SELECT ONLY ONE
Only I follows
Both I and II follow
Only II follows
Neither I nor II follows

Answer 1

The conclusion that follows is that all national parks are forests.

Therefore, only I follows.

Step-by-step explanation:

The given statements are:

1. All national parks are parks. 2. All parks are forests.

From these statements, we can draw the following conclusions:

I. All national parks are forests. This conclusion is correct because if all national parks are parks and all parks are forests, then all national parks must also be forests.

II. Some national parks are not forests. This conclusion is incorrect because if all parks are forests, then all national parks, being a subset of parks, must also be forests. So, there cannot be any national parks that are not forests.

Therefore, only I follows.
