The problem: Answer a question about this article:
John Locke, one of the most influential Enlightenment thinkers, based his governance philosophy in social contract theory, a subject that permeated Enlightenment political thought. The English philosopher Thomas Hobbes ushered in this new debate with his work Leviathan in 1651. Hobbes also developed some of the fundamentals of European liberal thought: the right of the individual; the natural equality of all men; the artificial character of the political order (which led to the later distinction between civil society and the state); the view that all legitimate political power must be "representative" and based on the consent of the people; and a liberal interpretation of law which leaves people free to do whatever the law does not explicitly forbid.
Which English philosopher wrote Leviathan in 1651?
****
The answer: Thomas Hobbes

Problem: Please answer a question about the following article about Sexual orientation:
One person may presume knowledge of another person's sexual orientation based upon perceived characteristics, such as appearance, clothing, tone of voice, and accompaniment by and behavior with other people. The attempt to detect sexual orientation in social situations is known as gaydar; some studies have found that guesses based on face photos perform better than chance. 2015 research suggests that "gaydar" is an alternate label for using LGBT stereotypes to infer orientation, and that face-shape is not an accurate indication of orientation.
What have somes studies show when researching how someone uses "gaydar"?
A: that guesses based on face photos perform better than chance

Question: Read this and answer the question

Stereophonic sound recording, which attempts to provide a more natural listening experience by reproducing the spatial locations of sound sources in the horizontal plane, was the natural extension to monophonic recording, and attracted various alternative engineering attempts. The ultimately dominant "45/45" stereophonic record system was invented by Alan Blumlein of EMI in 1931 and patented the same year. EMI cut the first stereo test discs using the system in 1933 (see Bell Labs Stereo Experiments of 1933) although the system was not exploited commercially until much later.

What was the benefit of 45/45 stereo sound?
Answer: more natural listening experience

Problem: According to the preamble in The Law of Treaties, treaties are a source of international law. If an act or lack thereof is condemned under international law, the act will not assume international legality even if approved by internal law. This means that in case of a conflict with domestic law, international law will always prevail.
What are started to be a source of international law in the preamble in The Law of Treaties?
The answer is the following: treaties

During Reconstruction, freedmen and former free people of color were granted the right to vote; most joined the Republican Party. Numerous African Americans were elected to local offices, and some to state office. Following Reconstruction, Tennessee continued to have competitive party politics. But in the 1880s, the white-dominated state government passed four laws, the last of which imposed a poll tax requirement for voter registration. These served to disenfranchise most African Americans, and their power in the Republican Party, the state, and cities where they had significant population was markedly reduced. In 1900 African Americans comprised 23.8 percent of the state's population, concentrated in Middle and West Tennessee. In the early 1900s, the state legislature approved a form of commission government for cities based on at-large voting for a few positions on a Board of Commission; several adopted this as another means to limit African-American political participation. In 1913 the state legislature enacted a bill enabling cities to adopt this structure without legislative approval.
What percentage of the Tennessee population was African-American in 1900?
23.8

Here is a question about this article: It is now known that the molecular circadian clock can function within a single cell; i.e., it is cell-autonomous. This was shown by Gene Block in isolated mollusk BRNs.[clarification needed] At the same time, different cells may communicate with each other resulting in a synchronised output of electrical signaling. These may interface with endocrine glands of the brain to result in periodic release of hormones. The receptors for these hormones may be located far across the body and synchronise the peripheral clocks of various organs. Thus, the information of the time of the day as relayed by the eyes travels to the clock in the brain, and, through that, clocks in the rest of the body may be synchronised. This is how the timing of, for example, sleep/wake, body temperature, thirst, and appetite are coordinately controlled by the biological clock.[citation needed]
What is the answer to this question: By functioning within a single, what is the system?
****
So...
cell-autonomous
