Answer:
While these mounds take many forms and served different purposes, with each in a sense telling its own story, all were built entirely by hand, usually by piling up earth one basket-full at a time. Some served as burial mounds for the honored dead, while other flat-topped mounds were parts of large cities or towns and held temples or ceremonial buildings, and still others were built in the shape of giant animals.
When a researcher accidentally influences how participants behave, this effect is referred to as placebo effect
<h3>
What is placebo effect?</h3>
The placebo effect occurs when a patient receives a "dummy" treatment such as a placebo and their physical and mental health improves as a result.
In a placebo effect, the patient only reacts to the treatment because they think it is having an impact on them.
Much like when you give a youngster sugar tablets to take the edge off of their agony, they take them like medicine and feel better.
<h3>How does the placebo effect work?</h3>
Because it tricks the brain into thinking it is healing itself by releasing hormones that make you "feel good," the placebo effect is very potent. Therefore, when your doctor prescribes a placebo, they do not inform you that it has no effect; rather, they inform you that it will help you with your illness.

Spanish Empire:</h2>
1. The Spanish claim colonies in the Americas
2.The Spanish take gold and silver from the Americas
3.Gold and silver fund Spain's “golden century"
The earliest event which helped Spain's rise as a major world power was the proclamation of colonies in the Americas. After Columbus accidentally discovered the Americas, Spanish showed interest in the new world. And due to the In<em>ter caetera</em> papal bull of 1493 , the Spanish Empire could solidify its claimed over those lands. After that, the globe was divided into 2 hemispheres between Spain and Portugal.
Then came the moment, when the Spanish started taking gold and silver from the Americas. Exploiting the Americas' silver and gold mines became the Spanish's mainly fund source for a long series of European and North African wars.
And finally because of that fund source, Spanish enjoyed a cultural golden age in between XVI and XVII centuries, which is commonly known as the "golden century".
