Problem: Memory:

Stressful life experiences may be a cause of memory loss as a person ages. Glucocorticoids that are released during stress damage neurons that are located in the hippocampal region of the brain. Therefore, the more stressful situations that someone encounters, the more susceptible they are to memory loss later on. The CA1 neurons found in the hippocampus are destroyed due to glucocorticoids decreasing the release of glucose and the reuptake of glutamate. This high level of extracellular glutamate allow calcium to enter NMDA receptors which in return kills neurons. Stressful life experiences can also cause repression of memories where a person moves an unbearable memory to the unconscious mind. This directly relates to traumatic events in one's past such as kidnappings, being prisoners of war or sexual abuse as a child.

What will a person often do with extremely stressful thoughts?

Problem: Like many older east coast cities after World War II, Atlantic City became plagued with poverty, crime, corruption, and general economic decline in the mid-to-late 20th century. The neighborhood known as the "Inlet" became particularly impoverished. The reasons for the resort's decline were multi-layered. First of all, the automobile became more readily available to many Americans after the war. Atlantic City had initially relied upon visitors coming by train and staying for a couple of weeks. The car allowed them to come and go as they pleased, and many people would spend only a few days, rather than weeks. Also, the advent of suburbia played a huge role. With many families moving to their own private houses, luxuries such as home air conditioning and swimming pools diminished their interest in flocking to the luxury beach resorts during the hot summer. But perhaps the biggest factor in the decline in Atlantic City's popularity came from cheap, fast jet service to other premier resorts, such as Miami Beach and the Bahamas.
What was the biggest factor in the decline in Atlantic City's popularity?

Answer: cheap, fast jet service

Iran's climate ranges from arid or semiarid, to subtropical along the Caspian coast and the northern forests. On the northern edge of the country (the Caspian coastal plain) temperatures rarely fall below freezing and the area remains humid for the rest of the year. Summer temperatures rarely exceed 29 C (84.2 F). Annual precipitation is 680 mm (26.8 in) in the eastern part of the plain and more than 1,700 mm (66.9 in) in the western part. United Nations Resident Coordinator for Iran Gary Lewis has said that "Water scarcity poses the most severe human security challenge in Iran today".
What is the annual precipitation in Iran's eastern plains?
A: 680 mm (26.8 in)

Context and question: Some multiracial individuals feel marginalized by U.S. society. For example, when applying to schools or for a job, or when taking standardized tests, Americans are sometimes asked to check boxes corresponding to race or ethnicity. Typically, about five race choices are given, with the instruction to "check only one." While some surveys offer an "other" box, this choice groups together individuals of many different multiracial types (ex: European Americans/African-Americans are grouped with Asian/Native American Indians).
What does the "other" box do?
Answer: groups together individuals of many different multiracial types

Question: During the Early Modern period (approximately late 15th century to 1800), the universities of Europe would see a tremendous amount of growth, productivity and innovative research. At the end of the Middle Ages, about 400 years after the first university was founded, there were twenty-nine universities spread throughout Europe. In the 15th century, twenty-eight new ones were created, with another eighteen added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe and Eastern Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time. It should be noted that the identification of a university was not necessarily obvious during the Early Modern period, as the term is applied to a burgeoning number of institutions. In fact, the term "university" was not always used to designate a higher education institution. In Mediterranean countries, the term studium generale was still often used, while "Academy" was common in Northern European countries.
Is there an answer to this question: The German Empire had how many universities?

Answer: 34

The third-generation iPod had a weak bass response, as shown in audio tests. The combination of the undersized DC-blocking capacitors and the typical low-impedance of most consumer headphones form a high-pass filter, which attenuates the low-frequency bass output. Similar capacitors were used in the fourth-generation iPods. The problem is reduced when using high-impedance headphones and is completely masked when driving high-impedance (line level) loads, such as an external headphone amplifier. The first-generation iPod Shuffle uses a dual-transistor output stage, rather than a single capacitor-coupled output, and does not exhibit reduced bass response for any load.
What part of audio output was substandard on 3rd generation iPods?
A:
bass
