The correct answer is D. Have other scientists repeat the procedure and obtain the same results.
Explanation:
One of the most accurate ways to validate the results of an experiment is to allow peers (other scientists) to review the experiment and repeat it, which is known as replication. This process is required to make sure the results are accurate because if the experiment is repeated by a different scientist and the results are different this shows the data is not consistent and therefore the results are invalid. Moreover, inconsistency or lack of replication can occur due to incorrect processes or bias by the scientist.
According to this, the next step in this situation is to "have other scientists repeat the procedure and obtain the same results".On the other hand, repeating the experiment but changing one of the variables or the procedures is not a correct step because this will change the essence of the experiment and lead to different results.
How did using metal help ancient Chinese people increase food production? It led to wet farming for rice. It led to planting crops in rows. It led to stronger plows for tilling.
How they grew food: Rice and millet were the two main crops grown in Ancient China. Rice paddy (field) flooded from river. Rice needs a lot of water, so the Chinese figured out how to flood the fields from rivers to make rice paddies (fields for growing rice).
How did the Chinese improve farming?: By the Tang dynasty (618–907), China had become a unified feudal agricultural society again. Improvements in farming machinery during this era included the moldboard plow and watermill. Later during the Yuan dynasty (1271–1368), cotton planting and weaving technology were extensively adopted and improved.
