Answer:
2. The star is a member of binary eclipsing star system.
Explanation:
The question above shows an example of an eclipsing binary star. This type of star is very variable because the intensity of its brightness varies in the deccore of a few hours. This is because these stars are so close to an observer's field of view on the Earth's surface that they are easily eclipsed, and it is exactly these eclipses that cause the brightness of these stars to vary, which undergo a constant period of approximately 73 hours. intense shine, followed by constant drops in the intensity of that shine (lasts about 2 hours).
Answer: The school board wants you to answer C) Agricultural Revolution, but that is incorrect.
The correct answer would be during the Neolithic Era, so none of the choices would be the right answer.
Explanation: During the Paleolithic Era, which corresponds to the old stone age, people were hunter-gatherers. This means that they obtained food by hunting animals and by gathering fruits, vegetables, and nuts from local plants. So options A and B are pretty much the same thing and incorrect.
Domestication and pastoralism developed during the Neolithic or new stone age when people discovered that, if they took care of certain plants, they would grow again and give them more food. Domestication is not the same thing as agriculture (even though the school system continues to teach it this way).
The Agricultural Revolution actually refers to a much later period in history, during the 18th century in Britain, when traditional agriculture went through a process of transformation. This is way after domestication and pastoralism.
Finally, option D is also incorrect because classical civilizations like Greece and Rome already had full-scale agriculture and had already gone through the process of domestication and pastoralism.
D is the correct answer.
