Each conversation question has a prefix 'Q:' followed by the answer prefix 'A:', and the follow-up question has a prefix 'FOLLOWUP_Q:'.

CONTEXT: The message of American History X is quite simple: violence begets violence. The whole film is a series of escalations based on revenge; Derek and Danny lose their father and hate consumes them. They win a basketball game against the black gang (and their turf in the process) and the gang try and steal their fathers' truck as revenge, Derek kills them over it. But then Derek's arrest interrupts this pattern, he goes off to prison and with the help of Dr. Sweeney he realises the pattern of behaviour and does what he can to prevent it from going any further. Derek has his catharsis and becomes a different person, and tries to help Danny do the same. But the problem is the same hasn't happened to those that he's wronged; there are still people out there from the black gang who have lost friends and blame them both for it, and in the end Danny pays the price. It is much more poignant and reflective of real life in this way, after years of fighting it's not so simple to drop everything and get the happy ending Hollywood has taught us is waiting. <sep> Q: Why did American History X end so unexpectedly?

CONTEXT: It's a figure of speech, sometimes when people speak, they refer themselves in third person perspective. Could be various reasons. In some cultures, people usually address themselves in third person perspective because they believe that addressing themselves in first person is not good. This incident is called Illeism (from Latin ille meaning "he, that") which is the act of referring to oneself in the third person instead of first person. Illeism is sometimes used in literature as a stylistic device. In real life usage, illeism can reflect a number of different stylistic intentions or involuntary circumstances. In this matter, Sparrow refers herself in third person because she needs to give the herself lofty airs, to puff herself up or illustrate her egoism. <sep> Q: Why does Golden Sparrow always use "she" instead of "I" or "My"? A: This incident is called Illeism (from Latin ille meaning "he, that") which is the act of referring to oneself in the third person instead of first person <sep> FOLLOWUP_Q: Is Golden Sparrow a single lady?

CONTEXT: He made that rock formation himself to catch fish. The arrangement of rocks into that shape is a traditional fishing technique called a fishing weir. Quite a few Native American tribes used this kind of fishing technique to catch freshwater fish. The rock formation forces the fish swimming downstream into a small area where they can't easily escape, and can be grabbed by the person fishing. From what I've read, it's actually not likely that a real fisherman would have used a weir in such a shallow stream; in those cases you could typically just grab the fish by hand as they swam in front of you. Nonetheless, it is a valid fishing technique in other cases. <sep> Q: Did someone arrange rocks in a U shape? A: Quite a few Native American tribes used this kind of fishing technique to catch freshwater fish <sep> FOLLOWUP_Q: What is the purpose of arranging the rocks this way?
Yes
