Problem: Printed circuit board:

There are quite a few different dielectrics that can be chosen to provide different insulating values depending on the requirements of the circuit. Some of these dielectrics are polytetrafluoroethylene (Teflon), FR-4, FR-1, CEM-1 or CEM-3. Well known pre-preg materials used in the PCB industry are FR-2 (phenolic cotton paper), FR-3 (cotton paper and epoxy), FR-4 (woven glass and epoxy), FR-5 (woven glass and epoxy), FR-6 (matte glass and polyester), G-10 (woven glass and epoxy), CEM-1 (cotton paper and epoxy), CEM-2 (cotton paper and epoxy), CEM-3 (non-woven glass and epoxy), CEM-4 (woven glass and epoxy), CEM-5 (woven glass and polyester). Thermal expansion is an important consideration especially with ball grid array (BGA) and naked die technologies, and glass fiber offers the best dimensional stability.

What pre-preg material is designated by "FR-2"?

A: phenolic cotton paper


Problem: The total adult literacy rate is 99 percent. Portuguese primary school enrollments are close to 100 percent. According to the OECD's Programme for International Student Assessment (PISA) 2009, the average Portuguese 15-year-old student, when rated in terms of reading literacy, mathematics and science knowledge, is placed at the same level as those students from the United States, Sweden, Germany, Ireland, France, Denmark, United Kingdom, Hungary and Taipei, with 489 points (493 is the average). Over 35% of college-age citizens (20 years old) attend one of the country's higher education institutions (compared with 50% in the United States and 35% in the OECD countries). In addition to being a destination for international students, Portugal is also among the top places of origin for international students. All higher education students, both domestic and international, totaled 380,937 in 2005.
What percentage of college-age citizens attend a higher education institution in Portugal?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
For example, character 10 represents the "line feed" function (which causes a printer to advance its paper), and character 8 represents "backspace". RFC 2822 refers to control characters that do not include carriage return, line feed or white space as non-whitespace control characters. Except for the control characters that prescribe elementary line-oriented formatting, ASCII does not define any mechanism for describing the structure or appearance of text within a document. Other schemes, such as markup languages, address page and document layout and formatting.
What do the "line feed" control characters do?
A: unanswerable

The business pages begin on the centre spread, and are followed by The Register, containing obituaries, Court & Social section, and related material. The sport section is at the end of the main paper. The Times current prices are £1.20 for the daily edition and £1.50 for the Saturday edition.
What feature begins on the centre spread of The Times?
Answer: business pages


Question: The average temperature is 61.4 °F (16.3 °C), with the monthly daily average ranging from 39.2 °F (4.0 °C) in January to 83.0 °F (28.3 °C) in July. Extremes range from −17 °F (−27 °C) on February 12, 1899 to 113 °F (45 °C) on August 11, 1936 and August 3, 2012; the last sub-zero (°F) reading was −5 °F (−21 °C) on February 10, 2011. Temperatures reach 100 °F (38 °C) on 10.4 days of the year, 90 °F (32 °C) on nearly 70 days, and fail to rise above freezing on 8.3 days. The city receives about 35.9 inches (91.2 cm) of precipitation annually, of which 8.6 inches (21.8 cm) is snow.
Is there an answer to this question: Out of the precipitation that falls, how much of it is snow?

Answer: 8.6 inches


QUES: Shared doctrines would include beliefs about one God; the virgin birth; miracles; atonement for sins through the death, burial, and bodily resurrection of Jesus; the Trinity; the need for salvation (through belief in Jesus Christ as the son of God, his death and resurrection, and confession of Christ as Lord); grace; the Kingdom of God; last things (eschatology) (Jesus Christ will return personally and visibly in glory to the earth, the dead will be raised, and Christ will judge everyone in righteousness); and evangelism and missions. Some historically significant Baptist doctrinal documents include the 1689 London Baptist Confession of Faith, 1742 Philadelphia Baptist Confession, the 1833 New Hampshire Baptist Confession of Faith, the Southern Baptist Convention's Baptist Faith and Message, and written church covenants which some individual Baptist churches adopt as a statement of their faith and beliefs.
