Hard to judge without the context of the other sentences of the story but if I had to guess, it sounds "inviting and familiar" to me.
<span>The novel is told in flashback - at the start, we meet Ruku as an elderly woman reflecting on the events of her life. This structure allows Ruku not only to narrate her life experiences but also to analyze them, helping the reader to see how she learned and grew from each event. The novel is also divided into two parts: Part one covers the majority of Ruku's married life; the much shorter part two deals with Ruku and Nathan's failed attempt to move to the city after losing their land and contains the falling action of the novel. The first chapters (Ch. 1-3) deal with Ruku's transformation from an uncertain child bride to a confident young wife and mother. These chapters are mostly without hardship - the family is poor but has enough to eat; Ruku and Nathan begin to realize they will never own their own land but have hopes that their children may some day rise out of poverty. The one obstacle Ruku must overcome, her temporary inability to have sons, is nearly forgotten after she has five sons in as many years</span>
The common synonyms are usually unknown, uncertain, unclear, etc.
Answer:
The answer to Part A would be Ignorant, as the author goes on to state that his youthful understanding had struggled in vain. If someone is ignorant of something, yet they do not take the time to actually go research or learn about that thing, then they would be struggling in vain because they are selfish and not taking time to research what it is that the other person is saying that they do not understand.
For the answer to Part B, I would say that (Frederick) Douglass' new awareness of how owners maintain control over slaves allows him to better understand how to improve his situation. I say this because he seems to have an awakening/epiphany in the very last line: "I now understood what had been to me a most perplexing difficulty".
