Article: The decline in the value of the U.S. dollar corresponds to price inflation, which is a rise in the general level of prices of goods and services in an economy over a period of time. A consumer price index (CPI) is a measure estimating the average price of consumer goods and services purchased by households. The United States Consumer Price Index, published by the Bureau of Labor Statistics, is a measure estimating the average price of consumer goods and services in the United States. It reflects inflation as experienced by consumers in their day-to-day living expenses. A graph showing the U.S. CPI relative to 1982–1984 and the annual year-over-year change in CPI is shown at right.

Question: What does CPI stand for?
Ans: consumer price index


Here is a question about this article: In contemporary society, adolescents also face some risks as their sexuality begins to transform. While some of these, such as emotional distress (fear of abuse or exploitation) and sexually transmitted infections/diseases (STIs/STDs), including HIV/AIDS, are not necessarily inherent to adolescence, others such as teenage pregnancy (through non-use or failure of contraceptives) are seen as social problems in most western societies. One in four sexually active teenagers will contract an STI. Adolescents in the United States often chose "anything but intercourse" for sexual activity because they mistakenly believe it reduces the risk of STIs. Across the country, clinicians report rising diagnoses of herpes and human papillomavirus (HPV), which can cause genital warts, and is now thought to affect 15 percent of the teen population. Girls 15 to 19 have higher rates of gonorrhea than any other age group. One-quarter of all new HIV cases occur in those under the age of 21. Multrine also states in her article that according to a March survey by the Kaiser Family Foundation, eighty-one percent of parents want schools to discuss the use of condoms and contraception with their children. They also believe students should be able to be tested for STIs. Furthermore, teachers want to address such topics with their students. But, although 9 in 10 sex education instructors across the country believe that students should be taught about contraceptives in school, over one quarter report receiving explicit instructions from school boards and administrators not to do so. According to anthropologist Margaret Mead, the turmoil found in adolescence in Western society has a cultural rather than a physical cause; they reported that societies where young women engaged in free sexual activity had no such adolescent turmoil.
What is the answer to this question: What ratio of all new HIV cases occur in those under age 21?
****
So... One-quarter


The problem: Answer a question about this article:
Boston has teams in the four major North American professional sports leagues plus Major League Soccer, and has won 36 championships in these leagues, As of 2014[update]. It is one of six cities (along with Chicago, Detroit, Los Angeles, New York and Philadelphia) to have won championships in all four major sports. It has been suggested that Boston is the new "TitleTown, USA", as the city's professional sports teams have won nine championships since 2001: Patriots (2001, 2003, 2004, and 2014), Red Sox (2004, 2007, and 2013), Celtics (2008), and Bruins (2011). This love of sports has made Boston the United States Olympic Committee's choice to bid to hold the 2024 Summer Olympic Games, but the city cited financial concerns when it withdrew its bid on July 27, 2015.
When did Boston withdraw its bid for hosting the Olympic games?
****
The answer: July 27, 2015


Problem: Please answer a question about the following article about Dwight D. Eisenhower:
Eisenhower responded to the French defeat with the formation of the SEATO (Southeast Asia Treaty Organization) Alliance with the U.K., France, New Zealand and Australia in defense of Vietnam against communism. At that time the French and Chinese reconvened Geneva peace talks; Eisenhower agreed the U.S. would participate only as an observer. After France and the Communists agreed to a partition of Vietnam, Eisenhower rejected the agreement, offering military and economic aid to southern Vietnam. Ambrose argues that Eisenhower, by not participating in the Geneva agreement, had kept the U.S out of Vietnam; nevertheless, with the formation of SEATO, he had in the end put the U.S. back into the conflict.
What is SEATO?
A: Southeast Asia Treaty Organization

Glacial bodies larger than 50,000 km2 (19,000 sq mi) are called ice sheets or continental glaciers. Several kilometers deep, they obscure the underlying topography. Only nunataks protrude from their surfaces. The only extant ice sheets are the two that cover most of Antarctica and Greenland. They contain vast quantities of fresh water, enough that if both melted, global sea levels would rise by over 70 m (230 ft). Portions of an ice sheet or cap that extend into water are called ice shelves; they tend to be thin with limited slopes and reduced velocities. Narrow, fast-moving sections of an ice sheet are called ice streams. In Antarctica, many ice streams drain into large ice shelves. Some drain directly into the sea, often with an ice tongue, like Mertz Glacier.

What is the term for ice that protrude's from a glacier's surface?
Answer: nunataks


Antennas more complex than the dipole or vertical designs are usually intended to increase the directivity and consequently the gain of the antenna. This can be accomplished in many different ways leading to a plethora of antenna designs. The vast majority of designs are fed with a balanced line (unlike a monopole antenna) and are based on the dipole antenna with additional components (or elements) which increase its directionality. Antenna "gain" in this instance describes the concentration of radiated power into a particular solid angle of space, as opposed to the spherically uniform radiation of the ideal radiator. The increased power in the desired direction is at the expense of that in the undesired directions. Power is conserved, and there is no net power increase over that delivered from the power source (the transmitter.)
What is different from a monopole antenna with most other antenna types?
balanced line
