The answer is D. a placebo effect.
Explanation:
Placebos can be described as "fake" medication or treatment which intends to appear as real. Hence, the placebo effect occurs when a person affirms that he was a affected in any particular way, while there was no reason for that to happen.
For example: a person is asked to take a cup of "very high-caffeine coffee" and describe his symtpoms. The person then states that he feels very alarmed, and that his heart is racing. If at the end it's revealed that it was actually <u>decaf</u> coffee, it's likely the person was under the placebo effect.

Answer:
Tenochtitlan was the capital of the Aztec Empire in the southern part of the Valley of Mexico in the 15th and early 16th centuries. The Aztecs founded Tenochtitlan in 1325 on the island of Lake Texcoco, which was expanded as the city's population grew. Roads led to the city from the mainland, and there were bridges between the islands.
Tenochtitlan covered an area of 8 to 13.5 km². The city had a maximum population of 300,000 to 500,000, more than any European city at the time.
The oldest buildings in Tenochtitlan were in the center. There were several palaces in the city. The largest of these was the palace of the ruler, which was four hectares in size. In addition to the ruler's residence, the palace had administrative premises, food and clothing stores, prisons, and halls, courtyards, and gardens. The sacred buildings were separated from the rest of the city by a wall. From the holy district, the main streets started in every direction, and they divided the city into four parts. The main streets were straight and wide. There were large market markets in the city center, where food and jewelery, for example, were sold. Two aqueducts came to the city, bringing water from miles away, and the problems caused by the floods were reduced by a 15-kilometer dam.
