Answer:
An experiment
Explanation:
The investigation in which a hypothesis is scientifically tested is called hypothesis. In the experiment cause (Independent Variable) and the effect ( dependent variable) is measured and extraneous variables are controlled. The opinions and views of the researcher should not have any effect on the results of a study, it made the data less biased and more valid.
False. The fall was DURING the Middle Ages, not after.
The Roman Empire reigned from 27 BC to 476 CE throughout the Mediterranean world, including parts of Europe, the Middle East and North Africa. The fall of the Roman Empire in the West in 476 CE marked the end of the period of classical antiquity and ushered a new era in world history.
In the Middle Ages, it started with the fall of the Roman Empire: therefore it wasn’t the period.

Innovations in farming techniques that led to great productivity.
1.- <em>Three Point Linkage</em>. Developed by Harry Ferguson, this invention raised or lowered the plough, depending on the depth farmers wanted to dig.
2.- <em>Genetical Modified Corps</em>. Scientist isolate genes with some desirable traits to improve the quality of the plant.
3.- <em>Fertiliser Deep Placement.</em> A new form of fertiliser that increased the Yields.
4.- <em>New Feeding Methods</em>. Blending different components of food to improve the quality of nutrition.
The AG industry was able to provide way bigger amounts of food. With higher amounts and productivity gave farmers a easier time to keep up with the growing population around the world. more people means higher demand for food in larger quantities.
