were grieving the loss of someone. Her brother had died and it was a sign of sadness. She could not show happiness as she had shown before considering her loved one had passed on. We can also see that the rest of the people were also not in a happy mood and were also grieving.
I'm pretty sure it is c enraged
the word incensed means very angry or enraged
I would say c. timelessness of the message.
Why? Because:
a) your piece of writing has to have a message - if there is no message, there is no point in writing it.
b) you have to have an intended audience you are writing for - it is not the same writing something for your friends, little brother/sister, professor or a potential employer.
c) the format of the message is important because of the previous factor and because the format usually affects the reception of the writing; nobody will be interested in your text if you write it without commas, fullstops, capitalized letters at the beginning of the sentence, or for example, without spaces between the words because it would be too confusing.
While, the timelessness is not as important. You are writing it for a special purpose now, and if it is good it might become timeless. But there are probably many great works (poems, scientific papers, novels, etc.) that were lost or forgotten, but that does not mean they were not great or significant.
Hope my answer is not too confusing :)
