Huy read a visitor guide about a limestone valley before a school trip. The guide explained that caves and rock formations developed over a very long time. It also asked visitors to stay on marked paths and leave stones where they were. Huy wondered whether the easiest path was open after heavy rain, so he contacted the visitor centre instead of relying on an old message. The staff confirmed a safe route and advised the group to bring water. Huy prepared a short talk about why preservation matters. A natural wonder, he concluded, is not only a place for photographs. It is a landscape whose living systems and geological history deserve care.
First identify the central activity. Underline actions and reasons separately; an action tells what happened, a reason tells why. A negative detail can help you reject an attractive but inaccurate option.
