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.
I believe the answer is A
The following is a subsurface event that places during the rock surface is Melting. This is further explained below.
<h3>What is
Melting?</h3>
Generally, As the name implies, melting is the process through which a solid becomes a liquid at high enough temperatures. This transition takes place at a predetermined temperature, known as the melting point, in a pure crystalline solid.

The answer is<u> "Jamie has not used true random assignment to conditions."</u>
Random assignment alludes to the utilization of chance methods in psychology analyses to guarantee that every member has a similar chance to be relegated to any given gathering.
Study members are randomly allocated to various groups, for example, the experimental gathering, or treatment gathering. Random assignment may include such strategies as flipping a coin, moving dice, or allotting arbitrary numbers to members.
Note that random assignment varies from random selection.
