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.

Answer:
The best explanation for this phenomenon is <u>PRIMING</u>
Explanation:
Primingcould be defined as a technique in which the introduction of one stimulus influences how people respond to a subsequent stimulus. Priming works by activating an association or representation in memory just before another stimulus or task is introduced.
Priming is the process by which perception or experience of an item (or person or event) leads to an increase in its accessibility and the accessibility of related material and behaviors. therefore priming is what happens when exposure to some thing influences the behavior of an individual later on, without that individual being aware that the first thing is guiding their behavior to a certain extent.
The person was exposed to a scary movie which latter affected his behaviour when he witnessed an argument which he probably think will end in a fight.
Answer:
NNP ; GNP
Explanation:
NNP stands for Net National Product and the full form of GNP is Gross National Product.
Net National product is the value of the total products which is obtained by deducting the monitory value of the goods depreciated over a course of time from the gross national income.
Thus, NNP = GNP - depreciation
