SAT CR Questions

12 is very tricky for me. I'm stuck between A and B, but I'm leaning towards A. Motives, from what I understand, are reasons for doing something. Therefore, the questions seem more like hypotheses. But the narrator seems to be objecting to the implications more so than he is assessing the aptness. There's no answer key that I can find so I have no solid confirmation, unfortunately.

Also another question:

15 states: The exchange in lines 42-46 primarily suggest that the narrator's parents were:

B) inquisitive and skeptical
E) loving and affectionate

Those two choices are the only feasible ones. I chose E, but I’d like it if someone can confirm this as well.
Thank you.

12 I would agree is A. The author offers a hypothesis (“Was he lacking in talent?”) and then examines if it’s correct or not.

For 15, I also think there is more evidence in those lines for loving and affectionate: “picking me up in his arms and kissing me…”

Thank you. And one more question

The author uses the descriptions in lines 27-30 (light… petticoat) in making the point that her memories of the past are
D) inconsistent
E) incomplete

These two words are so close in definition. I would have chosen incomplete but an argument can be made for either can’t it?

I would also have chosen “incomplete.”

“Inconsistent” is most often used in comparisons. There has to be some “correct” record for your version of events to be inconsistent, right? What would she be comparing her memories to? What other version of events is there?

Yes, it’s “incomplete” because “only shards of it floated into my ken,” meaning the narrator has only broken pieces of memory rather than a complete, unbroken memory. “shards” don’t suggest inconsistency; they suggest incompleteness.
