One fundamental change that marks the beginning of the Neolithic period is:

A. year-found settlements.
B. use of the bow and arrow.
C. weaving
D. use of stone tools

I think it's A, but not sure.

Please proofread what you typed for A.

See paragraph 3.

If you meant "year-round," then I agree with you.

To determine the correct answer, we need to understand what the Neolithic period entails and what fundamental changes occurred during this time. The Neolithic period, often referred to as the New Stone Age, began around 10,000 BCE and marked the transition from a nomadic hunter-gatherer lifestyle to settled farming communities.

Now let's analyze each option:

A. Year-round settlements: This option suggests that one fundamental change during the Neolithic period was the establishment of permanent settlements. These settlements allowed people to live in one place throughout the year rather than following their prey or seasonal food sources. This change is indeed a key feature of the Neolithic period.

B. Use of the bow and arrow: The invention of the bow and arrow is associated with earlier prehistoric periods, such as the Paleolithic or Mesolithic, rather than the Neolithic period. While the bow and arrow were undoubtedly significant advancements in hunting technology, they do not define the Neolithic period.

C. Weaving: Weaving, or the production of cloth, is a complex skill that emerged during the Neolithic period. However, it is not a defining characteristic that signals the beginning of the Neolithic period.

D. Use of stone tools: The use of stone tools predates the Neolithic period and was characteristic of earlier periods, such as the Paleolithic. While the tools used in the Neolithic period might have differed somewhat from those in earlier periods, the use of stone tools was not a unique development during this time.

Based on this analysis, the correct answer is A. Year-round settlements. This fundamental change in human settlement patterns represents a significant shift from the previous hunter-gatherer lifestyle and marks the beginning of the Neolithic period.
