Problem: Printed circuit board:

Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.

Single-layer printed circuit boards have trace layers where?

Problem: Kevin Saunderson's company KMS Records contributed many releases that were as much house music as they were techno. These tracks were well received in Chicago and played on Chicago radio and in clubs.[citation needed] Blake Baxter's 1986 recording, "When we Used to Play / Work your Body", 1987's "Bounce Your Body to the Box" and "Force Field", "The Sound / How to Play our Music" and "the Groove that Won't Stop" and a remix of "Grooving Without a Doubt". In 1988, as house music became more popular among general audiences, Kevin Saunderson's group Inner City with Paris Gray released the 1988 hits "Big Fun" and "Good Life", which eventually were picked up by Virgin Records. Each EP / 12 inch single sported remixes by Mike "Hitman" Wilson and Steve "Silk" Hurley of Chicago and Derrick "Mayday" May and Juan Atkins of Detroit. In 1989, KMS had another hit release of "Rock to the Beat" which was a theme in Chicago dance clubs.[citation needed]

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Puberty occurs through a long process and begins with a surge in hormone production, which in turn causes a number of physical changes. It is the stage of life characterized by the appearance and development of secondary sex characteristics (for example, a deeper voice and larger adam's apple in boys, and development of breasts and more curved and prominent hips in girls) and a strong shift in hormonal balance towards an adult state. This is triggered by the pituitary gland, which secretes a surge of hormonal agents into the blood stream, initiating a chain reaction to occur. The male and female gonads are subsequently activated, which puts them into a state of rapid growth and development; the triggered gonads now commence the mass production of the necessary chemicals. The testes primarily release testosterone, and the ovaries predominantly dispense estrogen. The production of these hormones increases gradually until sexual maturation is met. Some boys may develop gynecomastia due to an imbalance of sex hormones, tissue responsiveness or obesity.
Which gland secretes a surge of hormonal agents into the blood stream?
A: pituitary

Question: The lands of Galicia are ascribed to two different areas in the Koppen climate classification: a south area (roughly, the province of Ourense and Pontevedra) with tendencies to have some summer drought, classified as a warm-summer Mediterranean climate (Csb), with mild temperatures and rainfall usual throughout the year; and the western and northern coastal regions, the provinces of Lugo and A Coruna, which are characterized by their Oceanic climate (Cfb), with a more uniform precipitation distribution along the year, and milder summers. However, precipitation in southern coastal areas are often classified as oceanic since the averages remain significantly higher than a typical mediterranean climate.
Is there an answer to this question: What is the southern area's climate classified as?

Answer: Mediterranean

Problem: United Nations Population Fund:

UNFPA has been falsely accused by anti-family planning groups of providing support for government programs which have promoted forced-abortions and coercive sterilizations. Controversies regarding these claims have resulted in a sometimes shaky relationship between the organization and three presidential administrations, that of Ronald Reagan, George H. W. Bush and George W. Bush, withholding funding from the UNFPA.

Who was UNFPA accurately accused by?
