1. During the 1970s, a new type of pet became popular in North America. Although they were actually just brine shrimp, they were marketed as 'Sea Monkeys.' They don't actually look like monkeys at all, but were branded as such due to their long tails. When sea monkeys first began to be sold in the United States, they were sold under the brand name 'Instant Life.' Later, when they became known as sea monkeys, the cartoon drawings that were featured in comic books showed creatures that resembled humans more than shrimp. The creative marketing of these creatures can only be described as genius, and at the height of their popularity in the 1970s, they could be found in as many as one in five homes.

2. The butterfly effect is a somewhat poorly understood mathematical concept, primarily because it is interpreted and presented incorrectly by the popular media. It refers to systems, and how initial conditions can influence the ultimate outcome of an event. The best way to understand the concept is through an example. You have two rubber balls. There are two inches between them, and you release them. Where will they end up? Well, that depends. If they're in a sloped, sealed container, they will end up two inches away from each other at the end of the slope. If it's the top of a mountain, however, they may end up miles away from each other. They could bounce off rocks; one could get stuck in a snow bank while the other continues down the slope; one could enter a river and get swept away. The fact that even a tiny initial difference can have a significant overall impact is known as the butterfly effect.

3. Marsupials resemble mammals in a number of ways. For one thing, they are warm-blooded creatures. They have hair, and the mothers feed their young by producing milk. However, one thing that separates marsupials from mammals is that their young are born when they are not yet fully-developed. Most are born after only about four or five weeks. They finish their development in the pouch of their mother. Some of the more commonly known marsupials are koalas, kangaroos, and opossums. They are a diverse group, with many members having little in common besides their reproductive traits.
A major difference between marsupials and mammals is

4. Many people believe that how we express our feelings is mainly determined by our upbringing and culture. Undoubtedly, this is true in some cases. In North America, for example, it is customary to shake hands when we meet somebody to express acceptance, whereas in other countries they may simply bow slightly to indicate this. Many feelings, however, are expressed in similar ways by people all over the world. These emotions include, fear, anger, happiness, disgust, and sorrow. For example, if a person is experiencing fear, their eyes will widen and their pupils will dilate. This reaction is largely involuntary. The finding that people express many feelings in a similar manner, regardless of where they are from, indicates that facial expressions are influenced more by evolution than culture.

5. It is natural for humans to have fears, but when those fears are completely irrational and begin to interfere with everyday activities they are known as phobias. Agoraphobia is a serious phobia, and it can be devastating for those who suffer from it. Contrary to popular belief, agoraphobia is not simply a fear of open spaces. Rather, the agoraphobic fears being in a place that he feels is unsafe. Depending on the severity of the problem, the agoraphobic might fear going to the mall, walking down the street, or even walking to the mailbox. Often, the agoraphobic will view his home as the safest possible place to be, and he may even be reluctant to leave his house. Treatments for this condition include medication and behavioral therapy.
An agoraphobic would feel safest

6. Today's low-fat craze has led many people to assume that all fats are unhealthy, but this is simply not the case. Fat is an essential component of any healthy diet because it provides energy and helps the body process nutrients. While all fats should be consumed in moderation, there are good and bad fats. Good fats are what are known as unsaturated fats. They are found in olive oil, fatty fish like salmon, and nuts. Bad fats are saturated and trans fats. They are found in foods like butter, bacon, and ice cream. Consumption of foods that contain trans or saturated fats should be restricted or avoided altogether.

7. Wells provide water for drinking, bathing, and cleaning to many people across the world. When wells are being dug, there are several issues that must be taken into account to minimize the chance of potential problems down the road. First, it's important to be aware that groundwater levels differ, depending on the season. In general, groundwater levels will be higher during the winter. So if a well is being dug during the winter, it should be deep enough to remain functional during the summer, when water levels are lower. Well water that is used is replaced by melting snow and rain. If the well owners are using the water faster than it can be replaced, however, the water levels will be lowered. The only way to remedy this, aside from waiting for the groundwater to be replenished naturally, is to deepen the well.
From this passage, it can be concluded that

8. Before the battle between CDs and MP3s, there was a rivalry during the 1960s between the four-track and the eight-track tape. Four-track tapes were invented in the early 1960s by Earl Muntz, an entrepreneur from California. Later, Bill Lear designed the eight-track tape. This latter invention was similar in size to the four-track tape, but it could store and play twice as many songs. Lear had close ties with the motor company Ford, and he convinced them to include eight-track players in their vehicles, which definitely helped the eight-track tape to achieve a high level of popularity. Soon after, they began being used in homes, and the four-track tape all but disappeared.
The main difference between the four-track and eight-track tape was

9. Cities are typically warmer than the surrounding countryside, a phenomenon known as the heat island effect. There are numerous causes of this phenomenon, including emissions from cars and buildings. This creates a mini greenhouse effect. In rural areas, the standing water in marshes and ponds evaporates, which cools the air slightly. This does not occur to the same extent in the city. The tall buildings in the center of most cities block winds that would provide some relief from the excessive heat. Finally, the color and material of most roads and buildings absorbs rather than reflects heat. Although planting trees and using building materials that reflect heat may alleviate the problem somewhat, it will by no means eliminate it.

10. Satire is a genre that originated in the ancient world and is still popular today. Although satire is often humorous, its purposes and intentions go well beyond simply making people laugh. Satire is a way for the playwright, author, or television producer to criticize society, human nature, and individuals that he holds in contempt. Satire as we know it today developed in Ancient Greece and Rome. There were three main types. The first, Menippean satire, focused on criticizing aspects of human nature. This was done by introducing stereotypical, one-dimensional characters. Horatian satire can be viewed as gentle satire. It made fun of people and their habits, but in a way that was not offensive. Juvenalian satire was written is such a way that the audience would experience feelings of disgust and aversion when they saw the characters and their actions. Some of the most popular satires today are fake news shows, like the Daily Show and the Colbert Report, and satirical comic strips like Doonesbury.
