From my my experience this usually differs depending on the type of book it is, but I think the best choice is either A, to help the reader understand new concepts, or C., It allows the reader to focus on key ideas and information during the reading. I'd pick C though, since it's more in depth and makes more sense.
B. doesn't make that much sense unless the book is an argumentative or a persuasive book.
D. only applies to personal narratives. Nobody can understand a writer's personal experiences and attitudes otherwise.
As an English speaker the advice i give to someone who wants to learn English would be it does take time but it's actually not that hard to learn English you just need to keep practicing and try to talk with the words you know so you can get used to it.
Answer:
1. Apollo promises he will give his son any gift but that of allowing him to drive the chariot.
2. Apollo tells his son that not even other gods can drive his chariot.
3. Apollo explains what will happen if his son drives his chariot.
4. Apollo reluctantly gives in to his son's request to drive the chariot.
Explanation:
When Phaethon went to his father the sun god- Apollo, to confirm his legitimacy, his father assured him that he was indeed his son. Awed by his father's magnificence and the sun-chariot, Phaethon made a request to drive the chariot when told by his father to make any request. Phaethon insisted on driving the chariot and since his father already gave his word, he could not go back on it.
Apollo initially resisted the idea and told his son to make another request. He explained that not even other gods like zeus could drive his chariot. He explained how the chariot worked and the dangers involved in it. When his son refused still insisted, he eventually had to keep his word by letting his son drive the chariot.
