There were upsides to these trips, I suppose. Mom usually would sing in the car when things got really boring. And, of course, it was always fun watching my sister argue with dad as she made some ardent point about her curfew being too early, or mine being too late. Regardless, it was our arrival at the coast that was the most fun. Depending on what time we did end up getting there, the reception we got from the friends we hadn’t seen since last summer was usually the best part of all. The narrator’s sister would most likely argue A: by making excuses.
B: with a lot of emotion.
C: by using research.
D: without much energy.

B. with a lot of emotion.

Explanation:

I think its B. with a lot of emotion because "ardent" means "enthusiastic or passionate." So the narrator's sister is arguing "with enthusiasm or passion", and a lot of emotion!

given the fact that the question is about the detail that best support the idea that oppressive leaders use   propaganda to achieve thir goals,   the first option does not refer to any kind of propaganda, since it only tells about that the milk and the windfall apple should be reserved for the pigs. in the second option, that is, "snowball and napoleon sent out flights of pigeons whose instructions were to mingle with the animals on the neighbouring farms, tell them the story of the rebellion, and teach them the tune of "beasts of england". it can be identified that the oppressors make use of the propaganda, which is represented by the pigeons, and the information they have to tell other animals about what was happening in the farm in order to get their objectives. for that reason, the right answer is the second option, taking into account that the third option do not refer to propaganda since it only talks about that they did not want jones back. and, finally, the last option refers to the result of the given news, but it does not mean about the propaganda they used to achieve their goals.
