A claim must be arguable but stated as a fact. It must be debatable with evidence. It's not a personal opinion or feeling. It defines your writing goals. A good claim must be specific and is a focused argument.
Here's an example: A teenager wants a new phone because of the following claims...
- Everyone at school has it.
- It's popular.
- It's "useful."
The "Star Trek<span>" </span>effect<span> is the cultural </span>impact<span> that the television show has had on societies where it has been shown regularly since the 1960s. ... But </span>Star Trek<span> was the first television series aimed at adults to tell sophisticated morality tales</span>
The narrator, is the protagonist and she starts explaining that she is a teenager. She knows what the latest styles are, she reads the current editorials, she listens to the radio... She wants us to know that she is not a silly girl. In fact, she is a rational thinker. But in fact, when the boy takes her hand and invite her to the sakiting rink, she abandons all her rationality and she believes when he says that he will call her. When days pass by and he doesn't, she says " I'm not so really dumb".
All that, indicates the conflict: she is a sixteen year old, naive and soft in character behind that tough exterior.
