Answer:
1. Cotton Gin: In colonial times, cotton cloth was more expensive than linen or wool because of the extreme difficulty of separating seed from the clinging fibers. One man could pick the seeds from only about 1 pound of cotton fiber per day.
2. Reaper/Binder: Small grains had been harvested by hand for centuries, cut with sickles or scythes, hand-raked and tied into sheaves. Grain harvesting machines first appeared in Great Britain in about 1800, and in the U.S. a decade or two later, but most failed. Obed Hussey and Cyrus McCormick developed successful reapers during the 1830s.
3. Thresher: When grain was being cut by hand, the method for separating the kernels from the straw was equally slow and labor intensive. Grain was hauled to a barn where it was spread on a threshing floor and either beaten with hand flails or trampled by animals. That knocked the kernels free of the straw, which was then raked away. The remaining mixture was winnowed by tossing it into the air where the wind was relied upon to blow the chaff and lighter debris away from the heavier grain, which fell back onto the threshing floor.
4. Combined Harvester-Thresher: By the 1920s the steam traction engine was on it's way out, but it paved the way for the gasoline tractors that followed.

Wanda makes an educated and accurate guess about her friends' behavior in a specific situation. in other words, she is making a hypothesis.
<h3 /><h3>What is a hypothesis?</h3>
It corresponds to an assumption that generates a statement that is deduced through a set of data and information, which is an integral part of scientific studies, which should be the basis for the research question that must be resolved at the end of the study, through the method of qualitative and quantitative data collection and of the experiments that will be carried out.
A hypothesis is a statement that may involve a series of biases, and cannot in fact be judged to be true until proven through the scientific method.
Therefore, hypotheses tested through science can increase understanding of a topic, whether their assumptions are true or false, generating greater reliability about an idea.

Most nations operate in the capitalist system of production and consumption.
Since the end of the feudal system, the world underwent transformations that culminated in economic systems based on barter and mercantilism, which in turn allowed for the existence of industrial revolutions and which were the basis for the capitalist system of production as it is today.
In last century, Capitalism and communism competed for world hegemony until the end of the Cold War, when the bipolarized world gave way to what today times capitalist hegemony in most countries with a few countries in communist systems.
The correct answer would be, The label has caused her to have lower expectations and apply different treatments
The above mentioned statement is exemplified by the teacher's action.
Explanation:
Intellectual Disability is a disability related to brain functioning. The reasoning, functioning and problem solving are affected directly by this disability.
Children with such disability need more attention at their schools while doing their school tasks. When such students are being labelled as disabled, then the teachers who are teaching that student would have lower expectations from that student and they would definitely have a different treatment with that student than others.
This type of teacher's behavior towards a labeled student can cause more complications.
