The Hopi are a Native American tribe who primarily live on the Hopi Reservation in northeastern Arizona.
The given passage tells us about their relationship with nature. We can see that they have only positive feelings about nature, that they respect it. They know that it came first. Many creatures that surround us were already a part of this world before we, humans, appeared. They respect nature because of that, and because it was made for us. Without other lifeforms surrounding us, we wouldn't have been able to survive and develop as we did.
Thus, the correct option is D.
Many responsibilities are needed, patience and understanding.
The difference between an interval schedule of reinforcement and a ratio schedule of reinforcement is the following:
Interval schedules of reinforcement are those where the response is rewarded only after an amount of time has elapsed. If the amount of time elapsed is a <em>specified amount of time</em>, the interval schedule is fixed, if it is an<em>unpredictable amount of time</em>, the interval schedule is variable.
Ratio schedules of reinforcement, on the other hand, are those where a response is reinforced only after a number of responses. If the number of responses is a <em>specified number</em>, the ratio schedule is fixed; if it is an <em>unpredictable amount of responses</em>, the ratio schedule is variable.
