Answer:
A). The first passage is written to persuade children, and the other to educate adults.
Step-by-step explanation:
The key difference in both the given passages that could be explored while contrasting is that 'the first aims to persuade the children to join summer camp, while the another aims to educate the adults about the significance of summer camps.' The first paragraph adopts a descriptive language reflected by words like 'amazing summer, great hill, awesome summer staff, etc.' that helps in convincing the children more effectively while the second adopts a more informative tone and objective language(reflected by revelation of facts like 'studies show...good health...reason..many American..join..youth experiences'). Thus, option A is the correct answer.
