Problem: Sichuan:

Sichuan is one of the major industrial centers of China. In addition to heavy industries such as coal, energy, iron and steel, the province has also established a light industrial sector comprising building materials, wood processing, food and silk processing. Chengdu and Mianyang are the production centers for textiles and electronics products. Deyang, Panzhihua, and Yibin are the production centers for machinery, metallurgical industries, and wine, respectively. Sichuan's wine production accounted for 21.9% of the country’s total production in 2000.

What areas are major building materials for textiles and electronics?

Problem: Occupancy sensors to allow operation for whenever someone is within the area being scanned can control lighting. When motion can no longer be detected, the lights shut off. Passive infrared sensors react to changes in heat, such as the pattern created by a moving person. The control must have an unobstructed view of the building area being scanned. Doors, partitions, stairways, etc. will block motion detection and reduce its effectiveness. The best applications for passive infrared occupancy sensors are open spaces with a clear view of the area being scanned. Ultrasonic sensors transmit sound above the range of human hearing and monitor the time it takes for the sound waves to return. A break in the pattern caused by any motion in the area triggers the control. Ultrasonic sensors can see around obstructions and are best for areas with cabinets and shelving, restrooms, and open areas requiring 360-degree coverage. Some occupancy sensors utilize both passive infrared and ultrasonic technology, but are usually more expensive. They can be used to control one lamp, one fixture or many fixtures.

Question: Since 1642 (in the 13 colonies, the United States under the Articles of Confederation, and the current United States) an estimated 364 juvenile offenders have been put to death by the states and the federal government. The earliest known execution of a prisoner for crimes committed as a juvenile was Thomas Graunger in 1642. Twenty-two of the executions occurred after 1976, in seven states. Due to the slow process of appeals, it was highly unusual for a condemned person to be under 18 at the time of execution. The youngest person to be executed in the 20th century was George Stinney, who was electrocuted in South Carolina at the age of 14 on June 16, 1944. The last execution of a juvenile may have been Leonard Shockley, who died in the Maryland gas chamber on April 10, 1959, at the age of 17. No one has been under age 19 at time of execution since at least 1964. Since the reinstatement of the death penalty in 1976, 22 people have been executed for crimes committed under the age of 18. Twenty-one were 17 at the time of the crime. The last person to be executed for a crime committed as a juvenile was Scott Hain on April 3, 2003 in Oklahoma.
Is there an answer to this question: About how many American juveniles have been executed since 1842?

Answer: unanswerable


From 1966, Witness publications and convention talks built anticipation of the possibility that Christ's thousand-year reign might begin in late 1975 or shortly thereafter. The number of baptisms increased significantly, from about 59,000 in 1966 to more than 297,000 in 1974. By 1975, the number of active members exceeded two million. Membership declined during the late 1970s after expectations for 1975 were proved wrong. Watch Tower Society literature did not state dogmatically that 1975 would definitely mark the end, but in 1980 the Watch Tower Society admitted its responsibility in building up hope regarding that year.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the Watch Tower Society admit in 1980?
Ah, so..
its responsibility in building up hope
