What is the last period of Buddhism?

Problem: Before the pact's announcement, Communists in the West denied that such a treaty would be signed. Future member of the Hollywood Ten Herbert Biberman denounced rumors as "Fascist propaganda". Earl Browder, head of the Communist Party USA, stated that "there is as much chance of agreement as of Earl Browder being elected president of the Chamber of Commerce." Beginning in September 1939, the Soviet Comintern suspended all anti-Nazi and anti-fascist propaganda, explaining that the war in Europe was a matter of capitalist states attacking each other for imperialist purposes. Western Communists acted accordingly; while before they supported protecting collective security, now they denounced Britain and France going to war.
Who accepted the involvement of Britain and France in a war with Germany?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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 force might damage a PCB if large components are surface mounted?
A: mechanical stress


Context and question: Insects were the earliest organisms to produce and sense sounds. Insects make sounds mostly by mechanical action of appendages. In grasshoppers and crickets, this is achieved by stridulation. Cicadas make the loudest sounds among the insects by producing and amplifying sounds with special modifications to their body and musculature. The African cicada Brevisana brevis has been measured at 106.7 decibels at a distance of 50 cm (20 in). Some insects, such as the Helicoverpa zeamoths, hawk moths and Hedylid butterflies, can hear ultrasound and take evasive action when they sense that they have been detected by bats. Some moths produce ultrasonic clicks that were once thought to have a role in jamming bat echolocation. The ultrasonic clicks were subsequently found to be produced mostly by unpalatable moths to warn bats, just as warning colorations are used against predators that hunt by sight. Some otherwise palatable moths have evolved to mimic these calls. More recently, the claim that some moths can jam bat sonar has been revisited. Ultrasonic recording and high-speed infrared videography of bat-moth interactions suggest the palatable tiger moth really does defend against attacking big brown bats using ultrasonic clicks that jam bat sonar.
What were the earliest organisms to produce sound?
Answer: Insects


Question: Robert S. Wood has argued that the United States is a model for the world in terms of how a separation of church and state—no state-run or state-established church—is good for both the church and the state, allowing a variety of religions to flourish. Speaking at the Toronto-based Center for New Religions, Wood said that the freedom of conscience and assembly allowed under such a system has led to a "remarkable religiosity" in the United States that isn't present in other industrialized nations. Wood believes that the U.S. operates on "a sort of civic religion," which includes a generally-shared belief in a creator who "expects better of us." Beyond that, individuals are free to decide how they want to believe and fill in their own creeds and express their conscience. He calls this approach the "genius of religious sentiment in the United States."
Is there an answer to this question:  Where did the Center for New Religions leave?

Answer: unanswerable


QUES: The Gorals of southern Poland and northern Slovakia are partially descended from Romance-speaking Vlachs who migrated into the region from the 14th to 17th centuries and were absorbed into the local population. The population of Moravian Wallachia also descend of this population.
