For that opening sentence, I'd go with something along the lines of this:
"If I had to summarize my summer vacation, I'd say it was uneventful, but enjoyable."
"My summer vacation was busy to say the least."
"I didn't have the best time with my summer vacation, but it certainly was a vacation."
"I spent my summer vacation the way kids are supposed to; doing absolutely nothing."
"This year's summer vacation was the best I've ever had, and I'd love to tell."
Answer:
C) decide to do so.

According to the passage, Thomas DeQuincy indicates that if you push your memory enough, it will be possible to remember people's names. It requires some effort, but it is not impossible, and the results may be quite surprising. Most of the times it is not about a lack of interest, it just happens because this information goes unnoticed.
I'm not sure but i think D would be correct, hope this helps some :)
