You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng. The instrument was said to resemble a wine jar six feet in diameter, with eight dragons positioned face down along the outside of the barrel, marking the primary compass directions. In each dragon’s mouth was a small bronze ball. Beneath the dragons sat eight bronze toads, with their broad mouths gaping to receive the balls. When the instrument sensed an incoming seismic wave, one of the balls would drop and the sound would alert observers to the earthquake, giving a rough indication of the earthquake’s direction of origin. The device is said to have been very accurate and could detect earthquakes from afar, and did not rely on shaking or movement in the location where the instrument was positioned. The first ever earthquake recorded by this seismograph was supposedly somewhere in the east. Days later, a rider from there reported this earthquake. Moreover, it had the most wicked ornaments. They don’t make scientific instruments like they used to! Of course, the insides of the seismometer was filled with a sensing mechanism of some sort, the contents of which have been lost in time. In all likelihood, a simple or inverted pendulum was employed, according to experts.
Geological considerations to identifying physically safe places for human habitation are:
- The strength of underlying geology
- Faults in earths crust that can potentially cause earthquakes
- The steepness of hillsides
What is geology?
- It is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time.
- Modern geology significantly overlaps all other Earth sciences, including hydrology and the atmospheric sciences, and so is treated as one major aspect of integrated Earth system science and planetary science.
- Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure.
- It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.
- Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates.

Answer:
The most acceptable zone with friends is A. Personal distance.
Explanation:
Edward T. Hall developed an idea known as Proxemics, which centers on the idea that every individual can use his/her space a certain way and the effects it can have on our social interaction, behavior, etc.
There can be 4 horizontal distances:
- Intimate: touching, embracing.
- Personal: interaction with close friends, family.
- Social: interaction with people one knows but is not that familiar with, such as coworkers.
- Public: with the general public.
In this case, when an individual has an encounter with good friends, he/she tends to stay in the personal distance. It would become an intimate distance if we are talking about a couple or really close friends but in this case, since it is most of the individual's friends, the interaction stays in the personal distance.
Answer:
This means that the best is being expected from the person despite the fact of the challenging physical ability or capability.
Explanation:
Dementia is a chronic disorder, and a collective term for declining memory and other thinking skills that negatively affect someone, preventing him from performing his daily activities normally.
This disorder is common to old people, and some of its causes are HIV, parkinson disease, Alzheimer's disease and traumatic brain injury among others.
Cholinesterase inhibitors and memantine are commonly prescribed medicine for dementia.
