Let's look at South America today: the two languages spoken there are Spanish and Portuguese.
This is because almost all the countries in South America used to be either a Spanish or Portuguese colony, and this is also the correct answer: Spain (who divided its colonies into Vice-royalties ) and Portugal
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.

The correct answers are treatment; depression levels.
Answer 1: The independent variable (IV) in this study is the treatment the clients receive; that is, whether or not they received <span>cognitive-behavioral treatment. An IV is an experimental variable in a study that is controlled and manipulated in order to measure its effects on dependent variables or outcomes.
Answer 2: </span>The dependent variable (DV) in this study is the clients' depression levels. DVs refer to outcome variables or results that are obtained as a result of manipulating an IV. In this instance, the manipulation of the IV (whether the participants received cognitive-behavioral treatment or were instead wait-listed) led to the DV- clients' depression levels. Specifically the researchers were investigating whether receiving the treatment had an influence on clients' depression levels.
The procedure that must be carried out when a motorboat <span>is crossing paths with a pwc is that the rules of the road should be implemented to the situation. To add up, a PWC is considered to be a much powerful boat compared to a motorboat and strict road regulations for the sake of safety.</span>
