Is this a multiple choice question?
Answer:
Monks Mound is the largest Pre-Columbian earthwork in the Americas and the largest pyramid north of Mesoamerica. The beginning of its construction dates from 900–955 CE. Located at the Cahokia Mounds UNESCO World Heritage Site near Collinsville, Illinois, the mound size was calculated in 1988 as about 100 feet (30 m) high, 955 feet (291 m) long including the access ramp at the southern end, and 775 feet (236 m) wide.[1] This makes Monks Mound roughly the same size at its base as the Great Pyramid of Giza (13.1 acres / 5.3 hectares). The perimeter of its base is larger than the Pyramid of the Sun at Teotihuacan. As a platform mound, the earthwork supported a wooden structure on the summit.
Unlike Egyptian pyramids which were built of stone, the platform mound was constructed almost entirely of layers of basket-transported soil and clay. Because of this construction and its flattened top, over the years, it has retained rainwater within the structure. This has caused slumping, the avalanche-like sliding of large sections of the sides at the highest part of the mound. Its designed dimensions would have been significantly smaller than its present extent, but recent excavations have revealed that slumping was a problem even while the mound was being made.
Several factors can cause tire failure including under inflation, hard braking, and poor wheel alignment.
The process of aligning wheels to the manufacturer's standards is known as wheel alignment. It is sometimes referred to as breaking or tracking. Wheel alignment is a common component of routine auto maintenance.
The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true without "pulling" to one side. Alignment angles can also be altered beyond the maker's specifications to obtain a specific handling characteristic.
Motorsport and off-road applications may call for angles to be adjusted well beyond normal, for a variety of reasons.

Gender roles are a person that has a specific gender (as in male, female, other) and does a specific task. For example, they could be reading a passage.
Answer:
In an open class system, people are ranked by achieved status, whereas in a closed class system, people are ranked by ascribed status.The main difference or basic difference between an open class system and a closed class system is the degree of social mobility within society. This means that according to their type of partnership individuals may or may not mobilize, be independent or occupy an established hierarchical level. Normally social systems are divided into Slavery, Castes, Classes and Estates and each of which has specific characteristics such as A class system or open class system allows the individual to occupy a position within society depending on their level of effort to acquire it, likewise, the individual has the freedom to mobilize. On the contrary, a closed class system admits very little or no mobility for its individuals, an example of this is slavery or castes where mainly people are the property of others or their acts must always obey only specific beliefs and strict principles that they prevent their social mobility or growth in hierarchies.
