- Question 1 of 5
Technological globalization is impacted in large part by technological diffusion, the spread of technology across borders. In the last two decades, there has been rapid improvement in the spread of technology to peripheral and semi-peripheral nations, and a 2008 World Bank report discusses both the benefits and ongoing challenges of this diffusion. In general, the report found that technological progress and economic growth rates were linked, and that the rise in technological progress has helped improve the situations of many living in absolute poverty. The report recognizes that rural and low-tech products such as corn can benefit from new technological innovations, and that, conversely, technologies like mobile banking can aid those whose rural existence consists of low-tech market vending. In addition, technological advances in areas like mobile phones can lead to competition, lowered prices, and concurrent improvements in related areas such as mobile banking and information sharing.
Q. The words this diffusion refers to …CorrectIncorrect

The Sapir-Whorf Hypothesis
The Sapir-Whorf hypothesis is based on the idea that people experience their world through their language, and that they therefore understand their world through the culture embedded in their language. The hypothesis, which has also been called linguistic relativity, states that language shapes thought. Studies have shown, for instance, that unless people have access to the word “ambivalent,” they don’t recognize an experience of uncertainty due to conflicting positive and negative feelings about one issue. Essentially, the hypothesis argues, if a person can’t describe the experience, the person is not having the experience.
Q. The word they refers to …CorrectIncorrect

Hunter-gatherer societies demonstrate the strongest dependence on the environment of the various types of preindustrial societies. As the basic structure of human society until about 10,000–12,000 years ago, these groups were based around kinship or tribes. Hunter-gatherers relied on their surroundings for survival—they hunted wild animals and foraged for uncultivated plants for food. When resources became scarce, the group moved to a new area to find sustenance, meaning they were nomadic. These societies were common until several hundred years ago, but today only a few hundred remain in existence, such as indigenous Australian tribes sometimes referred to as “aborigines,” or the Bambuti, a group of pygmy hunter-gatherers residing in the Democratic Republic of Congo. Hunter-gatherer groups are quickly disappearing as the world’s population explodes.
Q. The phrase these groups refers to …CorrectIncorrect
- Question 4 of 5
A high level of appreciation for one’s own culture can be healthy; a shared sense of community pride, for example, connects people in a society. But ethnocentrism can lead to disdain or dislike for other cultures, causing misunderstanding and conflict. People with the best intentions sometimes travel to a society to “help” its people, seeing them as uneducated or backward; essentially inferior. In reality, these travelers are guilty of cultural imperialism, the deliberate imposition of one’s own cultural values on another culture. Europe’s colonial expansion, begun in the 16th century, was often accompanied by a severe cultural imperialism. European colonizers often viewed the people in the lands they colonized as uncultured savages who were in need of European governance, dress, religion, and other cultural practices. A more modern example of cultural imperialism may include the work of international aid agencies who introduce agricultural methods and plant species from developed countries while overlooking indigenous varieties and agricultural approaches that are better suited to the particular region.
Q. The words these travelers refer to …CorrectIncorrect

Measuring Blood Pressure
Blood pressure is measured using a device called a sphygmomanometer (Greek sphygmos = “pulse”). It consists of an inflatable cuff to restrict blood flow, a manometer to measure the pressure, and a method of determining when blood flow begins and when it becomes impeded. Since its invention in 1881, it has been an essential medical device. There are many types of sphygmomanometers: manual ones that require a stethoscope and are used by medical professionals; mercury ones, used when the most accuracy is required; less accurate mechanical ones; and digital ones that can be used with little training but that have limitations. When using a sphygmomanometer, the cuff is placed around the upper arm and inflated until blood flow is completely blocked, then slowly released. As the heart beats, blood forced through the arteries causes a rise in pressure. This rise in pressure at which blood flow begins is the systolic pressure—the peak pressure in the cardiac cycle. When the cuff’s pressure equals the arterial systolic pressure, blood flows past the cuff, creating audible sounds that can be heard using a stethoscope. This is followed by a decrease in pressure as the heart’s ventricles prepare for another beat. As cuff pressure continues to decrease, eventually sound is no longer heard; this is the diastolic pressure—the lowest pressure (resting phase) in the cardiac cycle.
