Here is a question about this article: Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side. Once surface-mounting came into use, small-sized SMD components were used where possible, with through-hole mounting only of components unsuitably large for surface-mounting due to power requirements or mechanical limitations, or subject to mechanical stress which might damage the PCB.
What is the answer to this question: What type of boards end up with limited routing space in through-hole manufacture?
****
So... multi-layer


The problem: Answer a question about this article:
The predominant school of thought in the 13th century was the Thomistic reconciliation of the teachings of Aristotle with Christian theology. The Condemnation of 1277, enacted at the University of Paris, placed restrictions on ideas that could be interpreted as heretical; restrictions that had implication for Aristotelian thought. An alternative was presented by William of Ockham, who insisted that the world of reason and the world of faith had to be kept apart. Ockham introduced the principle of parsimony – or Occam's razor – whereby a simple theory is preferred to a more complex one, and speculation on unobservable phenomena is avoided.
Which philosophy attempted to reconcile Aristotelian teachings and Christian theology in the 13th century?
****
The answer: Thomistic


Problem: Please answer a question about the following article about The Bronx:
Since then, the Bronx has always supported the Democratic Party's nominee for President, starting with a vote of 2-1 for the unsuccessful Al Smith in 1928, followed by four 2-1 votes for the successful Franklin D. Roosevelt. (Both had been Governors of New York, but Republican former Gov. Thomas E. Dewey won only 28% of the Bronx's vote in 1948 against 55% for Pres. Harry Truman, the winning Democrat, and 17% for Henry A. Wallace of the Progressives. It was only 32 years earlier, by contrast, that another Republican former Governor who narrowly lost the Presidency, Charles Evans Hughes, had won 42.6% of the Bronx's 1916 vote against Democratic President Woodrow Wilson's 49.8% and Socialist candidate Allan Benson's 7.3%.)
Who did the Bronx support for President in 1928?
A: Al Smith

Mali faces numerous health challenges related to poverty, malnutrition, and inadequate hygiene and sanitation. Mali's health and development indicators rank among the worst in the world. Life expectancy at birth is estimated to be 53.06 years in 2012. In 2000, 62–65 percent of the population was estimated to have access to safe drinking water and only 69 percent to sanitation services of some kind. In 2001, the general government expenditures on health totalled about US$4 per capita at an average exchange rate.

As of 2012 50.3 years is considered the Malian peoples averages of what statistic?
Answer: Life expectancy


Problem: 20th Street starts at Avenue C, and 21st and 22nd Streets begin at First Avenue. They all end at Eleventh Avenue. Travel on the last block of the 20th, 21st and 22nd Streets, between Tenth and Eleventh Avenues, is in the opposite direction than it is on the rest of the respective street. 20th Street is very wide from the Avenue C to First Avenue.
What is different about 20th Street between Avenue C and First Avenue?
The answer is the following: very wide


Input: Article: On 14 October, the heaviest night attack to date saw 380 German bombers from Luftflotte 3 hit London. Around 200 people were killed and another 2,000 injured.
