The correct order for adjectives is typically: quantity, opinion, size, age, shape, color, origin, material, purpose.
Looking at the given sentences:
- "He bought three Spanish new books." - The correct order should be: "He bought three new Spanish books."
- "I saw four young girls run by." - This order is correct: quantity (four) followed by age (young).
- "The paper smooth pages are great for writing." - The correct order should be: "The smooth paper pages are great for writing."
- "The French yellow dog is cute." - The order is correct.
So the best responses for correct adjective order is:
- "I saw four young girls run by."
- "The French yellow dog is cute."
Among the four options, the second sentence ("I saw four young girls run by.") is correct in terms of adjective order as it follows the quantity and age order. The fourth sentence is also acceptable.
