Problem: Please answer a question about the following article about North Carolina:
North Carolina was inhabited for thousands of years by succeeding cultures of prehistoric indigenous cultures. Before 200 AD, they were building earthwork mounds, which were used for ceremonial and religious purposes. Succeeding peoples, including those of the ancient Mississippian culture established by 1000 AD in the Piedmont, continued to build or add on to such mounds. In the 500700 years preceding European contact, the Mississippian culture built large, complex cities and maintained far-flung regional trading networks. Its largest city was Cahokia, located in present-day Illinois near the Mississippi River.
Before European contact, who built large cities and regional trading networks?
A: Mississippian culture
Problem: Please answer a question about the following article about Religion in ancient Rome:
Imported mystery religions, which offered initiates salvation in the afterlife, were a matter of personal choice for an individual, practiced in addition to carrying on one's family rites and participating in public religion. The mysteries, however, involved exclusive oaths and secrecy, conditions that conservative Romans viewed with suspicion as characteristic of "magic", conspiratorial (coniuratio), or subversive activity. Sporadic and sometimes brutal attempts were made to suppress religionists who seemed to threaten traditional morality and unity, as with the senate's efforts to restrict the Bacchanals in 186 BC.
What group viewed the mysteries as suspicious or subversive?
A: conservative Romans
Problem: Please answer a question about the following article about Insect:
There are many different patterns of gas exchange demonstrated by different groups of insects. Gas exchange patterns in insects can range from continuous and diffusive ventilation, to discontinuous gas exchange.:6568 During continuous gas exchange, oxygen is taken in and carbon dioxide is released in a continuous cycle. In discontinuous gas exchange, however, the insect takes in oxygen while it is active and small amounts of carbon dioxide are released when the insect is at rest. Diffusive ventilation is simply a form of continuous gas exchange that occurs by diffusion rather than physically taking in the oxygen. Some species of insect that are submerged also have adaptations to aid in respiration. As larvae, many insects have gills that can extract oxygen dissolved in water, while others need to rise to the water surface to replenish air supplies which may be held or trapped in special structures.
Gas exchange patterns can contain what kind of ventilation?
A:
diffusive ventilation
