Two artifacts found in the same stratigraphic layer are assumed to be of similar age due to the Law of Association.
The principal laws of the association are contiguity, repetition, attention, pleasure-pain, and similarity. The fundamental legal guidelines were formulated with the aid of Aristotle in about 300 B.C. and by way of John Locke in the 17th century.
Aristotle counted 4 laws of association when he examined the techniques of remembrance and recall: The law of contiguity things or events that occur near each other in space or time tend to get related collectively in the thoughts. Laws of the association are the principle underlying the connections inside the memory between certain ideas, feelings, or behaviors.
Aristotle's analysis of gaining knowledge of memory consists of four laws of association: the legal guidelines of continuity, assessment, frequency, and similarity. Accounting for learning and reminiscence in phrases of such legal guidelines of affiliation is referred to as institutions.

Answer: Renaissance
Explanation:
The Renaissance literally means “rebirth”. The Renaissance changed the world. You might even say it created all of what we now know as modern life.
Farming typically employs the most Hispanic workers.
A radioactive element with a half-life of 1,000 years, and starting mass of 20 grams, will need 2,000 years to decrease to 5 grams.
Explanation:
The radioactive elements all have a specific half-life. Each element's half-life is well known, and they are used by scientists of numerous fields as they are excellent for determining the age of a particular item, be it or organic or non-organic nature. In this case, we have a radioactive element with a half-life of 1,000 years, and starting mass of 20 grams.
The half-life basically means that half of the mass of an element is lost during a particular period of time. For the element in question we need to find out how much time will be needed for it to decrease to 5 grams. In order to get to the result, we just need to add 1,000 years on every decrease of half of the mass:
20/2 = 10
10/2 = 5
So in 1,000 years, the element in question will decrease to 10 grams, and in further 1,000 years (2,000 cumulatively) it will decrease to 5 grams.
